Binary PNM formats pnmraw = {ppmraw (color pixmap), pgmraw (graymap), and pbmraw (black-and-white bitmap)} are strongly preferred. Output stream can be locally processed by Hewlett-Packard's Printing Performance Architecture (PPA) printers (HP DeskJet 710C, 712C, 720C, 722C, 820C, and 1000C series). .PP (PNM format output can be produced from PostScript(tm) input by the GhostScript output devices "pbmraw", "pgmraw" or "ppmraw", or by "pnmraw", which will choose one of these formats as appropriate for the document.) \fBpnm2ppa\fP assumes the input resolution is 600dpi (or 300dpi if the command-line option \fB--dpi300\fP is used): input at higher/lower resolutions will result in a correspondingly larger/smaller printed image, provided it is within the printer's allowed size range. .PP .SH OPTIONS .\"{{{ -b bottommargin .IP "\fB\-b \fIbottommargin\fR\fP" Sets the bottom margin \fIbottommargin\fR in units of 1/600 inches (e.g., \fB -b 150\fP corresponds to 0.25"). .\"}}} .\"{{{ -B blackness .IP "\fB\-B \fIblackness\fR\fP" Sets the black ink density \fIblackness\fR in drops per pixel (0,1,2,3,4). .\"}}} .\"{{{ --bi .IP "\fB\--bi\fP" Force bidirectional print sweeps. .\"}}} .\"{{{ --bw .IP "\fB\--bw\fP" Disables the color cartridge; will print in grey scale using only the black cartridge. .\"}}} .\"{{{ -d .IP "\fB\-d\fP" Displays the current configuration. .\"}}} .\"{{{ --dpi300 .IP "\fB\--dpi300\fP" Treat input resolution as 300dpi instead of 600dpi. .\"}}} .\"{{{ --eco .IP "\fB\--eco\fP" Econofast mode: lower print quality that is faster and saves ink. .\"}}} .\"{{{ -f configFile .IP "\fB\-f \fIconfigFile\fR\fP" Re-reads configuration from \fIconfigFile\fR (after initially reading it from /etc/pnm2ppa.conf). .\"}}} .\"{{{ -F GammaFile .IP "\fB\-F \fIGammaFile\fR\fP" Overrides reading the color-correction table (Gamma curve) from the default file /etc/pnm2ppa.gamma, and uses \fIGammaFile\fR instead. .\"}}} .\"{{{ --fd .IP "\fB\--fd\fP" Enable fast ordered dithering instead of using the slower, but beautiful, Floyd-Steinberg dithering.

PPA Printer calibration for pnm2ppa <author>The pnm2ppa project team <htmlurl url="mailto:ppa-rpms@sourceforge.net" name="ppa-rpms@users.sourceforge.net"> <date>v0.4, October 28, 2000 <abstract> Information and instructions for printer calibration using pnm2ppa. <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa"> (Updated for pnm2ppa-1.02 and later.) </abstract> <!-- Begin the document --> <p> <bf> Overview of Printer Calibration.</bf> There are three main tasks you may need to carry out to fine-tune your PPA printer: <itemize> <item>Adjust the x-offset and y-offset to <bf>correctly center the printed page on the paper</bf> <item>Adjust the relative offsets between black and colored ink printing - <bf>this should be done each time you replace an ink cartridge</bf>. <item> Match the colors of printed images to some other output device - this is <bf>color correction</bf> and is described in <htmlurl url="./COLOR.html" name="COLOR.html"> (or COLOR.txt). </itemize> These instructions assume that you are already able to print postscript files with your PPA printer. If your print filters are properly configured, something like "<tt>lpr test.ps</tt>" will successfully invoke ghostscript and pnm2ppa to print the postscript file test.ps. Alternatively, you may be using shell scripts like "lprbw", "lprcolor" and "lpreco" supplied with the pnm2ppa source code, and modified by you for your defaults; you may also have defined special printing devices in <tt>/etc/printcap</tt>, e.g. a "coloreco" device so you print with <tt>lpr -P coloreco test.ps</tt>. These details vary with the operating system and distribution you use. <p> <bf> (1) Centering the printed page on the paper. </bf> This is done by adjusting the x-offset and y-offset parameters <bf>xoffset</bf> and <bf>yoffset</bf> in the <tt>pnm2ppa</tt> configuration file (usually <tt>/etc/pnm2ppa.conf</tt>). The parameters are given in units of 1/600 inch; increasing <tt>xoffset</tt> moves the image to the right, and increasing <tt>yoffset</tt> moves it downwards. These offsets now have default values defined for each printer model, and you will probably not need to adjust them. Uncomment and make small adjustments to the default values for these in the configuration file, until the printout is satisfactory. (You can also use the '-x' and '-y' command-line parameters.) There are two ways to check the offsets. <itemize> <item>either <bf>using the "<tt>calibrate_ppa</tt>" program.</bf> <item>or <bf>printing a suitable test page</bf>. </itemize> <p> The "<tt>calibrate_ppa</tt>" program is a stand-alone program distributed with <tt>pnm2ppa</tt> which creates various test patterns in the raw pixmap format accepted by pnm2ppa. (The three paper sizes, US Letter, US Legal, and A4, are supported). If your paper size is A4, and your printer filter accepts the "<tt>-l</tt>" (direct output) option to <tt>lpr</tt>, the command to run is: <tscreen><verb> calibrate_ppa -s a4 --center | pnm2ppa --bw -i - -o - | lpr -l </verb></tscreen> (Substitute "letter" or "legal" for "a4" to change the papersize; if no paper size is specified, it is assumed to be <tt>letter</tt>.) If "<tt>lpr -l</tt>" is not valid, you need to know which port your printer is attached to. Assuming it is <tt>/dev/lp0</tt>, the above command becomes <tt> calibrate_ppa -s a4 --center | pnm2ppa --bw -i - -o /dev/lp0</tt>. The pattern shows distances from the edge of the printed page in units of 50 dots (1/12 inch), and diagonal lines that should point to the corners. Change <tt>xoffset</tt> and <tt>yoffset</tt> in the configuration file (usually <tt>/etc/pnm2ppa.conf</tt> to center the pattern. The configuration file is supplied with commented-out entries like <tt>#xoffset 160</tt> showing the default value. Remove the "<tt>#</tt>" to activate the entry. In Red Hat or Mandrake Linux distributions, a suitable test page is <tt>/usr/lib/rhs/rhs-printfilters/testpage.ps</tt> (US Letter paper) or <tt>/usr/lib/rhs/rhs-printfilters/testpage-a4.ps</tt> (A4 paper). (If these are not available, similar test pages are supplied in the pnm2ppa source distribution.) These pages have margins drawn at standard distances from the edges of the paper, and can also be used to check the centering, but are not as accurate <bf> (2) Calibrating the X and Y Color Head Offsets. </bf> The color ink offsets now have to be calibrated with respect to the black ink. Because the relative position of the two ink cartridges can move slightly, <bf>this must be done whenever an ink cartridge is removed and replaced</bf>. To print an alignment calibration pattern on a4 paper, run <tscreen><verb> calibrate_ppa -s a4 --align | pnm2ppa --fd -i - -o - | lpr -l </verb></tscreen> On the printed page, there are four alignment patterns, corresponding to configuration file parameters <bf>ColOffsX</bf>, <bf>ColOffsY</bf>, <bf>colorshear</bf> and <bf>blackshear</bf>. The central alignment patterns, labelled "0" should be perfectly aligned. If they are not, first correct the shearing patterns, (see below). Then identify the best-aligned <bf>ColOffsX</bf> and <bf>ColOffsY</bf> patterns, and add or subtract the positive or negative number below the pattern from the value in the configuration file. Check the result by printing the alignment test pattern: <tscreen><verb> calibrate_ppa --test | pnm2ppa -fd -i - -o - | lpr -l </verb></tscreen> The lines in the cross and square should be perfectly straight now. The calibration can also be done by printing the test page <tt>test.ps</tt> (found in the tarball <tt>pnm2ppa-1.0.tar.gz</tt>; or installed with the <tt>pnm2ppa</tt> documentation. (This is often in <tt>/usr/doc/pnm2ppa*/</tt>.) On the printout you see several images: <itemize> <item>top left, you see a square with both black and colored items. These should align correctly, or you have to change your settings. <item>You see a large vertical bar, and also a horizontal bar. On the sides of the vertical bar there are a blue and a green line. These should align with the 0 mark. <item> You also see a small vertical, and horizontal, bar, with a red bar on its side. </itemize> If these items do NOT line up, you should take the following steps: <itemize> <item> (1) take for the large bar the number of the tickmark just smaller than the place where the green and blue lines point to. The minor tick marks are 25 points. <item> (2) To this number, add the number of the tick mark at which a red tick mark exactly lines up. This might not work if the offsets are way off; in that case, apply the correction of step 1, and print again. <item> (3) Add the horizontal offset to the value of <bf>ColOffsX</bf>, and the vertical offset to the value of <bf>ColOffsY</bf> in the configuration file. </itemize> Now you can print test.ps again to see whether this procedure worked. <bf>Shearing adjustments</bf> If bidirectional printing causes "shearing" of vertical lines (horizontal offsets of those parts of the line printed by left-to-right print-head sweeps relative to those printed on right-to-left sweeps) you can make small adjustments (in 1/600 inch) units using the <bf>blackshear</bf> and <bf>colorshear</bf> parameters in the configuration file. You can also suppress bidirectional printing with a <bf>unimode 1</bf> configuration file entry. The third and fourth lines on the color head offset calibration page (see above) correspond to color and black print head shearing corrections. If the central alignment patterns (labeled "0") are not aligned, add or subtract the positive or negative number below the best-aligned pattern from the <tt>colorshear</tt> and <tt>blackshear</tt> values in the configuration file. <bf>Cleaning the Print Heads</bf> You can use <tt>calibrate_ppa</tt> to clean the print heads by printing patterns that exercise all the ink nozzles: <tscreen><verb> calibrate_ppa --clean | pnm2ppa -p -i - -o - | lpr -l calibrate_ppa --clean | pnm2ppa --bw -i - -o - | lpr -l </verb></tscreen> The first of these commands prints a cleaning pattern with colored ink, the second uses black ink. <bf>Other adjustments</bf> The parameter <bf>blackness</bf> adjusts the number of black ink drops printed per pixel. It takes values 1, 2, 3, or 4 (2 is the default). Other values, like 0, suppress black ink. Inks can also be suppressed by configuration file entries <tt>black_ink 0</tt>, <tt>color_ink 0</tt>, <tt>cyan_ink 0</tt>, <tt>magenta_ink 0</tt>, or <tt>yellow_ink 0</tt>. These are mainly useful for debugging the printer driver. </article> ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������pnm2ppa-1.13/docs/en/sgml/COLOR.sgml����������������������������������������������������������������0000644�0000764�0000764�00000016565�07176621443�014031� �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������<!doctype linuxdoc system> <article> <!-- Title information --> <title>Color correction for pnm2ppa <author>The pnm2ppa project team <htmlurl url="mailto:ppa-rpms@sourceforge.net" name="ppa-rpms@users.sourceforge.net"> <date> v0.6, October 28, 2000 <abstract> Information and instructions for color correction of pnm2ppa color printing. <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa"> (Updated for pnm2ppa-1.0 and later.) </abstract> <!-- Begin the document --> <p> <bf> Overview of Color correction.</bf> Color Pixmap input to <tt>pnm2ppa</tt> (ppm format, produced by the ghostscript output devices <tt>ppmraw</tt> or <tt>ppm</tt>) specifies the color of a pixel as three coordinates (Red, Green, Blue) in the range 0-255. The program <tt>pnm2ppa</tt> converts these to relative amounts of Cyan, Magenta and Yellow ink drops printed on the page. <bf>Color correction</bf> allows the user to attempt to match the printed colors to some reference colors, such as those displayed on the terminal, or those printed on a different printer, or those printed on the same printer with a different driver (such as the Win9x drivers supplied by HP with their PPA printers). The color output from <tt>pnm2ppa</tt> can be controlled in two ways: <itemize> <item> by a color correction "gamma" file, if it is installed. By default this file is <tt>/etc/pnm2ppa.gamma</tt>, but it may also be specified with the pnm2ppa option <tt> pnm2ppa ... -F gammafile ... </tt>. <item> if there is no gamma file, by three values specified by keywords ( either <tt>GammaR</tt>, <tt>GammaG</tt>, <tt>GammaB</tt> or <tt>RedGammaIdx</tt>, <tt>BlueGammaIdx</tt>, <tt>GreenGammaIdx</tt>) in the <tt>pnm2ppa</tt> configuration file. </itemize> <tt>pnm2ppa</tt> will carry out <bf>"color correction"</bf>, unless it is called with the <bf>--noGamma</bf> command line option. However, unless you set up a color correction scheme, the default color correction does not change any colors. Color correction is specified by three color intensity functions (curves), one for each of Red, Green, and Blue. In their simplest form, these curves have a standard form controlled by a single "gamma" parameter such as <tt>GammaR</tt>. The more sophisticated correction, in the file <tt>pnm2ppa.gamma</tt>, specifies these curves more generally as a table of numbers that translate each possible color intensity value to a new value. Note that, in principle, different color corrections are needed for different print quality settings, and for different brands and qualities of paper! At present the methods for constructing a color correction for <tt>pnm2ppa</tt> are not very user-friendly. If you can improve them, please help!. <bf> Color correction with "gamma" values in the configuration file.</bf> <p> The PixMap (ppa) format specifies colors by an intensity for each primary color, Red, Green and Blue, in the range 0-255, so (0,0,0) is black, and (255,255,255) is white. The standard color intensity enhancement function replaces the ppm intensity <tt>i</tt> of each primary color by <tt> Enh(i) </tt> which is the closest integer to ( i / 256) raised to the power <tt>Gamma</tt>, times 256. You can specify the Gamma values in the configuration file as decimal numbers <tt>GammaR</tt>, <tt>GammaG</tt>, <tt>GammaB</tt>, but how do you find out what values to choose?. Perhaps by experimenting with changing the Gamma values. A source of information on Gamma color correction is <htmlurl url="http://www.cgsd.com/papers/gamma.html" name="www.cgsd.com/papers/gamma.html"> One method for constructing a Gamma correction has been built into <tt>pnm2ppa</tt>, but it wastes quite a lot of ink, and many users find it less effective than producing a customized color correction curve as described in the next section. You must first use pnm2ppa to print a color test page, and then generate a file <tt>gamma.ppm</tt> to compare to it. To do this, type <tscreen><verb> pnm2ppa -g -i - -o /dev/lp0 </verb></tscreen> (replace <tt>/dev/lp0</tt> by whatever printer device your PPA printer uses, or use <tt> ... -o - | lpr -l </tt>, etc.). Note also that as <tt>pnm2ppa</tt> is not receiving any ghostscript input to tell it the paper size, this must be correctly specified by a configuration file entry or, e.g., a <tt> -s a4 </tt> option, if the default US Letter paper is not being used. This procedure will print a color calibration page. The printed output is an array of sets of three colored bands, red, blue and green, each of which increases in brightness from left to right. The topmost set of bands should be referrred to as bands "0", the next ones as "1", etc. Next, run the extra program <tt>calibrate_ppa</tt> which will produce a (large, 10MB) PixMap (ppm) file: <tscreen><verb> calibrate_ppa -g -o gamma.ppm </verb></tscreen> This will produce the PixMap file as <tt>gamma.ppm</tt> in the current directory. To color-correct the printer so that its colors match those on the terminal screen, you should now attempt to view the file <tt>gamma.ppm</tt> using some application (such as the GNU image manipulation program <tt>gimp</tt>, or <tt>xv</tt>) that can view <tt>.ppm</tt> files. For each color, identify the printed band (0, 1, 2, ... etc) that most closely corresponds to the brightness profile shown on the screen. The default values are now: <tscreen><verb> RedGammaIdx 0 GreenGammaIdx 0 BlueGammaIdx 0 </verb></tscreen> (i.e., no color correction). Enter your modified values for these in the <tt>pnm2ppa</tt> configuration file (usually <tt>/etc/pnm2ppa.conf</tt>). The actual Gamma value is then <bf>1.0 - 0.033*(Color)GammaIdx </bf>; To color-correct with respect to another printer (or the Win9x drivers), you must manage to print <tt>gamma.ppm</tt> on that other device, then make the comparison. (Or print the output of <tt>pnm2ppa -g </tt> on that device; the top line is the same uncorrected color data as <tt>gamma.ppm</tt>.) <bf> Color correction using a "gamma file". </bf> A "gamma correction file" is a binary file containing 3 x 256 numbers, which are lookup tables of corrected red green and blue color intensities. The program <tt>pnm2ppa</tt> will use a default correction file <tt>/etc/pnm2ppa.gamma</tt> if it exists, unless the <tt>--noGamma </tt> option is used. The default correction file location can be changed by using the <tt>pnm2ppa</tt> option <tt>-F gammafile </tt>, where "gammafile" is the name (including the full path) of the gamma correction file to be used. Currently, there are two available tools for constructing a gamma correction file: <itemize> <item> A graphical utility <tt>ppagammacorrect</tt> is available in the PPA Color Correction Utilities section of the <tt>pnm2ppa</tt> web page <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa">, (but at the time of writing, this appears to be frozen in early stages of development, with little documentation, and may not be fully functional). <item> A working procedure is given in <htmlurl url="http://download.sourceforge.net/pnm2ppa/color-calibrate-1.0.tar.gz" name="http://download.sourceforge.net/pnm2ppa/color-calibrate-1.0.tar.gz">, which is made available by Klamer Schutte. <bf>This is the method recommended by many users.</bf> </itemize> </article> �������������������������������������������������������������������������������������������������������������������������������������������pnm2ppa-1.13/docs/en/sgml/INSTALL.MANDRAKE.sgml�����������������������������������������������������0000644�0000764�0000764�00000005730�07501053375�015425� �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������<!doctype linuxdoc system> <article> <!-- Title information --> <title>PPA Printer-Support RPM Packages for MANDRAKE Linux distributions. <author>The pnm2ppa project team <htmlurl url="mailto:ppa-rpms@sourceforge.net" name="ppa-rpms@users.sourceforge.net"> <date>v0.2 June 11, 2002 <abstract> Information about using pnm2ppa with Mandrake.

However, a few legacy models, namely <itemize> <item> <em>DeskJet 710C Series</em>: HP DeskJet 710C, 712C <em>(discontinued)</em> <item> <em>DeskJet 720C Series</em>: HP DeskJet 720C, 722C <em>(discontinued)</em> <item> <em>DeskJet 820C Series</em>: HP DeskJet 820Cxi, 820Cse <em>(discontinued)</em> <item> <em>DeskJet 1000C Series</em>: HP DeskJet 1000Cxi, 1000Cse <em>(discontinued)</em> </itemize> feature "Host-based" printing, and use HP's proprietary PPA (<em>Printer Performance Architecture</em>) protocol, instead of PCL. The two models in each series are physically identical; they just came with different bundled Windows software. All PPA printers are now discontinued from HP's product lines, but may still be found as second-hand legacy items. PPA printers rely on software running on the host CPU to carry out the low-level processing of printer output that would be done by hardware in a standard PCL printer. The relation of PPA printers to PCL printers is analogous to the relation between "Winmodems" and true modems. Presumably, the idea at the time was that this would allow cheaper hardware to be used, but the decline in hardware prices probably meant that the savings were not significant, and PPA printing seems to have been abandoned. Unfortunately, HP only supplied Windows software drivers for PPA printers, and have indicated that it is unlikely that they will ever make the proprietary PPA specs public. This is apparently because of concerns that publication of the specs might reveal crucial details of HP's trade secrets about "color science" to competitors. (A secondary issue is that it is apparently possible to physically damage the printer by sending it bad sequences of PPA commands, which is not the case for PCL commands, and it seems that HP do not wish to take any responsibility for such damage by encouraging unofficial PPA programming.) In the past, Linux users often inadvertently purchased PPA DeskJet models, mistaking them for PCL3 DeskJets, which have traditionally been well-supported by Linux drivers. Fortunately, a reverse engineering effort, started in 1998 by Tim Norman, and continued by the <em>pnm2ppa</em> project at <htmlurl url="http://pnm2ppa.sourceforge.net" name="http://pnm2ppa.sourceforge.net">, and <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa"> has managed to produce drivers that provide basic printing functionality for these PPA printers under Linux and other Unices. While HP have recently begun to release their own Linux drivers for PCL3 DeskJets, they have not included drivers for their legacy PPA printers in this effort. The <tt>pnm2ppa</tt> driver has been stable since v1.04, released October 2000, with no known reproducible bugs, except that image printing quality was not so good. This version has been distributed with Red Hat, and other Linux distributions. v1.10, released July 2002, contains a lot of changes that improve image quality, in particular by improved bidirectional printing, and always printing black on top of color. A better improvement would be for someone to make a PPA backend to <htmlurl url="http://gimp-print.sourceforge.net" name="gimp-print">, using <tt>pnm2ppa</tt> as a guide for how to send data to PPA printers. But, since PPA printers are now "legacy" hardware, and <tt>pnm2ppa</tt> appears to work fine for most printing tasks, it is unlikely that any new developers will be interested in doing this, and there is currently no further development anticipated. The project is currently in "low-maintenance mode". <p> <bf> The pnm2ppa driver for color printing with PPA printers.</bf> Color printing with PPA printers is supported by the <em><tt>pnm2ppa</tt></em> driver which is the successor to the older black-and-white-only driver <htmlurl url="http://pnm2ppa.sourceforge.net/files/pbm2ppa-0.8.6.tar.gz" name="pbm2ppa-0.8.6"> developed by Tim Norman. <tt>pnm2ppa</tt> translates <em>portable anymap</em> (<em>pnm</em>) format images into a stream of PPA instructions which can be sent to the printer. In the driver name, "<em>pnm</em>" stands for the superset of <em>three</em> image formats: <em>ppm</em> (portable "pixmap" format for color images), <em>pgm</em> (portable "greymap" format for greyscale images), and <em>pbm</em> (portable "bitmap" format for black and white images). Ghostscript has a number of "output devices" that produce pnm format output from postscript or pdf input. These come in <em>plain</em> (text) and <em>raw</em> (binary) variants. While <tt>pnm2ppa</tt> can now interpret both plain and raw pnm formats, there is no point in using the inefficient plain formats: <em>always</em> use the "raw" output devices, which are: <itemize> <item><em>ppmraw</em> - raw pixmap format (color images); <item><em>pgmraw</em> - raw greymap format (greyscale images); <item><em> pbmraw</em> - raw bitmap format (black and white images); <item><em>pnmraw</em> - selects between ppm, pgm, and pbm raw formats; <item><em>pgnmraw</em> - selects between pgm and pbm raw formats. </itemize> The last two output devices are switches that try to analyze the image, and select an appropriate format; however, they are not recommended for routine use, as they may inconsistently choose the format. The <tt>ghostscript</tt> packages supplied with all recent Red Hat distributions provides all these devices. To see the list of available ghostscript output devices, type the command line <tscreen><verb> gs --help </verb></tscreen> if the required <tt>ppmraw</tt> or <tt>pbmraw</tt> devices are not shown, you will have to upgrade your version of ghostscript. The data must be streamed directly from ghostscript to <tt>pnm2ppa</tt> to the (local) printer without being stored in any intermediate file: one ppm-format (color) US Letter size page is represented by 3x5100x6600 Bytes (100MB) in binary format and four times this amount in text format. An example of a command line for printing a postscript file <tt>file.ps</tt> using <tt>gs</tt> (ghostscript) and <tt>pnm2ppa</tt> is <tscreen><verb> cat file.ps | gs -q -sDEVICE=ppmraw -r600 -sPAPERSIZE=letter -dNOPAUSE \ -sOutputFile=- - | pnm2ppa --eco -v 720 -i - -o - | lpr -l </verb></tscreen> (all on a single line). In this example the paper size is explicitly given to <tt>gs</tt> as <em>US Letter</em> (8.5"x11") size (<tt>letter</tt>); <tt>pnm2ppa</tt> no longer needs to be told what the paper size is, and will read it from the <tt>gs</tt> output (and check that it is a permitted size for the printer type). The <tt>pnm2ppa</tt> option <tt>--eco</tt> specifies "EconoFast" mode, for a lower quality output which uses less ink, and prints faster, and <tt>-v 720</tt> specifies the PPA printer as belonging to the DeskJet 720C series. <itemize> <item> <tt>pnm2ppa</tt> expects that the input resolution is 600dpi (or 300dpi if it is called with the <tt>pnm2ppa --dpi300 ...</tt>option). This corresponds to the <tt>gs -r600 ...</tt> or <tt>gs -r300 ... </tt> ghostscript options. If other higher/lower input resolutions are used, the size of the printed image will be larger/smaller, provided it is within the printer's allowed size range. </itemize> Obviously, it would be impractical to type such a command each time one wished to print something, and since RedHat 6.2, printfilter support for <tt>pnm2ppa</tt> is built into Red Hat's printer configuration scheme, so after configuration, the simple command <tscreen><verb> lpr file.ps </verb></tscreen> should successfully print a postscript file. However, in case you wish to check if something is misconfigured in the print filters, you can use a script like the above one to bypass them and check that the printer is working. <itemize> <item> <em> Also, if you wish to print to paper sizes supported by ghostscript, but not supported by the Red Hat Printer configuration utilities, you can use scripts like the one above. The HP 710C, 720C, and 820C series support paper sizes from 3"x3" to 8.5"x14", while the 1000C supports 4"x6" to 13"x19". </em> </itemize> <p> <bf> Available RPM packages.</bf> A RPM package for <tt>pnm2ppa</tt> is part of the Red Hat Linux distribution starting with Red Hat 6.2. You will also find a RPM package for the latest release of <tt>pnm2ppa</tt> at <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa">. The latest version at the time of writing is <tt>pnm2ppa-1.10-1rh7x.i386.rpm</tt>, and is built on Red Hat 7.3, or <tt>pnm2ppa-1.10-1rh62.i386.rpm</tt>, built on Red Hat 6.2. If you are running a different release of Red Hat (or a different Linux distribution) you may need to download and rebuild the source RPM <tt>pnm2ppa-1.10-1.src.rpm</tt> instead: <tscreen><verb> rpm --rebuild pnm2ppa-1.10-1.src.rpm </verb></tscreen> (You must be <tt>root</tt> to do this, and have the necessary compilers installed; on Red Hat, the rebuilt binary RPM will be created in the directory <tt>/usr/src/redhat/RPMS/i386/</tt>.) Red Hat 6.2 and later also includes support for configuring your printer to use <tt>pnm2ppa</tt>. (Information necessary for configuring <tt>pnm2ppa</tt> on older Red Hat releases has been removed from this document; for this, see the documentation that came with <tt>pnm2ppa-1.04</tt>, or update your RedHat distribution.) Note: If you are still using Red Hat 6.2, you may wish to update the print filter support for <tt>pnm2ppa</tt> that comes with it. The <tt>pnm2ppa-1.10-1rh62*</tt> RPM package supplies the necessary files that you can use. After installing this RPM, see <tt>/usr/lib/rhs/rhs-printfilters/README.ppa</tt> for details. <p> <bf> Installing the <tt>pnm2ppa</tt> RPM package and setting up the PPA printer.</bf> To install the RPM package, you must log in as the system administrator, <tt>root</tt>. Now begin the installation. First install the <tt>pnm2ppa</tt> RPM: <tscreen><verb> rpm -Uvh pnm2ppa-1.10-1*.i386.rpm </verb></tscreen> The <tt>pnm2ppa</tt> executable gets installed in <tt>/usr/bin/</tt>. The Linux kernel will be able to autodetect IEEE-1284 devices like PPA printers, provided they are attached to the parallel port with a bidirectional IEEE-1284 cable. (If your printer works under Windows, you have the correct cable.) A script <tt>detect_ppa</tt> is provided by the <tt>pnm2ppa</tt> RPM: just type <tscreen><verb> detect_ppa </verb></tscreen> to confirm that your Printer is found. A typical message from the printer, which will be displayed if autodetection is successful, is: <tscreen><verb> CLASS:PRINTER; MODEL:DESKJET 820C; MANUFACTURER:HEWLETT-PACKARD; DESCRIPTION:Hewlett-Packard DeskJet 820C; COMMAND SET:SCP,VLINK; </verb></tscreen> A list of PPA printers found, and the parallel ports to which they are attached, will also be shown. At this point it is useful to test that your printer is working, by printing a test page using the supplied script <tt>test_ppa</tt> which the RPM has installed. You will need to know your printer model (710, 712, 720, 722, 820, 1000), your paper size (letter, legal, a4) and the printer port the printer is attached to. If it is attached to the primary parallel port, this is (usually) <em><tt>/dev/lp0</tt></em>. Type <tscreen><verb> test_ppa </verb></tscreen> and give the details about printer model. papersize, and port number when prompted. You will then be asked whether to print a test page, an offset calibration page, or an alignment calibration page, etc. <itemize> <item> <em><em>Tip:</em> The </em><tt>test_ppa</tt><em> script does not use the Red Hat print filters, so it is useful when troubleshooting, for testing if any printing problems are associated with the basic printer installation, or with the configuration of the print filters.</em> </itemize> <bf> Configuring the print filters.</bf> Note: Red Hat 7.3 now features either CUPS or LPRng printer management. The configuration tools should be able to configure <tt>pnm2ppa</tt>, using the information about it taken from the Linux Printer Database. Apart from the addition of a new <tt>--dpi300</tt> option to accept 300dpi input (useful for printing PNM output from 300dpi scanners), there have been no changes in the pnm2ppa command line since the pnm2ppa-1.0 release, so the configuration scripts are stable. (They can only use the default 600dpi input mode.) Since Red Hat 7.1, there is a graphical printer configuration utility <tt>printconf-gui</tt>. In Red Hat 6.2 and 7.0, the older configuration utility called <tt>printtool</tt> is used. In either case, start the "<em>Red Hat Linux Print System Manager</em>" (as root) to configure the printer, either by clicking on the printer icon in Red Hat's "control-panel", or just typing <tscreen><verb> printtool </verb></tscreen> which also starts <tt>printconf-gui</tt> in the newer Red Hat releases. <p> <bf> Configuring the print filters with the Red Hat 6.2/7.0 printtool</bf> (Skip this section unless you are still using Red Hat 6.2 or 7.0) The following description is for the older <tt>printtool</tt> that is used by Red Hat 6.2/7.0. The printer configuration utility <tt>printconf-gui</tt> for Red Hat 7.1 and later is a little different, as it is based on the <em>foomatic</em> printer configuration database which contains entries for <tt>pnm2ppa</tt> (but not the older <tt>pbm2ppa</tt>). You should be able to easily figure out what to do: it can configure all <tt>pnm2ppa</tt> command-line options in the <em>Driver Options</em> screen. In the Red Hat 6.2/7.0 Print System Manager window, click on <em>Add</em>, then in the "Add a Printer Entry", select <em>Local Printer</em>, and click <em>Ok</em>. Hopefully, the port on which the printer is attached will be listed as "Detected" (<em>if not, fix the problem before continuing</em>, perhaps by adding the line "<tt>alias parport_lowlevel parport_pc</tt>" to <tt>/etc/conf.modules</tt>). You will now have to "<em>edit the local printer entry</em>" for the PPA printer. Click on <em>Select</em> to chose the "Input filter". The <em>Configure Filter</em> screen will open. Among the many printer entries in the list "<em>Printer Type</em>", you should find three entries <itemize> <item><bf>HP DeskJet 1000 series (PPA)</bf> (for 1000Cse, 1000Cxi models) <item><bf>HP DeskJet 710/720 series (PPA)</bf> (for 710C, 712C, 720C, 722C models) <item><bf>HP DeskJet 820 series (PPA)</bf> (for 820Cse, 820Cxi models) </itemize> Select the appropriate entry for your printer model. You will then be presented with various options: <itemize> <item> The <em>Driver Description</em> box contains information about the driver (you may have to use the scrollbar at the right of the box to read it all). <item>The <em>resolution</em> box shows a single resolution (600x600). There are no other choices. <item> The <em>Paper Size</em> box allows various choices (only <em>letter</em>, <em>legal</em>, and <em>a4</em> seem correspond to native paper sizes printed by the Red Hat print filters; the other choices, (a3, ledger, ...) appear to get resized by the print filters to print on US Letter size paper (?) ). (Other paper sizes cannot be selected this way, but you <em>can</em> print to any papersize, <em>if it supported by both ghostscript and the printer</em>, using a script, as described above, that bypasses the RedHat printfilters.) <item> The <em>Color Depth/ Uniprint Mode</em> box allows various selections of color and print quality (These are achieved by using various combinations of the <tt>pnm2ppa</tt> options <em>--eco</em> (EconoFast mode), <em>-p</em> (disable black ink cartridge) and <em>--bw</em> (black and white printing only), without direct intervention by the user.) The choices (in the most recent <tt>printerdb</tt> database) are: <itemize> <item> Black and White, econofast mode (<tt>--bw --eco</tt>) <item> Black and White, normal quality (<tt>--bw</tt>) <item> Color, econofast mode (<tt>--eco --fd</tt>) <item> Color, normal quality (<tt>--eco</tt>) <item> Color, high quality <item> Color, normal quality, black ink disabled (<tt>-p --eco</tt>) <item> Color, high quality, black ink disabled (<tt>-p --uni</tt>) </itemize> (These are the choices that will be presented by "official" <tt>rhs-printfilters-1.72</tt>; if you installed a <tt>pnm2ppa</tt> RPM package from <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="the SourceForge pnm2ppa site">, you may have a file <tt>/usr/lib/rhs/rhs-printfilters/README.ppa</tt> explaining how to modify earlier versions of <tt>rhs-printfilters</tt> to show these updated choices.) You may also see a choice to use the older "Legacy" driver <tt>pbm2ppa</tt> (black and white only); this is is stable but unmaintained; it may still be a useful alternative to <tt>pnm2ppa</tt> on older, slower systems with less available memory. <item> The three <em>Printing options</em> are not relevant here, and should <em>not</em> be selected. They are for direct printing of text (ascii) to non-postscript printers, but since the only way of printing text files with <tt>pnm2ppa</tt> is by first converting them to postscript(tm), this is <em>not</em> possible on the PPA printer. <itemize> <item> <em>It is important that the choice </em> "Fast text printing (non-PS printers only)"<em> is NOT selected, so that the print filters will convert text files to postscript before printing.</em> </itemize> <item>The <em>Margins</em> entries control the margins used when printing text files (these are instructions to the text-to-postscript conversion process). <item> The <em>Extra GS options</em> box is not only a place for adding options for ghostscript, but also for the PPA drivers. <em>Leave this box empty unless you know what you are doing</em>. As explained in the text in the Driver Description box (you did read it, didn't you ?), the entry should be in the format: <tscreen><verb> gs_options PPA ppa_options </verb></tscreen> Anything before the "<tt>PPA</tt>" is interpreted as a <tt>gs</tt> option, anything after it is interpreted as a <tt>ppa</tt> option. You can learn about <tt>pnm2ppa</tt> options by typing either "<tt>man pnm2ppa</tt>" or "<tt>pnm2ppa --help</tt>" at a command line (hopefully, these two sources of information will be consistent with each other!); </itemize> When you have made your choices, click on <em>Ok</em> to save your selections and close the "Configure Filter" screen, and then click on <em>OK</em> to close the "Edit Local Printer Entry" screen. You are now back in the "Red Hat Print System Manager" screen; highlight the printer you just configured, and, in the <em>Tests</em> menu, choose <em>Print Postscript test page</em> to print a test page using the Red Hat print filters. If this printed correctly, your print system is set up to use the PPA printer, just like any of the other printers that the Red Hat print filters support. <p> <bf> Configuring pnm2ppa.conf and calibrating the printer. </bf> A number of printer parameters are set to reasonable default values for each of the printer models, but you may wish to "fine tune" or calibrate your printer. The default values can be overridden by entries in the configuration files, which by default are <tt>/etc/pnm2ppa.conf</tt> and <tt>/etc/pbm2ppa.conf</tt>. At 600dpi, one pixel is 1/600 inch. The user-adjustable parameters are: <itemize> <item> <bf>verbose 1</bf> and <bf>silent 1</bf>. These control messages about progress and errors from <tt>pnm2ppa</tt>. By default, messages are sent to the system log <tt>/var/log/messages</tt>. The <tt>verbose 1</tt> keyword send copies to <tt>stderr</tt>, the standard error stream to the terminal. The <tt>silent 1</tt> keyword silences the stream of messages to the system log. <itemize> <item> <bf> The system log messages may be silenced in the default configuration file; switch off "silent" mode with "silent 0" for debugging printer problems (or use verbose mode).</bf> </itemize> <item> The <bf>version</bf> keyword can be used to specify the printer model as 710, 712, 720, 722, 820, or 1000. It is not needed if you use the RedHat printool to configure the printer. <item> <bf>xoffset</bf> and <bf>yoffset</bf>: the x-offset and y-offset (in pixels) of the printed image on the page, which should be chosen so the image is correctly centered on the paper. (These can also be set with the <tt> -x <xoff> </tt> and <tt> -y <yoff> </tt> options.) See <htmlurl url="./CALIBRATION.html" name="CALIBRATION.html"> (or CALIBRATION.txt) for more information. <item> <bf>topmargin</bf>, <bf>bottommargin</bf>, <bf>leftmargin</bf>, <bf>rightmargin</bf>: the four margins, which define the distances (in pixels) from the edges of the paper to the printed region; parts of the image that are outside these margins will not be printed. (These can also be set with the <tt> -t <top margin> </tt>, <tt> -b <bottom margin> </tt>, <tt> -l <left margin> </tt>, and <tt> -r <right margin> </tt> options.) <item> <bf>ColOffsX</bf> and <bf>ColOffsY</bf>: the x-offset and y-offset (in pixels) between the color image produced by the color ink printer head, and that produced by the black ink printer head. These should be recalibrated <bf> each time an ink cartridge is replaced</bf>. See <htmlurl url="./CALIBRATION.html" name="CALIBRATION.html"> (or CALIBRATION.txt) for more information. <item> <bf>blackshear</bf> and <bf>colorshear</bf>: these are x offsets between right-to-left and left-to-right sweeps of the print head, one for the black printing and one for the color printing. These provide sideways offsets (in pixels) of the right-to-left sweeps, that can be used to correct "shearing" when printing in modes that use bidirectional print head sweeps. <item><bf>unimode 1</bf> will make unidirectional print sweeps (left-to-right) the default, instead of bidirectional sweeps. The <tt>--uni</tt> and <tt>--bi</tt> options can control how a particular print run is printed. Unidirectional printing is only useful (it is slower) if there are issues of "shearing" in high quality image printing. <item> <bf>blackness</bf> : this takes values 0,1,2,3 or 4 drops of black ink per pixel, and controls black ink density in black-and-white and "text-like" black regions in color printing. At present, this has no effect on printing with the black ink cartridge disabled, or on black regions identified as "image-like". (This can also be set with the <tt> -B <n></tt> option, where <tt>n</tt> is the number of drops.) <item><bf>GammaR</bf>, <bf>GammaG</bf>, and <bf>GammaB</bf>: the are the three "gamma" parameters that define the standard color correction curves for red, green, and blue. Changing these will affect how colors appear (decreasing any Gamma enhaces the corresponding color). The Gamma values are specified as decimal numbers, with Gamma = 1.0 corresponding to no color correction. <item> Gamma values can also be specified using integer numbers <bf>RedGammaIdx</bf>, <bf>GreenGammaIdx</bf>, <bf>BlueGammaIdx</bf>; These are determined by a procedure discussed in <htmlurl url="./COLOR.html" name="COLOR.html"> or COLOR.txt, which involves printing a test page. The <bf>papersize</bf> keyword specifies the paper size used for this testpage, because it is produced by <tt>pnm2ppa</tt> without the input that usually specifies the page size. <item> The keywords <bf>black_ink 0</bf>, <bf>color_ink 0</bf>, <bf>cyan_ink 0</bf>, <bf>magenta_ink 0</bf>, and <bf>yellow_ink 0</bf> can be used to switch of the various inks; this can be useful in troubleshooting and debugging <tt>pnm2ppa</tt>. </itemize> Use <tt>test_ppa</tt> to print various test pages or calibration patterns to adjust the offsets. If you wish to specify these parameters using the command-line options described above, in Red Hat 6.2/7.0 some of them can be entered in the "extra GS options" box using the Print System Manager (<tt>printtool</tt>), as described above. In Red Hat 7.1 and later, all command-line options can be set using the new <tt>printconf-gui</tt> utility. <p> <bf> Utility programs for the printer.</bf> HP's Windows software provides a utility program that sends PPA commands to tell the printer to perform tasks like cleaning the printheads, etc. On Red Hat Linux, You can use <tt>test_ppa</tt> (which acts as a command-line front-end for <tt>calibrate_ppa</tt>) to print head-cleaning patterns. There is a graphical (gtk-based) tool written by Javier Sedano for creating a <tt>pnm2ppa.conf</tt> file and acting as a front end to <tt>calibrate_ppa</tt>. This is called <tt>ppaSet</tt>, and a beta version of it can be found in the same place as the <tt>pnm2ppa-1.10</tt> distribution at <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="http://sourceforge.net/projects/pnm2ppa"> There was also at one time a proposal to add support for PPA printers to the PUP (Printer Utility Program) utility, which is also a project at <htmlurl url="http://www.sourceforge.net/project/?group_id=1118" name="http://www.sourceforge.net">. However, as of the time of writing, no PUP support for PPA printers is available. <p> <bf>Troubleshooting</bf> The first thing to do is to look at the messages from <tt>pnm2ppa</tt> in the system log to see what is happening, whether <tt>pnm2ppa</tt> <bf>actually received any input</bf>, and if it was valid. <bf> (You may need to enable system log messages in <tt>/etc/pnm2ppa.conf</tt>, see above.)</bf> Maybe ghostscript failed to convert your postscript file into PNM format: in that case the system log reports <bf>"Fatal Error! Input image (pnm2ppa) is not a PNM image"</bf>. (note: when this occured, older versions of <tt>pnm2ppa</tt> reported <bf>"Input image is not a supported PNM format"</bf> which may have been confusing). This is because the input received by <tt>pnm2ppa</tt> was not a valid PNM image, but instead ghostscript failed to produce any PNM output at all, and its only output was probably just an error message. This is <em>not</em> a <tt>pnm2ppa</tt> problem! Here are suggestions for dealing with other problems that you may encounter. <itemize> <item><bf> Printing fails in the middle of a print run</bf>, perhaps when a figure embedded in the document is printing (in the latest <tt>pnm2ppa</tt> versions, printing finishes normally, but an incomplete document is printed). The system log reports that <tt>read_line</tt> could not read the image, and found EOF (end-of-file). This probably means that <tt>ghostscript</tt>'s "ppmraw" or "pgmraw" output device started correctly, but failed for some reason before finishing the image conversion from postscript to PNM format, usually leaving a core dump. (This has been seen to happen in ghostscript 5.10 ; upgrading to ghostscript 5.50 solved the problem.) If you cannot upgrade, try printing the document in black-and-white using the ghostscript "pbmraw" output device. <item> <bf>You printed an image file using a "high quality" printer setting, but it has visible horizontal lines on it </bf>and printing under Windows(tm) 9x doesn't show this effect (except in "economode"). These are probably "swath boundaries", showing the junction between different sweeps of the print head. Solution: using unidirectional printing (PPA option <tt>--uni</tt>, or <tt>unimode 1</tt> in <tt>/etc/pnm2ppa.conf</tt>) helps a little. <bf>this problem is fixed in the pnm2ppa-1.10 release</bf> <item> "<bf>Flashing light syndrome</bf> ". Your printer usually works, but you have found that some particular documents cause the printer to fail, and the lights on its panel start flashing rapidly in sequence. Solution, turn the printer off and back on again. This is not supposed to happen any more; if it happens reproducibly, contact the pnm2ppa developers, and offer to make the offending file available for testing and diagnosis of this problem. (Don't sent it to the Mailing List unless requested). Bug reports can be filed at <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="the SourceForge pnm2ppa site">. <item> <bf>You wish to print on envelopes or other non-standard media not supported by the print filters</bf>? Solution: if you can get Ghostscript (<tt>gs</tt>) to produce the correct image, and the paper size is in the range allowed by your printer, you should be able to do this with a script that bypasses the print filters, as described earlier in this document. <item> <bf>Colors look wrong, or do not match what the Windows(tm) 9x driver produces</bf>. Solution: check that your color ink cartridge is not running out of some ink color; if not, (a) adjust the "gamma" entries in <tt>/etc/pnm2ppa,conf</tt>, or (b) install a customized color calibration file <tt>/etc/pnm2ppa.gamma</tt>.

Topics include choosing between transmitting PPA or PostScript across the network, Windows and Linux/Unix Hosts, Windows and Linux/Unix Clients, and emulating a PostScript printer on Windows. (Updated for pnm2ppa-1.04 and later.) </abstract> <!-- Begin the document --> <toc> <sect> Networking HP DeskJet PPA printers with SAMBA <p> <sect1> Overview of PPA printers. <p> The HP DeskJet 710/712C, 720/722C, 820Cse/820Cxi and 1000Cse/1000Cxi printers are "Winprinters" which are designed only for use with MS Windows operating systems. HP supplies Windows-only software that processes the input data into the proprietary and unpublished PPA ("Printer Performance Architecture") protocol. HP states that these printers are <bf>not supported as networked printers</bf>, but they in fact function correctly as shared (SMB) printers under MS Windows. In this document, the <bf>Host</bf> is the computer to which the PPA printer is physically connected, and the <bf>Clients</bf> are other computers on the network that wish to print documents on the PPA printer. In the Windows printing system, separate copies of the HP PPA printer drivers are installed on each Client, and are run on the Client to produce PPA output that is sent over the network to be spooled on the Host to which the printer is attached. HP's drivers are only supplied for Windows systems. The independently-produced <htmlurl url="http://sourceforge.net/projects/pnm2ppa" name="pnm2ppa"> driver runs on Linux, some other Unix systems, and BeOS. This document describes various tested strategies for using <tt>pnm2ppa</tt> and the <htmlurl url="http://www.samba.org" name="samba"> suite of SMB tools to allow the PPA printer to be attached to a non-Windows host on a (TCP-based) SMB network, or to allow non-Windows Clients to receive printing services from a Host on the network. <sect1> Choice of protocol for sending over the network. <p> There are <bf>two</bf> possible ways to send printer data from a Client to the printer Host over the network. <itemize> <item> as <bf>PPA data</bf>, created by a driver on the Client. This is what happens when using conventional printer sharing on Windows. <item> as <bf>PostScript data</bf>, created on the Client, which is then translated into PPA instructions by drivers running on the printer Host. </itemize> Since PPA data is rather large, the first method involves sending larger amounts of data over the network, which may be why HP do not officially support PPA DeskJets as networked printers. It also requires that PPA drivers are installed on the Client. The Host to which the printer is attached can thus provide <bf>two</bf> classes of printing services: <itemize> <item> <bf>PPA printing services:</bf> the Host accepts PPA-format printing jobs created on the Clients either with HP's native PPA drivers (Windows Clients) or <tt>pnm2ppa</tt> (Unix/Linux/BeOS Clients); <item> <bf>PostScript printing services:</bf> the Host accepts PostScript-format printing jobs created on any postscript-capable Client, and converts them to PPA format using either HP's native PPA drivers (Windows Host) or <tt>pnm2ppa</tt> (Unix/Linux/BeOS Host); </itemize> It is useful to set up the Host to offer <bf>both types</bf> of service, sharing a common spooling system. <sect> Configuring the Printer Host. <p> <sect1> Configuring a Linux/Unix Host to share a PPA printer using Samba. <p> It is assumed that <tt>pnm2ppa</tt> is installed and working to provide local printing services on the Host, and that <tt>lpr</tt> will invoke a full set of print filters, as (e.g.) in Red Hat 6.2. The PPA printer is installed with the printer name <tt>lp</tt>, and <tt>samba</tt> is assumed to be installed. General Samba configuration issues involving security levels, network password, etc, are outside the scope of this document (see the SMB-HOWTO). You must log in as <tt>root</tt> to configure Samba. Here is a sample entry setting up two public printer shares in the Host's <tt>/etc/smb.conf</tt> file. The printer HP722C-PPA is for printing by a Client that sends PPA output from <tt>pnm2ppa</tt> or the HP drivers across the network, and HP722-PS is for Clients that produce PostScript output: <tscreen><verb> [HP722C-PPA] comment = HP 722C printer on Linux (PPA input) path = /var/tmp printer name = lp writable = yes public = yes printable = yes print command = lpr -l -r -h -P %p %s [HP722C-PS] comment = HP 722C printer on Linux (Postscript input) path = /var/tmp printer name = lp writable = yes public = yes printable = yes print command = lpr -r -h -P %p %s </verb></tscreen> The only differences besides the names are that the print command for HP722-PPA uses the "<tt> -l </tt>" "pass-through" option so print filters are not applied. The <tt>path</tt> entry uses <tt>/var/tmp</tt> because this is (presumably) a world-readable and -writable area for temporary files. After editing <tt>/etc/smb.conf</tt> to include these entries, save it, and test its syntax with Samba's <tt>testparm</tt> utility. Then restart samba (run "<tt>/etc/rc.d/init.d/smb restart</tt>" on Red Hat). <sect1> Configuring a Windows Host to share a PPA printer with non-Windows Clients. <p> The Host is assumed to be a Window 98 system, and the PPA printer is assumed to be a HP722C installed with the native HP PPA drivers supplied on HP's installation CD. Some details may vary on other Windows versions. First set up a shared printer that can accept PPA input from both networked Windows Clients, and from networked non-Windows Clients that use <tt>pnm2ppa</tt>. <itemize> <item><bf>IMPORTANT!</bf>: A PPA printer attached to a Windows Host shared with a Client running pnm2ppa has the following limitation: <itemize> <item> <bf>Bi-Directional communication between the Windows Host and the printer must be disabled.</bf> </itemize> If it is not done, <bf>a General Protection Fault</bf> will usually occur on the Windows Host when pnm2ppa sends output to the shared printer. (A "Hpfbkg06" error occurs, and the printer becomes nonfunctional until the Windows system is rebooted.) Disabling bi-directional communication appears to be a minor inconvenience: according to HP, the print quality is unaffected, but the "advanced features of the Status Monitor" will no longer send reminders to align the print cartridges after a new cartridge is installed, or send error messages associated with the ink cartridges or the banner lever. </itemize> You may be able to avoid disabling bi-directional communication by using an emulated Postscript printer to serve non-Windows Clients <bf>without</bf> using <tt>pnm2ppa</tt> (see below). To turn off bi-directional communication between the Windows Host and the printer, open the <bf>Settings/Printers</bf> folder, then right-click on the printer icon, and open the <bf>Properties</bf> dialog. Select the <bf>Details</bf> tab, and click on <bf>Spool Settings</bf>, then choose the setting "<bf>Disable bi-directional support for this printer</bf>". If you have any difficulties, try rebooting Windows after the change, or see HP's support document <htmlurl url="http://www.hp.com/cposupport/printers/support_doc/bpd06455.html" name="http://www.hp.com/cposupport/printers/support_doc/bpd06455.html"> about disabling bi-directional communication. To set up the Host to share the printer, right-click on its icon in the <bf>Settings/Printers</bf> folder, and select <bf>Sharing</bf>, then assign it a Share Name like HP722C-PPA , and enter a Comment Line like "HP 722C printer on Windows 98 (PPA input)". You may now also wish to set up an emulated Postscript printer that accepts Postscript input from the Client, and prints it using HP's PPA drivers <bf>running on the Host, instead of on the Client.</bf> See the section <htmlurl url="PPA_networking-4.html" name="Emulating a PostScript printer on a Windows Host"> If you have installed and successfully tested the emulated printer, set it up for sharing on the network. Right-click on its icon in the <bf>Settings/Printers</bf> folder, and select <bf>Sharing</bf>, then assign it a Share Name like HP722C-PS, and enter a Comment Line like "HP 722C printer on Windows 98 (PostScript input)". The emulated printer will appear like a Postscript printer to the Clients. If it provides acceptable printing services to the non-Windows clients, you will not need to connect <tt>pnm2ppa</tt> printers to HP722C-PPA, and will be able to re-enable bi-directional communication between the HP drivers and the printer. (However, the extra processing involved in the emulation may be unacceptably slow, or turn out to use too much of the host's CPU) <sect> Configuring the Printing Clients. <p> <sect1> Setting up Printing from a Windows Client. <p> Open the <bf>Settings/Printers</bf> folder, and start the <bf>Add Printer</bf> Wizard. Choose to add a Network Printer, and browse the network to find the Printer Shares you configured on the host (e.g., HP722C-PPA and HP722C-PS). If they are not visible, either the Host or the network is not properly configured. Correct the problem before proceding. Normally, you will probably want to use the native Windows HP PPA drivers, so select the printer Share that accepts PPA input (e.g., HP722C-PPA). If the Host is a Windows Host, it will provide the drivers over the network, otherwise you will have to find the printer in the list of available HP Printer drivers, or click on <bf>Have Disk</bf> and install them from HP's installation CD. You then get a chance to change the name with which the printer will be known on the Client. Finally, you should choose to print a test page. You might instead (or also) want to set up printing services using the Printer Share that accepts Postscript (e.g., HP722C-PS). In that case, if the Host is not a Windows Host, choose a "generic" PostScript printer like the Apple LaserWriter II NT or the Digital turboPrintServer 20/Net. If the test page prints sucessfully, you are finished! <sect1> Setting up Printing from a Linux/Unix Samba Client <p> First examine the network by opening a terminal window and using the command <tscreen><verb> smbclient -L hostname </verb></tscreen> (where "hostname" should be replaced by the network name of the Host to which the printer is attached). This will list the SMB services provided by that Host. (Alternatively, your system may have some graphical front-end to <tt>smbclient</tt> that allows you to inspect the network.) The list should include the Printer Share(s) you configured on the Host (e.g., HP722C-PPA and HP722C-PS). If these are absent, you must first identify and correct the problem. You must now configure the printer. The details of how to do this will vary between Linux/Unix distributions, but there will probably be support for network printing using Samba. If the Printer Share you wish to use is intended to accept PPA input (e.g., HP722C-PPA), configure the Client to use the <tt>pnm2ppa</tt> driver. If it is intended to accept PostScript input (e.g., HP722C-PS), configure the Client to print to a PostScript printer. You may wish to configure both types of printers, and experiment to see which provides the best printing services on your network. See the SMB-HOWTO documentation for more information. <sect> Emulating a PostScript printer on a Windows Host. <p> If you do not have commercial PostScript emulation software for Windows that will work with your HP PPA DeskJet (the author is unaware of any such software that supports PPA printers), you can use <bf>Ghostscript</bf> together with HP's native Windows drivers. <sect1> Installing Ghostscript as the emulation software. <p> From the Ghostscript home page <htmlurl url="http://www.cs.wisc.edu/~ghost/" name="http://www.cs.wisc.edu/~ghost/"> download and install (in this order) the Windows packages of <itemize> <item> <bf>Ghostscript</bf> (PostScript Emulation Software). <item> <bf>GSview</bf> (Ghostscript previewer, provides <tt>gsprint</tt>). <item> <bf>RedMon</bf> (printer port redirection utility). </itemize> (Install these using their <tt>setup.exe</tt> installation tools, and do not manually set up any configuration files for <tt>gsprint</tt> or <tt>RedMon</tt>.) You must now follow the detailed instructions below, and use the Windows "Add Printer Wizard" to add a postscript printer, and then configure it to use the <tt>gsprint</tt> utility that comes with GSview, and redirect the output to your HP PPA DeskJet using the <tt>RedMon</tt> utility. <sect1> Adding the fictitious Postscript printer. <p> In the following, I assume your printer is a HP DeskJet 722C, and is installed with its native Windows Drivers as a printer called "HP DeskJet 720C Series". Change printer name entries below as appropriate for your printer model. The following instructions are tested on Windows 98, and may differ on other Windows variants. Open the <bf>Settings/Printers</bf> folder. First check that the HP PPA Deskjet is correctly installed, using HP's native Windows drivers. Right-click on its icon, and select its <bf>Properties</bf> dialog. The <bf>General Properties</bf> screen will open. This shows the <bf>exact name</bf> that the printer was given when it was installed. Make a note of it, and use the <bf>Print Test Page</bf> button to confirm that the printer is working. (The "Printer name:" line on the test page will also show the <bf>exact name</bf> of the HP PPA Deskjet that you will need to use when configuring the emulated postscript printer below). When you are done, click on <bf>OK</bf> to close the dialog. Now start the <bf>Add Printer</bf> "Wizard". Make the choices: <itemize> <item> install a <bf>local printer</bf> <item> select a PostScript printer from the list of printers; (e.g., one of the <bf>Apple LaserWriter</bf> models: the Laserwriter II NT is known to work; <bf>Digital PrintServer</bf> models such as the turboPrintServer 20/Net have also been recommended). This will provide a suitable postscript driver. <item> From the list of Available Ports, choose "<bf>FILE: Creates a file on disk</bf>" (you will change this after the printer is installed) <item> set as default printer?: <bf>NO</bf> <item> Print test page?: <bf>NO</bf> </itemize> <sect1>Redirecting the output to the PPA printer. <p> After the printer has been installed, right-click on its icon, and rename it to something like, e.g., "Ghostscript+HP722C". Then right click again and open its <bf>Properties</bf> dialog. On the <bf>General</bf> tab screen, enter something informative in the <bf>Comment</bf> box, such as " Emulated Postscript printer; output redirected to a HP722C DeskJet printer" (optional). Next select the <bf>Details</bf> tab. The box "<bf>Print using the following driver:</bf>" should show the Postscript driver you selected (e.g., Apple LaserWriter II NT). <itemize> <item> Click on <bf>Add Port</bf>. Select <bf>other</bf>, then <bf> Redirected Port</bf>, which should be available if <tt>RedMon</tt> was correctly installed, and click on <bf>OK</bf> to accept these settings and close the Add Port dialog. On the <bf>Details</bf> tab screen, The box "<bf>Print to the following port:</bf>" should now show a redirected port such as "<tt>RPT1 [Redirected Port]</tt>". <item> Click on <bf>Port Settings</bf>. <itemize> <item>In the box "<bf>Redirect port to the program:</bf>", enter the path to the <tt>gsprint</tt> program. (If you accepted the defaults when installing it, this may be <tt>C:\Ghostgum\gsview\gsprint.exe</tt>; you may search for it by clicking on <bf>Browse</bf>). <item>In the box "<bf>arguments for this program are:</bf>" enter the arguments to be passed to the <tt>gsprint</tt> program (there is a document <tt>gsprint.htm</tt> with more details of these in the folder containing <tt>gsprint.exe</tt>). Suggested arguments are: <tscreen><verb> -printer "HP DeskJet 720C Series" -color - </verb></tscreen> Replace "HP DeskJet 720C Series" by the (quoted) <bf>exact name</bf> of the HP PPA DeskJet printer that you made a note of earlier. <bf>(If you do not copy this name exactly, including any capitalization or spaces, things may not work!)</bf> The <tt>-color</tt> argument is needed to enable color printing; (Whether you actually get color printing will depend on the local settings of the "HP DeskJet 720C Series" printer that really prints the document.) The final "<tt> - </tt>" is <bf>required</bf>: without it, the output of <tt>gsprint</tt> will not get redirected to the printer. <item>The box "<bf>Output</bf>" should show "<bf>Program handles output</bf>". <item>In the box "<bf>Run</bf>", select "<bf>hidden</bf>". <item>The box "<bf>Shutdown delay</bf>" will say "300 seconds". Print jobs for which processing by <tt>gsprint</tt> takes longer than this will be terminated, to avoid blocking the printer spool queue. Increase this limit if necessary. </itemize> Now click on <bf>OK</bf> to close the Port Settings dialog. <item> Click on <bf>Spool Settings</bf>, and select "<bf>Disable bi-directional support for this printer</bf>", and click <bf>OK</bf>. </itemize> Finally, again select the <bf>General</bf> tab, and test the installation by clicking on "<bf>Print a test page</bf>". If it works, you are finished setting up Postscript emulation. Click <bf>OK</bf> to exit the Printer Properties dialog. (If you have problems, first check that you made the correct entries in the Printer Properties dialogs, <bf>especially check that you did not make any typing errors in the exact name for the PPA DeskJet printer in the</bf> <tt>gsprint</tt><bf> arguments box</bf>, which must correspond exactly to the "Printer name" given to the HP PPA printer). If the problems persist, you might get guidance from the gsprint and RedMon documentation; look in the folders where these were installed.) You now have a working emulated "Postscript printer" that can now be shared over a network.

PPA Printer calibration for pnm2ppa

The pnm2ppa project team ppa-rpms@users.sourceforge.net

v0.4, October 28, 2000

Information and instructions for printer calibration using pnm2ppa. http://sourceforge.net/projects/pnm2ppa (Updated for pnm2ppa-1.02 and later.)

Overview of Printer Calibration.

There are three main tasks you may need to carry out to fine-tune your PPA printer:

These instructions assume that you are already able to print postscript files with your PPA printer. If your print filters are properly configured, something like "lpr test.ps" will successfully invoke ghostscript and pnm2ppa to print the postscript file test.ps. Alternatively, you may be using shell scripts like "lprbw", "lprcolor" and "lpreco" supplied with the pnm2ppa source code, and modified by you for your defaults; you may also have defined special printing devices in /etc/printcap, e.g. a "coloreco" device so you print with lpr -P coloreco test.ps. These details vary with the operating system and distribution you use.

(1) Centering the printed page on the paper.

This is done by adjusting the x-offset and y-offset parameters xoffset and yoffset in the pnm2ppa configuration file (usually /etc/pnm2ppa.conf). The parameters are given in units of 1/600 inch; increasing xoffset moves the image to the right, and increasing yoffset moves it downwards. These offsets now have default values defined for each printer model, and you will probably not need to adjust them. Uncomment and make small adjustments to the default values for these in the configuration file, until the printout is satisfactory. (You can also use the '-x' and '-y' command-line parameters.)

There are two ways to check the offsets.

The "calibrate_ppa" program is a stand-alone program distributed with pnm2ppa which creates various test patterns in the raw pixmap format accepted by pnm2ppa. (The three paper sizes, US Letter, US Legal, and A4, are supported). If your paper size is A4, and your printer filter accepts the "-l" (direct output) option to lpr, the command to run is: 

 calibrate_ppa -s a4  --center  | pnm2ppa --bw  -i -  -o - | lpr -l
(Substitute "letter" or "legal" for "a4" to change the papersize; if no paper size is specified, it is assumed to be letter.)

If "lpr -l" is not valid, you need to know which port your printer is attached to. Assuming it is /dev/lp0, the above command becomes calibrate_ppa -s a4 --center | pnm2ppa --bw -i - -o /dev/lp0.

The pattern shows distances from the edge of the printed page in units of 50 dots (1/12 inch), and diagonal lines that should point to the corners. Change xoffset and yoffset in the configuration file (usually /etc/pnm2ppa.conf to center the pattern. The configuration file is supplied with commented-out entries like #xoffset 160 showing the default value. Remove the "#" to activate the entry.

In Red Hat or Mandrake Linux distributions, a suitable test page is /usr/lib/rhs/rhs-printfilters/testpage.ps (US Letter paper) or /usr/lib/rhs/rhs-printfilters/testpage-a4.ps (A4 paper). (If these are not available, similar test pages are supplied in the pnm2ppa source distribution.) These pages have margins drawn at standard distances from the edges of the paper, and can also be used to check the centering, but are not as accurate

(2) Calibrating the X and Y Color Head Offsets.

The color ink offsets now have to be calibrated with respect to the black ink. Because the relative position of the two ink cartridges can move slightly, this must be done whenever an ink cartridge is removed and replaced.

To print an alignment calibration pattern on a4 paper, run 

calibrate_ppa -s a4  --align | pnm2ppa --fd  -i - -o - | lpr -l

On the printed page, there are four alignment patterns, corresponding to configuration file parameters ColOffsX, ColOffsY, colorshear and blackshear. The central alignment patterns, labelled "0" should be perfectly aligned. If they are not, first correct the shearing patterns, (see below). Then identify the best-aligned ColOffsX and ColOffsY patterns, and add or subtract the positive or negative number below the pattern from the value in the configuration file.

Check the result by printing the alignment test pattern: 

calibrate_ppa  --test | pnm2ppa -fd  -i - -o - | lpr -l
The lines in the cross and square should be perfectly straight now.

The calibration can also be done by printing the test page test.ps (found in the tarball pnm2ppa-1.0.tar.gz; or installed with the pnm2ppa documentation. (This is often in /usr/doc/pnm2ppa*/.)

On the printout you see several images:

If these items do NOT line up, you should take the following steps:

Now you can print test.ps again to see whether this procedure worked.

Shearing adjustments

If bidirectional printing causes "shearing" of vertical lines (horizontal offsets of those parts of the line printed by left-to-right print-head sweeps relative to those printed on right-to-left sweeps) you can make small adjustments (in 1/600 inch) units using the blackshear and colorshear parameters in the configuration file. You can also suppress bidirectional printing with a unimode 1 configuration file entry.

The third and fourth lines on the color head offset calibration page (see above) correspond to color and black print head shearing corrections. If the central alignment patterns (labeled "0") are not aligned, add or subtract the positive or negative number below the best-aligned pattern from the colorshear and blackshear values in the configuration file.

Cleaning the Print Heads

You can use calibrate_ppa to clean the print heads by printing patterns that exercise all the ink nozzles: 

calibrate_ppa  --clean | pnm2ppa -p   -i - -o - | lpr -l
calibrate_ppa  --clean | pnm2ppa --bw  -i - -o - | lpr -l
The first of these commands prints a cleaning pattern with colored ink, the second uses black ink.

Other adjustments

The parameter blackness adjusts the number of black ink drops printed per pixel. It takes values 1, 2, 3, or 4 (2 is the default). Other values, like 0, suppress black ink.

Inks can also be suppressed by configuration file entries black_ink 0, color_ink 0, cyan_ink 0, magenta_ink 0, or yellow_ink 0. These are mainly useful for debugging the printer driver.

Overview of Printer Calibration. There are three main tasks you may need to carry out to fine-tune your PPA printer: o Adjust the x-offset and y-offset to correctly center the printed page on the paper o Adjust the relative offsets between black and colored ink printing - this should be done each time you replace an ink cartridge. o Match the colors of printed images to some other output device - this is color correction and is described in COLOR.html (or COLOR.txt). These instructions assume that you are already able to print postscript files with your PPA printer. If your print filters are properly configured, something like "lpr test.ps" will successfully invoke ghostscript and pnm2ppa to print the postscript file test.ps. Alternatively, you may be using shell scripts like "lprbw", "lprcolor" and "lpreco" supplied with the pnm2ppa source code, and modified by you for your defaults; you may also have defined special printing devices in /etc/printcap, e.g. a "coloreco" device so you print with lpr -P coloreco test.ps. These details vary with the operating system and distribution you use. (1) Centering the printed page on the paper. This is done by adjusting the x-offset and y-offset parameters xoffset and yoffset in the pnm2ppa configuration file (usually /etc/pnm2ppa.conf). The parameters are given in units of 1/600 inch; increasing xoffset moves the image to the right, and increasing yoffset moves it downwards. These offsets now have default values defined for each printer model, and you will probably not need to adjust them. Uncomment and make small adjustments to the default values for these in the configuration file, until the printout is satisfactory. (You can also use the '-x' and '-y' command-line parameters.) There are two ways to check the offsets. o either using the "calibrate_ppa" program. o or printing a suitable test page. The "calibrate_ppa" program is a stand-alone program distributed with pnm2ppa which creates various test patterns in the raw pixmap format accepted by pnm2ppa. (The three paper sizes, US Letter, US Legal, and A4, are supported). If your paper size is A4, and your printer filter accepts the "-l" (direct output) option to lpr, the command to run is: calibrate_ppa -s a4 --center | pnm2ppa --bw -i - -o - | lpr -l (Substitute "letter" or "legal" for "a4" to change the papersize; if no paper size is specified, it is assumed to be letter.) If "lpr -l" is not valid, you need to know which port your printer is attached to. Assuming it is /dev/lp0, the above command becomes calibrate_ppa -s a4 --center | pnm2ppa --bw -i - -o /dev/lp0. The pattern shows distances from the edge of the printed page in units of 50 dots (1/12 inch), and diagonal lines that should point to the corners. Change xoffset and yoffset in the configuration file (usually /etc/pnm2ppa.conf to center the pattern. The configuration file is supplied with commented-out entries like #xoffset 160 showing the default value. Remove the "#" to activate the entry. In Red Hat or Mandrake Linux distributions, a suitable test page is /usr/lib/rhs/rhs-printfilters/testpage.ps (US Letter paper) or /usr/lib/rhs/rhs-printfilters/testpage-a4.ps (A4 paper). (If these are not available, similar test pages are supplied in the pnm2ppa source distribution.) These pages have margins drawn at standard distances from the edges of the paper, and can also be used to check the centering, but are not as accurate (2) Calibrating the X and Y Color Head Offsets. The color ink offsets now have to be calibrated with respect to the black ink. Because the relative position of the two ink cartridges can move slightly, this must be done whenever an ink cartridge is removed and replaced. To print an alignment calibration pattern on a4 paper, run calibrate_ppa -s a4 --align | pnm2ppa --fd -i - -o - | lpr -l On the printed page, there are four alignment patterns, corresponding to configuration file parameters ColOffsX, ColOffsY, colorshear and blackshear. The central alignment patterns, labelled "0" should be perfectly aligned. If they are not, first correct the shearing patterns, (see below). Then identify the best-aligned ColOffsX and ColOffsY patterns, and add or subtract the positive or negative number below the pattern from the value in the configuration file. Check the result by printing the alignment test pattern: calibrate_ppa --test | pnm2ppa -fd -i - -o - | lpr -l The lines in the cross and square should be perfectly straight now. The calibration can also be done by printing the test page test.ps (found in the tarball pnm2ppa-1.0.tar.gz; or installed with the pnm2ppa documentation. (This is often in /usr/doc/pnm2ppa*/.) On the printout you see several images: o top left, you see a square with both black and colored items. These should align correctly, or you have to change your settings. o You see a large vertical bar, and also a horizontal bar. On the sides of the vertical bar there are a blue and a green line. These should align with the 0 mark. o You also see a small vertical, and horizontal, bar, with a red bar on its side. If these items do NOT line up, you should take the following steps: o (1) take for the large bar the number of the tickmark just smaller than the place where the green and blue lines point to. The minor tick marks are 25 points. o (2) To this number, add the number of the tick mark at which a red tick mark exactly lines up. This might not work if the offsets are way off; in that case, apply the correction of step 1, and print again. o (3) Add the horizontal offset to the value of ColOffsX, and the vertical offset to the value of ColOffsY in the configuration file. Now you can print test.ps again to see whether this procedure worked. Shearing adjustments If bidirectional printing causes "shearing" of vertical lines (horizontal offsets of those parts of the line printed by left-to- right print-head sweeps relative to those printed on right-to-left sweeps) you can make small adjustments (in 1/600 inch) units using the blackshear and colorshear parameters in the configuration file. You can also suppress bidirectional printing with a unimode 1 configuration file entry. The third and fourth lines on the color head offset calibration page (see above) correspond to color and black print head shearing corrections. If the central alignment patterns (labeled "0") are not aligned, add or subtract the positive or negative number below the best-aligned pattern from the colorshear and blackshear values in the configuration file. Cleaning the Print Heads You can use calibrate_ppa to clean the print heads by printing patterns that exercise all the ink nozzles: calibrate_ppa --clean | pnm2ppa -p -i - -o - | lpr -l calibrate_ppa --clean | pnm2ppa --bw -i - -o - | lpr -l The first of these commands prints a cleaning pattern with colored ink, the second uses black ink. Other adjustments The parameter blackness adjusts the number of black ink drops printed per pixel. It takes values 1, 2, 3, or 4 (2 is the default). Other values, like 0, suppress black ink. Inks can also be suppressed by configuration file entries black_ink 0, color_ink 0, cyan_ink 0, magenta_ink 0, or yellow_ink 0.

Color correction for pnm2ppa

The pnm2ppa project team ppa-rpms@users.sourceforge.net

Information and instructions for color correction of pnm2ppa color printing. http://sourceforge.net/projects/pnm2ppa (Updated for pnm2ppa-1.0 and later.)

Overview of Color correction.

Color Pixmap input to pnm2ppa (ppm format, produced by the ghostscript output devices ppmraw or ppm) specifies the color of a pixel as three coordinates (Red, Green, Blue) in the range 0-255. The program pnm2ppa converts these to relative amounts of Cyan, Magenta and Yellow ink drops printed on the page.

Color correction allows the user to attempt to match the printed colors to some reference colors, such as those displayed on the terminal, or those printed on a different printer, or those printed on the same printer with a different driver (such as the Win9x drivers supplied by HP with their PPA printers).

The color output from pnm2ppa can be controlled in two ways:

pnm2ppa will carry out "color correction", unless it is called with the --noGamma command line option. However, unless you set up a color correction scheme, the default color correction does not change any colors.

Color correction is specified by three color intensity functions (curves), one for each of Red, Green, and Blue. In their simplest form, these curves have a standard form controlled by a single "gamma" parameter such as GammaR. The more sophisticated correction, in the file pnm2ppa.gamma, specifies these curves more generally as a table of numbers that translate each possible color intensity value to a new value.

Note that, in principle, different color corrections are needed for different print quality settings, and for different brands and qualities of paper!

At present the methods for constructing a color correction for pnm2ppa are not very user-friendly. If you can improve them, please help!.

Color correction with "gamma" values in the configuration file.

The PixMap (ppa) format specifies colors by an intensity for each primary color, Red, Green and Blue, in the range 0-255, so (0,0,0) is black, and (255,255,255) is white. The standard color intensity enhancement function replaces the ppm intensity i of each primary color by Enh(i) which is the closest integer to ( i / 256) raised to the power Gamma, times 256.

You can specify the Gamma values in the configuration file as decimal numbers GammaR, GammaG, GammaB, but how do you find out what values to choose?. Perhaps by experimenting with changing the Gamma values.

A source of information on Gamma color correction is www.cgsd.com/papers/gamma.html

One method for constructing a Gamma correction has been built into pnm2ppa, but it wastes quite a lot of ink, and many users find it less effective than producing a customized color correction curve as described in the next section.

You must first use pnm2ppa to print a color test page, and then generate a file gamma.ppm to compare to it. To do this, type 

pnm2ppa -g -i - -o /dev/lp0
(replace /dev/lp0 by whatever printer device your PPA printer uses, or use ... -o - | lpr -l , etc.). Note also that as pnm2ppa is not receiving any ghostscript input to tell it the paper size, this must be correctly specified by a configuration file entry or, e.g., a -s a4 option, if the default US Letter paper is not being used. This procedure will print a color calibration page.

The printed output is an array of sets of three colored bands, red, blue and green, each of which increases in brightness from left to right. The topmost set of bands should be referrred to as bands "0", the next ones as "1", etc.

Next, run the extra program calibrate_ppa which will produce a (large, 10MB) PixMap (ppm) file: 

calibrate_ppa -g -o gamma.ppm
This will produce the PixMap file as gamma.ppm in the current directory.

To color-correct the printer so that its colors match those on the terminal screen, you should now attempt to view the file gamma.ppm using some application (such as the GNU image manipulation program gimp, or xv) that can view .ppm files. For each color, identify the printed band (0, 1, 2, ... etc) that most closely corresponds to the brightness profile shown on the screen. The default values are now: 

RedGammaIdx 0
GreenGammaIdx 0
BlueGammaIdx 0
(i.e., no color correction). Enter your modified values for these in the pnm2ppa configuration file (usually /etc/pnm2ppa.conf).

The actual Gamma value is then 1.0 - 0.033*(Color)GammaIdx ;

To color-correct with respect to another printer (or the Win9x drivers), you must manage to print gamma.ppm on that other device, then make the comparison. (Or print the output of pnm2ppa -g on that device; the top line is the same uncorrected color data as gamma.ppm.)

Color correction using a "gamma file".

A "gamma correction file" is a binary file containing 3 x 256 numbers, which are lookup tables of corrected red green and blue color intensities.

The program pnm2ppa will use a default correction file /etc/pnm2ppa.gamma if it exists, unless the --noGamma option is used. The default correction file location can be changed by using the pnm2ppa option -F gammafile , where "gammafile" is the name (including the full path) of the gamma correction file to be used.

Currently, there are two available tools for constructing a gamma correction file:

This is the method recommended by many users. pnm2ppa-1.13/docs/en/CREDITS0000644000076400007640000000173707072327606012337 00000000000000CREDITS ------- This project would not be where it is without the help of the following people (in firstname alphabetical order): Andrew van der Stock - rampant featuritis and general code enhancer since Sept 1999 Ben Boule - first contacted me about the 720 series and helped with testing Duncan Haldane - Redhat doco, fixes, RH print filter, RPM maintainer; extensive debugging of code, Jan-April 2000, Giorgio Marzano - heaps of quality bug fixes and features since May 1999 Javier Sandano - hp-ppa-printing-howto Jim Peterson - spent hours modifying the code for the 720 and adding lots of features, including all the configurability options.

Overview -------- This file contains some quick notes on installation in general. For more information on pnm2ppa, see INSTALL.REDHAT.txt or INSTALL.REDHAT.html, which (despite its name) has a lot of non-RedHat-specific information. Configuration ------------- Run 'configure' to setup the package. Run it with the following switches to get the same result as in the previous releases: ./configure --sysconfdir=/etc add: '--enable-debug' to get a more verbose program (default is no). This switch is intended for developers. '--disable-syslog' to disable the syslog feature. Its checked by default, if the system supports a syslog feature. This optione replaces the previous Makefile -D__NO_SYSLOG__ modification '--with-language=[EN | CZ | ES | FR | IT | NL]' to select one of the compiled in languages. 'EN' is the default. '--enable-vlink' to also build the 'parse_vlink' tool Compilation ----------- To build pnm2ppa, simply cd to the source directory, and type: make If you wish to do any further development of pnm2ppa, or study how it works so you can write a PPA backend to some other print system such as gimp-print, there is a useful tool called parse_vlink (and some documentation) that can be built in the ppa_protocol subdirectory. Installation ------------ Two binaries are created: calibrate_ppa and pnm2ppa (and on demand parse_vlink). calibrate_ppa is used to calibrate your printer (center the printed page, adjust the offset between black and color ink cartridges after changing them, etc.) See the CALIBRATION.* file for details. The other binary created, pnm2ppa, is a converter from a PNM image to a stream of PPA data that can be sent directly to the printer. The PNM image will be aasumed to have a resolution of 600 dpi (or 300dpi if the --dpi300 command line option is used). (Input at higher/lower resolutions will print with an incorrect larger/smaller size, if it is within the allowed page size limits.) These files can be generated with ghostscript. The binary-output pbmraw, pgmraw, ppmraw devices are supported (the text-output pbm, pgm, ppm devices are also supported, but the raw devices are MUCH faster!). The pnmraw and pgnmraw devices are switches that will try to select among the raw formats, as appropriate for the document, but do not always make the correct choice. You should now type make install to install the binaries (by default, in /usr/local/bin/) , the manpage (in /usr/local/man/man1), and the sample configuration file (/usr/local/etc/pnm2ppa.conf). You may change these locations by using the --sysconfdir/--prefix parameter when running the 'configure' step. *** IMPORTANT *** The default configuration file /usr/local/etc/pnm2ppa.conf sets the printer model to "version 0" (NULL printer). Unless you use the -v command line option to set the printer model (as is usually done by CUPS, lprNG, etc. scripts that call pnm2ppa), you must edit the configuration file to change this line and choose the correct printer version (720, 820, 1000, etc). If the printer version is unspecified, it defaults to "720" (valid for HP710C/712C/720C/722C). Other things you can do are documented in the sample configuration file /usr/local/etc/pnm2ppa.conf Usage ----- To print a postscript file with this program, You may use a simple shell script: #!/bin/sh cat $1 | \ gs -sDEVICE=ppmraw -sPAPERSIZE=letter -q -dNOPAUSE -r600 -sOutputFile=- - | \ pnm2ppa $2 $3 $4 $5 $6 $7 -i - -o - | lpr -l Any valid ghostscript papersize like "legal", "a4", etc. can be substituted for "letter" (in fact, "letter" is the default, so the "-sPAPERSIZE=letter" is not really needed.) If this script is placed in /usr/local/bin/ppaprint , ppaprint file.ps will print the postscript file file.ps in high quality color. Other options are: ppapprint file.ps --eco // economy color ink mode ppaprint file.ps --bw // black and white ppaprint file.ps --bw --eco // black and white economy mode etc. In the example, up to six pnm2ppa options can be added (see "man pnm2ppa" to list options, or "pnm2ppa --h" ). You may wish to replace the ghostscript output device "ppmraw" with "pbmraw" for only black and white printing - it is somewhat faster - or "pgmraw" for greyscale images. an ascii file could be printed in black and white with the script #!/bin/sh enscript -2rj $1 | \ gs -sDEVICE=pbmraw -sPAPERSIZE=letter -q -dNOPAUSE -r600 -sOutputFile=- - | \ pnm2ppa --bw $2 $3 $4 $5 $6 $7 -i - -o - | lpr -l Integration into Printing Systems ----------------------------------- (A) lpr, LPRng systems You can set up printer filters. See the documentation for your print spooler for information on how to do that. The subdirectory lpd of the pnm2ppa distribution contains a printer description file "printcap" and so filters to go with it. See the README.lpd file there. The subdirectory ppaSet of the pnm2ppa distribution contains a software to help configuring the printer (and better, for each user in the system), for both GTK and ncurses. Just see README file there. This software is fully compatible with the previous one, not a replacement. On some Linux distributions, (RedHat, Mandrake, ... etc.), packages that install pnm2ppa and appropriate printer filters will be available to do all this for you. On others, you must do this manually, for example using the files in our lpd subdirectory. See lpd/README.lpd in the pnm2ppa source distribution. Note: the "foomatic" data base at http://www.linuxprint.org now supports pnm2ppa, and produces scripts for configuring lpd-based systems. RedHat use this system since RedHat 7.2 An older printfilter system for lpd systems that also supports pnm2ppa is apsfilter (http://www.apsfilter.org). --------------- (B) PDQ ("Print, Don't Queue") PDQ is an alternative, spooler-free printing system available from http://pdq.sourceforge.net The pdq subdirectory of the pnm2ppa source provides a pdq driver, gs-pnm2ppa ---------------- (C) CUPS ("Common Unix Printing System") pnm2ppa is now integrated into the CUPS printing system: see http://www.cups.org. The "cupsomatic" scripts from the http://www.linuxprinting.org site support pnm2ppa on CUPS. "ppaSet": a Graphical User Interface for configuring pnm2ppa: ------------------------------- There is also a new graphical (gtk-based) utility for creating a pnm2ppa.conf configuration file and also can act as a front end to the calibration utility calibrate_ppa. It is written by Javier Sedano, and called ppaSet. Find it at http://sourceforge.net/projects/pnm2ppa. pnm2ppa-1.13/docs/en/INSTALL.BEOS0000644000076400007640000000307407201342011013050 00000000000000Note on installation on BeOS.

PPA Printer-Support RPM Packages for Red Hat Linux and Compatible Distributions

Information and installation instructions to accompany pnm2ppa packages for Red Hat Linux available at http://sourceforge.net/projects/pnm2ppa (Updated for pnm2ppa-1.10 and Red Hat 6.2 or later.) See the "Troubleshooting" section at the end of this document for fixes to some reported problems

Overview of HP's PPA DeskJet Printers.

Most of Hewlett-Packard's DeskJet(tm) printers use the PCL3 command language, and are currently supported by Ghostscript drivers. However, a few legacy models, namely

feature "Host-based" printing, and use HP's proprietary PPA (Printer Performance Architecture) protocol, instead of PCL. The two models in each series are physically identical; they just came with different bundled Windows software. All PPA printers are now discontinued from HP's product lines, but may still be found as second-hand legacy items.

PPA printers rely on software running on the host CPU to carry out the low-level processing of printer output that would be done by hardware in a standard PCL printer. The relation of PPA printers to PCL printers is analogous to the relation between "Winmodems" and true modems. Presumably, the idea at the time was that this would allow cheaper hardware to be used, but the decline in hardware prices probably meant that the savings were not significant, and PPA printing seems to have been abandoned.

Unfortunately, HP only supplied Windows software drivers for PPA printers, and have indicated that it is unlikely that they will ever make the proprietary PPA specs public. This is apparently because of concerns that publication of the specs might reveal crucial details of HP's trade secrets about "color science" to competitors. (A secondary issue is that it is apparently possible to physically damage the printer by sending it bad sequences of PPA commands, which is not the case for PCL commands, and it seems that HP do not wish to take any responsibility for such damage by encouraging unofficial PPA programming.)

In the past, Linux users often inadvertently purchased PPA DeskJet models, mistaking them for PCL3 DeskJets, which have traditionally been well-supported by Linux drivers. Fortunately, a reverse engineering effort, started in 1998 by Tim Norman, and continued by the pnm2ppa project at http://pnm2ppa.sourceforge.net, and http://sourceforge.net/projects/pnm2ppa has managed to produce drivers that provide basic printing functionality for these PPA printers under Linux and other Unices. While HP have recently begun to release their own Linux drivers for PCL3 DeskJets, they have not included drivers for their legacy PPA printers in this effort.

The pnm2ppa driver has been stable since v1.04, released October 2000, with no known reproducible bugs, except that image printing quality was not so good. This version has been distributed with Red Hat, and other Linux distributions. v1.10, released July 2002, contains a lot of changes that improve image quality, in particular by improved bidirectional printing, and always printing black on top of color.

A better improvement would be for someone to make a PPA backend to gimp-print, using pnm2ppa as a guide for how to send data to PPA printers. But, since PPA printers are now "legacy" hardware, and pnm2ppa appears to work fine for most printing tasks, it is unlikely that any new developers will be interested in doing this, and there is currently no further development anticipated. The project is currently in "low-maintenance mode".

The pnm2ppa driver for color printing with PPA printers.

Color printing with PPA printers is supported by the pnm2ppa driver which is the successor to the older black-and-white-only driver pbm2ppa-0.8.6 developed by Tim Norman.

pnm2ppa translates portable anymap (pnm) format images into a stream of PPA instructions which can be sent to the printer. In the driver name, "pnm" stands for the superset of three image formats: ppm (portable "pixmap" format for color images), pgm (portable "greymap" format for greyscale images), and pbm (portable "bitmap" format for black and white images).

Ghostscript has a number of "output devices" that produce pnm format output from postscript or pdf input. These come in plain (text) and raw (binary) variants. While pnm2ppa can now interpret both plain and raw pnm formats, there is no point in using the inefficient plain formats: always use the "raw" output devices, which are:

The last two output devices are switches that try to analyze the image, and select an appropriate format; however, they are not recommended for routine use, as they may inconsistently choose the format. The ghostscript packages supplied with all recent Red Hat distributions provides all these devices. To see the list of available ghostscript output devices, type the command line 
gs --help
if the required ppmraw or pbmraw devices are not shown, you will have to upgrade your version of ghostscript.

The data must be streamed directly from ghostscript to pnm2ppa to the (local) printer without being stored in any intermediate file: one ppm-format (color) US Letter size page is represented by 3x5100x6600 Bytes (100MB) in binary format and four times this amount in text format.

An example of a command line for printing a postscript file file.ps using gs (ghostscript) and pnm2ppa is 

cat file.ps | gs -q -sDEVICE=ppmraw -r600 -sPAPERSIZE=letter -dNOPAUSE \
 -sOutputFile=- - | pnm2ppa --eco -v 720  -i - -o - | lpr -l
(all on a single line). In this example the paper size is explicitly given to gs as US Letter (8.5"x11") size (letter); pnm2ppa no longer needs to be told what the paper size is, and will read it from the gs output (and check that it is a permitted size for the printer type). The pnm2ppa option --eco specifies "EconoFast" mode, for a lower quality output which uses less ink, and prints faster, and -v 720 specifies the PPA printer as belonging to the DeskJet 720C series.

Obviously, it would be impractical to type such a command each time one wished to print something, and since RedHat 6.2, printfilter support for pnm2ppa is built into Red Hat's printer configuration scheme, so after configuration, the simple command 

lpr file.ps
should successfully print a postscript file. However, in case you wish to check if something is misconfigured in the print filters, you can use a script like the above one to bypass them and check that the printer is working.

Available RPM packages. A RPM package for pnm2ppa is part of the Red Hat Linux distribution starting with Red Hat 6.2. You will also find a RPM package for the latest release of pnm2ppa at http://sourceforge.net/projects/pnm2ppa.

The latest version at the time of writing is pnm2ppa-1.10-1rh7x.i386.rpm, and is built on Red Hat 7.3, or pnm2ppa-1.10-1rh62.i386.rpm, built on Red Hat 6.2. If you are running a different release of Red Hat (or a different Linux distribution) you may need to download and rebuild the source RPM pnm2ppa-1.10-1.src.rpm instead: 

rpm --rebuild pnm2ppa-1.10-1.src.rpm
(You must be root to do this, and have the necessary compilers installed; on Red Hat, the rebuilt binary RPM will be created in the directory /usr/src/redhat/RPMS/i386/.)

Red Hat 6.2 and later also includes support for configuring your printer to use pnm2ppa. (Information necessary for configuring pnm2ppa on older Red Hat releases has been removed from this document; for this, see the documentation that came with pnm2ppa-1.04, or update your RedHat distribution.) Note: If you are still using Red Hat 6.2, you may wish to update the print filter support for pnm2ppa that comes with it. The pnm2ppa-1.10-1rh62* RPM package supplies the necessary files that you can use. After installing this RPM, see /usr/lib/rhs/rhs-printfilters/README.ppa for details.

Installing the pnm2ppa RPM package and setting up the PPA printer.

To install the RPM package, you must log in as the system administrator, root.

Now begin the installation. First install the pnm2ppa RPM: 

rpm -Uvh pnm2ppa-1.10-1*.i386.rpm
The pnm2ppa executable gets installed in /usr/bin/.

The Linux kernel will be able to autodetect IEEE-1284 devices like PPA printers, provided they are attached to the parallel port with a bidirectional IEEE-1284 cable. (If your printer works under Windows, you have the correct cable.) A script detect_ppa is provided by the pnm2ppa RPM: just type 

detect_ppa
to confirm that your Printer is found. A typical message from the printer, which will be displayed if autodetection is successful, is: 
CLASS:PRINTER;
MODEL:DESKJET 820C;
MANUFACTURER:HEWLETT-PACKARD;
DESCRIPTION:Hewlett-Packard DeskJet 820C;
COMMAND SET:SCP,VLINK;
A list of PPA printers found, and the parallel ports to which they are attached, will also be shown.

At this point it is useful to test that your printer is working, by printing a test page using the supplied script test_ppa which the RPM has installed. You will need to know your printer model (710, 712, 720, 722, 820, 1000), your paper size (letter, legal, a4) and the printer port the printer is attached to. If it is attached to the primary parallel port, this is (usually) /dev/lp0. Type 

test_ppa
and give the details about printer model. papersize, and port number when prompted. You will then be asked whether to print a test page, an offset calibration page, or an alignment calibration page, etc.

Configuring the print filters.

Note: Red Hat 7.3 now features either CUPS or LPRng printer management. The configuration tools should be able to configure pnm2ppa, using the information about it taken from the Linux Printer Database. Apart from the addition of a new --dpi300 option to accept 300dpi input (useful for printing PNM output from 300dpi scanners), there have been no changes in the pnm2ppa command line since the pnm2ppa-1.0 release, so the configuration scripts are stable. (They can only use the default 600dpi input mode.)

Since Red Hat 7.1, there is a graphical printer configuration utility printconf-gui. In Red Hat 6.2 and 7.0, the older configuration utility called printtool is used. In either case, start the "Red Hat Linux Print System Manager" (as root) to configure the printer, either by clicking on the printer icon in Red Hat's "control-panel", or just typing 

printtool
which also starts printconf-gui in the newer Red Hat releases.

Configuring the print filters with the Red Hat 6.2/7.0 printtool

(Skip this section unless you are still using Red Hat 6.2 or 7.0)

The following description is for the older printtool that is used by Red Hat 6.2/7.0. The printer configuration utility printconf-gui for Red Hat 7.1 and later is a little different, as it is based on the foomatic printer configuration database which contains entries for pnm2ppa (but not the older pbm2ppa). You should be able to easily figure out what to do: it can configure all pnm2ppa command-line options in the Driver Options screen.

In the Red Hat 6.2/7.0 Print System Manager window, click on Add, then in the "Add a Printer Entry", select Local Printer, and click Ok. Hopefully, the port on which the printer is attached will be listed as "Detected" (if not, fix the problem before continuing, perhaps by adding the line "alias parport_lowlevel parport_pc" to /etc/conf.modules). You will now have to "edit the local printer entry" for the PPA printer. Click on Select to chose the "Input filter". The Configure Filter screen will open. Among the many printer entries in the list "Printer Type", you should find three entries

Select the appropriate entry for your printer model. You will then be presented with various options: When you have made your choices, click on Ok to save your selections and close the "Configure Filter" screen, and then click on OK to close the "Edit Local Printer Entry" screen.

You are now back in the "Red Hat Print System Manager" screen; highlight the printer you just configured, and, in the Tests menu, choose Print Postscript test page to print a test page using the Red Hat print filters. If this printed correctly, your print system is set up to use the PPA printer, just like any of the other printers that the Red Hat print filters support.

Configuring pnm2ppa.conf and calibrating the printer.

A number of printer parameters are set to reasonable default values for each of the printer models, but you may wish to "fine tune" or calibrate your printer. The default values can be overridden by entries in the configuration files, which by default are /etc/pnm2ppa.conf and /etc/pbm2ppa.conf. At 600dpi, one pixel is 1/600 inch.

The user-adjustable parameters are:

Use test_ppa to print various test pages or calibration patterns to adjust the offsets.

If you wish to specify these parameters using the command-line options described above, in Red Hat 6.2/7.0 some of them can be entered in the "extra GS options" box using the Print System Manager (printtool), as described above. In Red Hat 7.1 and later, all command-line options can be set using the new printconf-gui utility.

Utility programs for the printer.

HP's Windows software provides a utility program that sends PPA commands to tell the printer to perform tasks like cleaning the printheads, etc.

On Red Hat Linux, You can use test_ppa (which acts as a command-line front-end for calibrate_ppa) to print head-cleaning patterns.

There is a graphical (gtk-based) tool written by Javier Sedano for creating a pnm2ppa.conf file and acting as a front end to calibrate_ppa. This is called ppaSet, and a beta version of it can be found in the same place as the pnm2ppa-1.10 distribution at http://sourceforge.net/projects/pnm2ppa

There was also at one time a proposal to add support for PPA printers to the PUP (Printer Utility Program) utility, which is also a project at http://www.sourceforge.net. However, as of the time of writing, no PUP support for PPA printers is available.

Troubleshooting

The first thing to do is to look at the messages from pnm2ppa in the system log to see what is happening, whether pnm2ppa actually received any input, and if it was valid. (You may need to enable system log messages in /etc/pnm2ppa.conf, see above.) Maybe ghostscript failed to convert your postscript file into PNM format: in that case the system log reports "Fatal Error! Input image (pnm2ppa) is not a PNM image". (note: when this occured, older versions of pnm2ppa reported "Input image is not a supported PNM format" which may have been confusing). This is because the input received by pnm2ppa was not a valid PNM image, but instead ghostscript failed to produce any PNM output at all, and its only output was probably just an error message. This is not a pnm2ppa problem!

Here are suggestions for dealing with other problems that you may encounter.

Contacting the pnm2ppa project.

Send comments or corrections (about this document or the RPMS) to: ppa-rpms@users.sourceforge.net

There are three mailing lists, pnm2ppa-announce@lists.sourceforge.net (announcements), pnm2ppa-users@lists.sourceforge.net (users helping users) and pnm2ppa-devel@lists.sourceforge.net (developers). You can subscribe to them, or browse their archives, at http://sourceforge.net/projects/pnm2ppa. (The older pnm2ppa mailing lists died with the ListBot service)

To contact the developers, subscribe to ppa.devel and post a message.

There are Public Forums for posting questions and comments at http://sourceforge.net/projects/pnm2ppa (but whether you get any help from these, depends on whether anyone is reading them (unlikely!)).

This corresponds to the gs -r600 ... or gs -r300 ... ghostscript options. If other higher/lower input resolutions are used, the size of the printed image will be larger/smaller, provided it is within the printer's allowed size range.

In either case, start the "Red Hat Linux Print System Manager" (as root) to configure the printer, either by clicking on the printer icon in Red Hat's "control-panel", or just typing printtool which also starts printconf-gui in the newer Red Hat releases. Configuring the print filters with the Red Hat 6.2/7.0 printtool (Skip this section unless you are still using Red Hat 6.2 or 7.0) The following description is for the older printtool that is used by Red Hat 6.2/7.0. The printer configuration utility printconf-gui for Red Hat 7.1 and later is a little different, as it is based on the foomatic printer configuration database which contains entries for pnm2ppa (but not the older pbm2ppa). You should be able to easily figure out what to do: it can configure all pnm2ppa command-line options in the Driver Options screen. In the Red Hat 6.2/7.0 Print System Manager window, click on Add, then in the "Add a Printer Entry", select Local Printer, and click Ok. Hopefully, the port on which the printer is attached will be listed as "Detected" (if not, fix the problem before continuing, perhaps by adding the line "alias parport_lowlevel parport_pc" to /etc/conf.modules). You will now have to "edit the local printer entry" for the PPA printer. Click on Select to chose the "Input filter". The Configure Filter screen will open. Among the many printer entries in the list "Printer Type", you should find three entries o HP DeskJet 1000 series (PPA) (for 1000Cse, 1000Cxi models) o HP DeskJet 710/720 series (PPA) (for 710C, 712C, 720C, 722C models) o HP DeskJet 820 series (PPA) (for 820Cse, 820Cxi models) Select the appropriate entry for your printer model. You will then be presented with various options: o The Driver Description box contains information about the driver (you may have to use the scrollbar at the right of the box to read it all). o The resolution box shows a single resolution (600x600). There are no other choices. o The Paper Size box allows various choices (only letter, legal, and a4 seem correspond to native paper sizes printed by the Red Hat print filters; the other choices, (a3, ledger, ...) appear to get resized by the print filters to print on US Letter size paper (?) ). (Other paper sizes cannot be selected this way, but you can print to any papersize, if it supported by both ghostscript and the printer, using a script, as described above, that bypasses the RedHat printfilters.) o The Color Depth/ Uniprint Mode box allows various selections of color and print quality (These are achieved by using various combinations of the pnm2ppa options --eco (EconoFast mode), -p (disable black ink cartridge) and --bw (black and white printing only), without direct intervention by the user.) The choices (in the most recent printerdb database) are: o Black and White, econofast mode (--bw --eco) o Black and White, normal quality (--bw) o Color, econofast mode (--eco --fd) o Color, normal quality (--eco) o Color, high quality o Color, normal quality, black ink disabled (-p --eco) o Color, high quality, black ink disabled (-p --uni) (These are the choices that will be presented by "official" rhs- printfilters-1.72; if you installed a pnm2ppa RPM package from the SourceForge pnm2ppa site, you may have a file /usr/lib/rhs/rhs- printfilters/README.ppa explaining how to modify earlier versions of rhs-printfilters to show these updated choices.) You may also see a choice to use the older "Legacy" driver pbm2ppa (black and white only); this is is stable but unmaintained; it may still be a useful alternative to pnm2ppa on older, slower systems with less available memory. o The three Printing options are not relevant here, and should not be selected. They are for direct printing of text (ascii) to non- postscript printers, but since the only way of printing text files with pnm2ppa is by first converting them to postscript(tm), this is not possible on the PPA printer. o It is important that the choice "Fast text printing (non-PS printers only)" is NOT selected, so that the print filters will convert text files to postscript before printing. o The Margins entries control the margins used when printing text files (these are instructions to the text-to-postscript conversion process). o The Extra GS options box is not only a place for adding options for ghostscript, but also for the PPA drivers. Leave this box empty unless you know what you are doing. As explained in the text in the Driver Description box (you did read it, didn't you ?), the entry should be in the format: gs_options PPA ppa_options Anything before the "PPA" is interpreted as a gs option, anything after it is interpreted as a ppa option. You can learn about pnm2ppa options by typing either "man pnm2ppa" or "pnm2ppa --help" at a com- mand line (hopefully, these two sources of information will be consis- tent with each other!); When you have made your choices, click on Ok to save your selections and close the "Configure Filter" screen, and then click on OK to close the "Edit Local Printer Entry" screen. You are now back in the "Red Hat Print System Manager" screen; highlight the printer you just configured, and, in the Tests menu, choose Print Postscript test page to print a test page using the Red Hat print filters. If this printed correctly, your print system is set up to use the PPA printer, just like any of the other printers that the Red Hat print filters support. Configuring pnm2ppa.conf and calibrating the printer. A number of printer parameters are set to reasonable default values for each of the printer models, but you may wish to "fine tune" or calibrate your printer. The default values can be overridden by entries in the configuration files, which by default are /etc/pnm2ppa.conf and /etc/pbm2ppa.conf. At 600dpi, one pixel is 1/600 inch. The user-adjustable parameters are: o verbose 1 and silent 1. These control messages about progress and errors from pnm2ppa. By default, messages are sent to the system log /var/log/messages. The verbose 1 keyword send copies to stderr, the standard error stream to the terminal. The silent 1 keyword silences the stream of messages to the system log. o The system log messages may be silenced in the default configuration file; switch off "silent" mode with "silent 0" for debugging printer problems (or use verbose mode). o The version keyword can be used to specify the printer model as 710, 712, 720, 722, 820, or 1000. It is not needed if you use the RedHat printool to configure the printer. o xoffset and yoffset: the x-offset and y-offset (in pixels) of the printed image on the page, which should be chosen so the image is correctly centered on the paper. (These can also be set with the -x and -y options.) See CALIBRATION.html (or CALIBRATION.txt) for more information. o topmargin, bottommargin, leftmargin, rightmargin: the four margins, which define the distances (in pixels) from the edges of the paper to the printed region; parts of the image that are outside these margins will not be printed. (These can also be set with the -t , -b , -l , and -r options.) o ColOffsX and ColOffsY: the x-offset and y-offset (in pixels) between the color image produced by the color ink printer head, and that produced by the black ink printer head. These should be recalibrated each time an ink cartridge is replaced. See CALIBRATION.html (or CALIBRATION.txt) for more information. o blackshear and colorshear: these are x offsets between right-to- left and left-to-right sweeps of the print head, one for the black printing and one for the color printing. These provide sideways offsets (in pixels) of the right-to-left sweeps, that can be used to correct "shearing" when printing in modes that use bidirectional print head sweeps. o unimode 1 will make unidirectional print sweeps (left-to-right) the default, instead of bidirectional sweeps. The --uni and --bi options can control how a particular print run is printed. Unidirectional printing is only useful (it is slower) if there are issues of "shearing" in high quality image printing. o blackness : this takes values 0,1,2,3 or 4 drops of black ink per pixel, and controls black ink density in black-and-white and "text- like" black regions in color printing. At present, this has no effect on printing with the black ink cartridge disabled, or on black regions identified as "image-like". (This can also be set with the -B option, where n is the number of drops.) o GammaR, GammaG, and GammaB: the are the three "gamma" parameters that define the standard color correction curves for red, green, and blue. Changing these will affect how colors appear (decreasing any Gamma enhaces the corresponding color). The Gamma values are specified as decimal numbers, with Gamma = 1.0 corresponding to no color correction. o Gamma values can also be specified using integer numbers RedGammaIdx, GreenGammaIdx, BlueGammaIdx; These are determined by a procedure discussed in COLOR.html or COLOR.txt, which involves printing a test page. The papersize keyword specifies the paper size used for this testpage, because it is produced by pnm2ppa without the input that usually specifies the page size. o The keywords black_ink 0, color_ink 0, cyan_ink 0, magenta_ink 0, and yellow_ink 0 can be used to switch of the various inks; this can be useful in troubleshooting and debugging pnm2ppa. Use test_ppa to print various test pages or calibration patterns to adjust the offsets. If you wish to specify these parameters using the command-line options described above, in Red Hat 6.2/7.0 some of them can be entered in the "extra GS options" box using the Print System Manager (printtool), as described above. In Red Hat 7.1 and later, all command-line options can be set using the new printconf-gui utility. Utility programs for the printer. HP's Windows software provides a utility program that sends PPA commands to tell the printer to perform tasks like cleaning the printheads, etc. On Red Hat Linux, You can use test_ppa (which acts as a command-line front-end for calibrate_ppa) to print head-cleaning patterns. There is a graphical (gtk-based) tool written by Javier Sedano for creating a pnm2ppa.conf file and acting as a front end to calibrate_ppa. This is called ppaSet, and a beta version of it can be found in the same place as the pnm2ppa-1.10 distribution at http://sourceforge.net/projects/pnm2ppa There was also at one time a proposal to add support for PPA printers to the PUP (Printer Utility Program) utility, which is also a project at http://www.sourceforge.net. However, as of the time of writing, no PUP support for PPA printers is available. Troubleshooting The first thing to do is to look at the messages from pnm2ppa in the system log to see what is happening, whether pnm2ppa actually received any input, and if it was valid. (You may need to enable system log messages in /etc/pnm2ppa.conf, see above.) Maybe ghostscript failed to convert your postscript file into PNM format: in that case the system log reports "Fatal Error! Input image (pnm2ppa) is not a PNM image". (note: when this occured, older versions of pnm2ppa reported "Input image is not a supported PNM format" which may have been confusing). This is because the input received by pnm2ppa was not a valid PNM image, but instead ghostscript failed to produce any PNM output at all, and its only output was probably just an error message. This is not a pnm2ppa problem! Here are suggestions for dealing with other problems that you may encounter. o Printing fails in the middle of a print run, perhaps when a figure embedded in the document is printing (in the latest pnm2ppa versions, printing finishes normally, but an incomplete document is printed). The system log reports that read_line could not read the image, and found EOF (end-of-file). This probably means that ghostscript's "ppmraw" or "pgmraw" output device started correctly, but failed for some reason before finishing the image conversion from postscript to PNM format, usually leaving a core dump. (This has been seen to happen in ghostscript 5.10 ; upgrading to ghostscript 5.50 solved the problem.) If you cannot upgrade, try printing the document in black-and-white using the ghostscript "pbmraw" output device. o You printed an image file using a "high quality" printer setting, but it has visible horizontal lines on it and printing under Windows(tm) 9x doesn't show this effect (except in "economode"). These are probably "swath boundaries", showing the junction between different sweeps of the print head. Solution: using unidirectional printing (PPA option --uni, or unimode 1 in /etc/pnm2ppa.conf) helps a little. this problem is fixed in the pnm2ppa-1.10 release o "Flashing light syndrome ". Your printer usually works, but you have found that some particular documents cause the printer to fail, and the lights on its panel start flashing rapidly in sequence. Solution, turn the printer off and back on again. This is not supposed to happen any more; if it happens reproducibly, contact the pnm2ppa developers, and offer to make the offending file available for testing and diagnosis of this problem. (Don't sent it to the Mailing List unless requested). Bug reports can be filed at the SourceForge pnm2ppa site. o You wish to print on envelopes or other non-standard media not supported by the print filters? Solution: if you can get Ghostscript (gs) to produce the correct image, and the paper size is in the range allowed by your printer, you should be able to do this with a script that bypasses the print filters, as described earlier in this document. o Colors look wrong, or do not match what the Windows(tm) 9x driver produces. Solution: check that your color ink cartridge is not running out of some ink color; if not, (a) adjust the "gamma" entries in /etc/pnm2ppa,conf, or (b) install a customized color calibration file /etc/pnm2ppa.gamma. See the file COLOR.html (or COLOR.txt) for more information. Contacting the pnm2ppa project. Send comments or corrections (about this document or the RPMS) to: ppa-rpms@users.sourceforge.net There are three mailing lists, pnm2ppa-announce@lists.sourceforge.net (announcements), pnm2ppa-users@lists.sourceforge.net (users helping users) and pnm2ppa-devel@lists.sourceforge.net (developers). You can subscribe to them, or browse their archives, at http://sourceforge.net/projects/pnm2ppa. (The older pnm2ppa mailing lists died with the ListBot service) To contact the developers, subscribe to ppa.devel and post a message. There are Public Forums for posting questions and comments at http://sourceforge.net/projects/pnm2ppa (but whether you get any help from these, depends on whether anyone is reading them (unlikely!)). pnm2ppa-1.13/docs/en/INSTALL.SOLARIS0000644000076400007640000000173407343336252013456 00000000000000On Solaris systems, you will probably have to install the GNU "libiberty" library (-liberty) which provides getopt_long for Solaris; get it at http://sunfreeware.com (look for the package "libiberty.so" in the list of freeware) and install it into /usr/local/lib. The tarball of the package is called "shared-libiberty.tar.gz". If you use the precompiled library libiberty-i386.so that it supplies for x86 systems, rename it to libiberty.so when you install it. Otherwise, build the library from source. Uncomment the Makefile line adding an entry for -liberty to LDFLAGS. You may also need to compile with the -D__NO_SYSLOG__ option to suppress system log messages. See the Makefile. If "make install" fails, manually copy the pnm2ppa and calibrate_ppa binaries, the manpage pnp2ppa.1, and the configuration file pnm2ppa.conf to their appropriate locations. The "install" command on Solaris does not have the -b (backup) option. uncomment the Makefile line entry for this.pnm2ppa-1.13/docs/en/INSTALL.SUSE0000644000076400007640000000246007176353610013117 00000000000000Installation of pnm2ppa with S.u.S.E. Linux ------------------------------------------------------ 1. Installation of program package pnm2ppa Follow the standard installation instructions in INSTALL and CALIBRATION. The driver pnm2ppa is installed to /usr/local/bin. The manual page pnm2ppa.1 is installed in /usr/local/man/man1. 2. To integrate pnm2ppa into the BSD print spooler of the Linux system we create printer spoolers in /etc/printcap, to print postscript files in color or black and white, and to print plain ascii files. See the file README.lpd in the subdirectory "lpd" of the pnm2ppa distribution. This shows how to set up five printer descriptions: coloreco (normal quality color,the default); color (high quality color) bweco (economy mode black) bw (high quality black and white) ascii (for printing text files using enscript) (Maybe there is a better way, using SUSE's own printing configuration system; if so please let us know). 3. Now you are ready to print files with # lpr filename.ps which is equivalent to: #lpr -P coloreco filename.ps or explicitly specify the color and quality mode: #lpr -P bweco filename.ps #lpr -P bw filename.ps #lpr -P coloreco filename.ps #lpr -P color filename.ps and for ascii (text) files: # lpr -P ascii filename pnm2ppa-1.13/docs/en/LICENSE0000755000076400007640000004400007132471700012305 00000000000000 GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.

1. Networking HP DeskJet PPA printers with SAMBA

1.1 Overview of PPA printers.

The HP DeskJet 710/712C, 720/722C, 820Cse/820Cxi and 1000Cse/1000Cxi printers are "Winprinters" which are designed only for use with MS Windows operating systems. HP supplies Windows-only software that processes the input data into the proprietary and unpublished PPA ("Printer Performance Architecture") protocol.

HP states that these printers are not supported as networked printers, but they in fact function correctly as shared (SMB) printers under MS Windows.

In this document, the Host is the computer to which the PPA printer is physically connected, and the Clients are other computers on the network that wish to print documents on the PPA printer.

In the Windows printing system, separate copies of the HP PPA printer drivers are installed on each Client, and are run on the Client to produce PPA output that is sent over the network to be spooled on the Host to which the printer is attached.

HP's drivers are only supplied for Windows systems. The independently-produced pnm2ppa driver runs on Linux, some other Unix systems, and BeOS.

This document describes various tested strategies for using pnm2ppa and the samba suite of SMB tools to allow the PPA printer to be attached to a non-Windows host on a (TCP-based) SMB network, or to allow non-Windows Clients to receive printing services from a Host on the network.

1.2 Choice of protocol for sending over the network.

There are two possible ways to send printer data from a Client to the printer Host over the network.

  • as PPA data, created by a driver on the Client. This is what happens when using conventional printer sharing on Windows.
  • as PostScript data, created on the Client, which is then translated into PPA instructions by drivers running on the printer Host.
Since PPA data is rather large, the first method involves sending larger amounts of data over the network, which may be why HP do not officially support PPA DeskJets as networked printers. It also requires that PPA drivers are installed on the Client.

The Host to which the printer is attached can thus provide two classes of printing services:

  • PPA printing services: the Host accepts PPA-format printing jobs created on the Clients either with HP's native PPA drivers (Windows Clients) or pnm2ppa (Unix/Linux/BeOS Clients);
  • PostScript printing services: the Host accepts PostScript-format printing jobs created on any postscript-capable Client, and converts them to PPA format using either HP's native PPA drivers (Windows Host) or pnm2ppa (Unix/Linux/BeOS Host);
It is useful to set up the Host to offer both types of service, sharing a common spooling system.

2. Configuring the Printer Host.

2.1 Configuring a Linux/Unix Host to share a PPA printer using Samba.

It is assumed that pnm2ppa is installed and working to provide local printing services on the Host, and that lpr will invoke a full set of print filters, as (e.g.) in Red Hat 6.2. The PPA printer is installed with the printer name lp, and samba is assumed to be installed. General Samba configuration issues involving security levels, network password, etc, are outside the scope of this document (see the SMB-HOWTO). You must log in as root to configure Samba.

Here is a sample entry setting up two public printer shares in the Host's /etc/smb.conf file. The printer HP722C-PPA is for printing by a Client that sends PPA output from pnm2ppa or the HP drivers across the network, and HP722-PS is for Clients that produce PostScript output: 

[HP722C-PPA]
    comment = HP 722C printer on Linux (PPA input)
    path = /var/tmp
    printer name = lp
    writable = yes
    public = yes
    printable = yes
    print command = lpr -l -r -h -P %p %s
[HP722C-PS]
    comment = HP 722C printer on Linux (Postscript input)
    path = /var/tmp
    printer name = lp
    writable = yes
    public = yes
    printable = yes
    print command = lpr -r -h -P %p %s
The only differences besides the names are that the print command for HP722-PPA uses the " -l " "pass-through" option so print filters are not applied. The path entry uses /var/tmp because this is (presumably) a world-readable and -writable area for temporary files.

After editing /etc/smb.conf to include these entries, save it, and test its syntax with Samba's testparm utility. Then restart samba (run "/etc/rc.d/init.d/smb restart" on Red Hat).

2.2 Configuring a Windows Host to share a PPA printer with non-Windows Clients.

The Host is assumed to be a Window 98 system, and the PPA printer is assumed to be a HP722C installed with the native HP PPA drivers supplied on HP's installation CD. Some details may vary on other Windows versions.

First set up a shared printer that can accept PPA input from both networked Windows Clients, and from networked non-Windows Clients that use pnm2ppa.

  • IMPORTANT!: A PPA printer attached to a Windows Host shared with a Client running pnm2ppa has the following limitation:
    • Bi-Directional communication between the Windows Host and the printer must be disabled.
    If it is not done, a General Protection Fault will usually occur on the Windows Host when pnm2ppa sends output to the shared printer. (A "Hpfbkg06" error occurs, and the printer becomes nonfunctional until the Windows system is rebooted.) Disabling bi-directional communication appears to be a minor inconvenience: according to HP, the print quality is unaffected, but the "advanced features of the Status Monitor" will no longer send reminders to align the print cartridges after a new cartridge is installed, or send error messages associated with the ink cartridges or the banner lever.

You may be able to avoid disabling bi-directional communication by using an emulated Postscript printer to serve non-Windows Clients without using pnm2ppa (see below).

To turn off bi-directional communication between the Windows Host and the printer, open the Settings/Printers folder, then right-click on the printer icon, and open the Properties dialog. Select the Details tab, and click on Spool Settings, then choose the setting "Disable bi-directional support for this printer". If you have any difficulties, try rebooting Windows after the change, or see HP's support document http://www.hp.com/cposupport/printers/support_doc/bpd06455.html about disabling bi-directional communication.

To set up the Host to share the printer, right-click on its icon in the Settings/Printers folder, and select Sharing, then assign it a Share Name like HP722C-PPA , and enter a Comment Line like "HP 722C printer on Windows 98 (PPA input)".

You may now also wish to set up an emulated Postscript printer that accepts Postscript input from the Client, and prints it using HP's PPA drivers running on the Host, instead of on the Client. See the section Emulating a PostScript printer on a Windows Host

If you have installed and successfully tested the emulated printer, set it up for sharing on the network. Right-click on its icon in the Settings/Printers folder, and select Sharing, then assign it a Share Name like HP722C-PS, and enter a Comment Line like "HP 722C printer on Windows 98 (PostScript input)".

The emulated printer will appear like a Postscript printer to the Clients. If it provides acceptable printing services to the non-Windows clients, you will not need to connect pnm2ppa printers to HP722C-PPA, and will be able to re-enable bi-directional communication between the HP drivers and the printer. (However, the extra processing involved in the emulation may be unacceptably slow, or turn out to use too much of the host's CPU)

3. Configuring the Printing Clients.

3.1 Setting up Printing from a Windows Client.

Open the Settings/Printers folder, and start the Add Printer Wizard. Choose to add a Network Printer, and browse the network to find the Printer Shares you configured on the host (e.g., HP722C-PPA and HP722C-PS). If they are not visible, either the Host or the network is not properly configured. Correct the problem before proceding.

Normally, you will probably want to use the native Windows HP PPA drivers, so select the printer Share that accepts PPA input (e.g., HP722C-PPA). If the Host is a Windows Host, it will provide the drivers over the network, otherwise you will have to find the printer in the list of available HP Printer drivers, or click on Have Disk and install them from HP's installation CD. You then get a chance to change the name with which the printer will be known on the Client. Finally, you should choose to print a test page.

You might instead (or also) want to set up printing services using the Printer Share that accepts Postscript (e.g., HP722C-PS). In that case, if the Host is not a Windows Host, choose a "generic" PostScript printer like the Apple LaserWriter II NT or the Digital turboPrintServer 20/Net.

If the test page prints sucessfully, you are finished!

3.2 Setting up Printing from a Linux/Unix Samba Client

First examine the network by opening a terminal window and using the command 

smbclient -L hostname
(where "hostname" should be replaced by the network name of the Host to which the printer is attached). This will list the SMB services provided by that Host. (Alternatively, your system may have some graphical front-end to smbclient that allows you to inspect the network.) The list should include the Printer Share(s) you configured on the Host (e.g., HP722C-PPA and HP722C-PS). If these are absent, you must first identify and correct the problem.

You must now configure the printer. The details of how to do this will vary between Linux/Unix distributions, but there will probably be support for network printing using Samba.

If the Printer Share you wish to use is intended to accept PPA input (e.g., HP722C-PPA), configure the Client to use the pnm2ppa driver.

If it is intended to accept PostScript input (e.g., HP722C-PS), configure the Client to print to a PostScript printer.

You may wish to configure both types of printers, and experiment to see which provides the best printing services on your network.

See the SMB-HOWTO documentation for more information.

4. Emulating a PostScript printer on a Windows Host.

If you do not have commercial PostScript emulation software for Windows that will work with your HP PPA DeskJet (the author is unaware of any such software that supports PPA printers), you can use Ghostscript together with HP's native Windows drivers.

4.1 Installing Ghostscript as the emulation software.

From the Ghostscript home page http://www.cs.wisc.edu/~ghost/ download and install (in this order) the Windows packages of

  • Ghostscript (PostScript Emulation Software).
  • GSview (Ghostscript previewer, provides gsprint).
  • RedMon (printer port redirection utility).
(Install these using their setup.exe installation tools, and do not manually set up any configuration files for gsprint or RedMon.) You must now follow the detailed instructions below, and use the Windows "Add Printer Wizard" to add a postscript printer, and then configure it to use the gsprint utility that comes with GSview, and redirect the output to your HP PPA DeskJet using the RedMon utility.

4.2 Adding the fictitious Postscript printer.

In the following, I assume your printer is a HP DeskJet 722C, and is installed with its native Windows Drivers as a printer called "HP DeskJet 720C Series". Change printer name entries below as appropriate for your printer model.

The following instructions are tested on Windows 98, and may differ on other Windows variants.

Open the Settings/Printers folder.

First check that the HP PPA Deskjet is correctly installed, using HP's native Windows drivers. Right-click on its icon, and select its Properties dialog. The General Properties screen will open. This shows the exact name that the printer was given when it was installed. Make a note of it, and use the Print Test Page button to confirm that the printer is working. (The "Printer name:" line on the test page will also show the exact name of the HP PPA Deskjet that you will need to use when configuring the emulated postscript printer below). When you are done, click on OK to close the dialog.

Now start the Add Printer "Wizard". Make the choices:

  • install a local printer
  • select a PostScript printer from the list of printers; (e.g., one of the Apple LaserWriter models: the Laserwriter II NT is known to work; Digital PrintServer models such as the turboPrintServer 20/Net have also been recommended). This will provide a suitable postscript driver.
  • From the list of Available Ports, choose "FILE: Creates a file on disk" (you will change this after the printer is installed)
  • set as default printer?: NO
  • Print test page?: NO

4.3 Redirecting the output to the PPA printer.

After the printer has been installed, right-click on its icon, and rename it to something like, e.g., "Ghostscript+HP722C". Then right click again and open its Properties dialog.

On the General tab screen, enter something informative in the Comment box, such as " Emulated Postscript printer; output redirected to a HP722C DeskJet printer" (optional).

Next select the Details tab. The box "Print using the following driver:" should show the Postscript driver you selected (e.g., Apple LaserWriter II NT).

  • Click on Add Port. Select other, then Redirected Port, which should be available if RedMon was correctly installed, and click on OK to accept these settings and close the Add Port dialog. On the Details tab screen, The box "Print to the following port:" should now show a redirected port such as "RPT1 [Redirected Port]".
  • Click on Port Settings.
    • In the box "Redirect port to the program:", enter the path to the gsprint program. (If you accepted the defaults when installing it, this may be C:\Ghostgum\gsview\gsprint.exe; you may search for it by clicking on Browse).
    • In the box "arguments for this program are:" enter the arguments to be passed to the gsprint program (there is a document gsprint.htm with more details of these in the folder containing gsprint.exe). Suggested arguments are: 
       -printer "HP DeskJet 720C Series" -color -
      Replace "HP DeskJet 720C Series" by the (quoted) exact name of the HP PPA DeskJet printer that you made a note of earlier. (If you do not copy this name exactly, including any capitalization or spaces, things may not work!) The -color argument is needed to enable color printing; (Whether you actually get color printing will depend on the local settings of the "HP DeskJet 720C Series" printer that really prints the document.) The final " - " is required: without it, the output of gsprint will not get redirected to the printer.
    • The box "Output" should show "Program handles output".
    • In the box "Run", select "hidden".
    • The box "Shutdown delay" will say "300 seconds". Print jobs for which processing by gsprint takes longer than this will be terminated, to avoid blocking the printer spool queue. Increase this limit if necessary.
    Now click on OK to close the Port Settings dialog.
  • Click on Spool Settings, and select "Disable bi-directional support for this printer", and click OK.

Finally, again select the General tab, and test the installation by clicking on "Print a test page". If it works, you are finished setting up Postscript emulation. Click OK to exit the Printer Properties dialog.

(If you have problems, first check that you made the correct entries in the Printer Properties dialogs, especially check that you did not make any typing errors in the exact name for the PPA DeskJet printer in the gsprint arguments box, which must correspond exactly to the "Printer name" given to the HP PPA printer). If the problems persist, you might get guidance from the gsprint and RedMon documentation; look in the folders where these were installed.)

You now have a working emulated "Postscript printer" that can now be shared over a network. (The "sharing" options will now be available if you right-click on the emulated printer's icon.)

4.4 Limitations.

This emulated postscript printer is most useful for providing printing services to non-Windows Clients on a samba network, but can be also be used by Windows Clients with the following limitations:

  • Windows Clients will be able to select Print Settings only for the visible ("front end") "Postscript printer", but not for the hidden ("back end") HP PPA DeskJet printer that actually does the printing.
  • Changes in the local Print Settings of the PPA driver for the DeskJet printer on the Host system (but not on Client systems, if it too is shared) will affect network printing by the "Postscript printer".
  • Since the visible "Postscript printer" falsely advertises its identity, some of its Print Settings options seen by users on the Clients may not be valid.
  • The extra processing on the printer Host may make printing rather slow compared to native Windows printing.

The path entry uses /var/tmp because this is (presum- ably) a world-readable and -writable area for temporary files. After editing /etc/smb.conf to include these entries, save it, and test its syntax with Samba's testparm utility. Then restart samba (run "/etc/rc.d/init.d/smb restart" on Red Hat). 2.2. Configuring a Windows Host to share a PPA printer with non-Win- dows Clients. The Host is assumed to be a Window 98 system, and the PPA printer is assumed to be a HP722C installed with the native HP PPA drivers supplied on HP's installation CD. Some details may vary on other Windows versions. First set up a shared printer that can accept PPA input from both networked Windows Clients, and from networked non-Windows Clients that use pnm2ppa. o IMPORTANT!: A PPA printer attached to a Windows Host shared with a Client running pnm2ppa has the following limitation: o Bi-Directional communication between the Windows Host and the printer must be disabled. If it is not done, a General Protection Fault will usually occur on the Windows Host when pnm2ppa sends output to the shared printer. (A "Hpfbkg06" error occurs, and the printer becomes nonfunctional until the Windows system is rebooted.) Disabling bi-directional communication appears to be a minor inconvenience: according to HP, the print quality is unaffected, but the "advanced features of the Status Monitor" will no longer send reminders to align the print cartridges after a new cartridge is installed, or send error mes- sages associated with the ink cartridges or the banner lever. You may be able to avoid disabling bi-directional communication by using an emulated Postscript printer to serve non-Windows Clients without using pnm2ppa (see below). To turn off bi-directional communication between the Windows Host and the printer, open the Settings/Printers folder, then right-click on the printer icon, and open the Properties dialog. Select the Details tab, and click on Spool Settings, then choose the setting "Disable bi- directional support for this printer". If you have any difficulties, try rebooting Windows after the change, or see HP's support document http://www.hp.com/cposupport/printers/support_doc/bpd06455.html about disabling bi-directional communication. To set up the Host to share the printer, right-click on its icon in the Settings/Printers folder, and select Sharing, then assign it a Share Name like HP722C-PPA , and enter a Comment Line like "HP 722C printer on Windows 98 (PPA input)". You may now also wish to set up an emulated Postscript printer that accepts Postscript input from the Client, and prints it using HP's PPA drivers running on the Host, instead of on the Client. See the section Emulating a PostScript printer on a Windows Host If you have installed and successfully tested the emulated printer, set it up for sharing on the network. Right-click on its icon in the Settings/Printers folder, and select Sharing, then assign it a Share Name like HP722C-PS, and enter a Comment Line like "HP 722C printer on Windows 98 (PostScript input)". The emulated printer will appear like a Postscript printer to the Clients. If it provides acceptable printing services to the non- Windows clients, you will not need to connect pnm2ppa printers to HP722C-PPA, and will be able to re-enable bi-directional communication between the HP drivers and the printer. (However, the extra processing involved in the emulation may be unacceptably slow, or turn out to use too much of the host's CPU) 3. Configuring the Printing Clients. 3.1. Setting up Printing from a Windows Client. Open the Settings/Printers folder, and start the Add Printer Wizard. Choose to add a Network Printer, and browse the network to find the Printer Shares you configured on the host (e.g., HP722C-PPA and HP722C-PS). If they are not visible, either the Host or the network is not properly configured. Correct the problem before proceding. Normally, you will probably want to use the native Windows HP PPA drivers, so select the printer Share that accepts PPA input (e.g., HP722C-PPA). If the Host is a Windows Host, it will provide the drivers over the network, otherwise you will have to find the printer in the list of available HP Printer drivers, or click on Have Disk and install them from HP's installation CD. You then get a chance to change the name with which the printer will be known on the Client. Finally, you should choose to print a test page. You might instead (or also) want to set up printing services using the Printer Share that accepts Postscript (e.g., HP722C-PS). In that case, if the Host is not a Windows Host, choose a "generic" PostScript printer like the Apple LaserWriter II NT or the Digital turboPrintServer 20/Net. If the test page prints sucessfully, you are finished! 3.2. Setting up Printing from a Linux/Unix Samba Client First examine the network by opening a terminal window and using the command smbclient -L hostname (where "hostname" should be replaced by the network name of the Host to which the printer is attached). This will list the SMB services provided by that Host. (Alternatively, your system may have some graphical front-end to smbclient that allows you to inspect the net- work.) The list should include the Printer Share(s) you configured on the Host (e.g., HP722C-PPA and HP722C-PS). If these are absent, you must first identify and correct the problem. You must now configure the printer. The details of how to do this will vary between Linux/Unix distributions, but there will probably be support for network printing using Samba. If the Printer Share you wish to use is intended to accept PPA input (e.g., HP722C-PPA), configure the Client to use the pnm2ppa driver. If it is intended to accept PostScript input (e.g., HP722C-PS), configure the Client to print to a PostScript printer. You may wish to configure both types of printers, and experiment to see which provides the best printing services on your network. See the SMB-HOWTO documentation for more information. 4. Emulating a PostScript printer on a Windows Host. If you do not have commercial PostScript emulation software for Windows that will work with your HP PPA DeskJet (the author is unaware of any such software that supports PPA printers), you can use Ghostscript together with HP's native Windows drivers. 4.1. Installing Ghostscript as the emulation software. From the Ghostscript home page http://www.cs.wisc.edu/~ghost/ download and install (in this order) the Windows packages of o Ghostscript (PostScript Emulation Software). o GSview (Ghostscript previewer, provides gsprint). o RedMon (printer port redirection utility). (Install these using their setup.exe installation tools, and do not manually set up any configuration files for gsprint or RedMon.) You must now follow the detailed instructions below, and use the Windows "Add Printer Wizard" to add a postscript printer, and then configure it to use the gsprint utility that comes with GSview, and redirect the output to your HP PPA DeskJet using the RedMon utility. 4.2. Adding the fictitious Postscript printer. In the following, I assume your printer is a HP DeskJet 722C, and is installed with its native Windows Drivers as a printer called "HP DeskJet 720C Series". Change printer name entries below as appropriate for your printer model. The following instructions are tested on Windows 98, and may differ on other Windows variants. Open the Settings/Printers folder. First check that the HP PPA Deskjet is correctly installed, using HP's native Windows drivers. Right-click on its icon, and select its Properties dialog. The General Properties screen will open. This shows the exact name that the printer was given when it was installed. Make a note of it, and use the Print Test Page button to confirm that the printer is working. (The "Printer name:" line on the test page will also show the exact name of the HP PPA Deskjet that you will need to use when configuring the emulated postscript printer below). When you are done, click on OK to close the dialog. Now start the Add Printer "Wizard". Make the choices: o install a local printer o select a PostScript printer from the list of printers; (e.g., one of the Apple LaserWriter models: the Laserwriter II NT is known to work; Digital PrintServer models such as the turboPrintServer 20/Net have also been recommended). This will provide a suitable postscript driver. o From the list of Available Ports, choose "FILE: Creates a file on disk" (you will change this after the printer is installed) o set as default printer?: NO o Print test page?: NO 4.3. Redirecting the output to the PPA printer. After the printer has been installed, right-click on its icon, and rename it to something like, e.g., "Ghostscript+HP722C". Then right click again and open its Properties dialog. On the General tab screen, enter something informative in the Comment box, such as " Emulated Postscript printer; output redirected to a HP722C DeskJet printer" (optional). Next select the Details tab. The box "Print using the following driver:" should show the Postscript driver you selected (e.g., Apple LaserWriter II NT). o Click on Add Port. Select other, then Redirected Port, which should be available if RedMon was correctly installed, and click on OK to accept these settings and close the Add Port dialog. On the Details tab screen, The box "Print to the following port:" should now show a redirected port such as "RPT1 [Redirected Port]". o Click on Port Settings. o In the box "Redirect port to the program:", enter the path to the gsprint program. (If you accepted the defaults when installing it, this may be C:\Ghostgum\gsview\gsprint.exe; you may search for it by clicking on Browse). o In the box "arguments for this program are:" enter the arguments to be passed to the gsprint program (there is a document gsprint.htm with more details of these in the folder containing gsprint.exe). Suggested arguments are: -printer "HP DeskJet 720C Series" -color - Replace "HP DeskJet 720C Series" by the (quoted) exact name of the HP PPA DeskJet printer that you made a note of earlier. (If you do not copy this name exactly, including any capitalization or spaces, things may not work!) The -color argument is needed to enable color printing; (Whether you actually get color printing will depend on the local settings of the "HP DeskJet 720C Series" printer that really prints the document.) The final " - " is required: without it, the output of gsprint will not get redi- rected to the printer. o The box "Output" should show "Program handles output". o In the box "Run", select "hidden". o The box "Shutdown delay" will say "300 seconds". Print jobs for which processing by gsprint takes longer than this will be terminated, to avoid blocking the printer spool queue. Increase this limit if necessary. Now click on OK to close the Port Settings dialog. o Click on Spool Settings, and select "Disable bi-directional support for this printer", and click OK. Finally, again select the General tab, and test the installation by clicking on "Print a test page". If it works, you are finished setting up Postscript emulation. Click OK to exit the Printer Properties dialog. (If you have problems, first check that you made the correct entries in the Printer Properties dialogs, especially check that you did not make any typing errors in the exact name for the PPA DeskJet printer in the gsprint arguments box, which must correspond exactly to the "Printer name" given to the HP PPA printer). If the problems persist, you might get guidance from the gsprint and RedMon documentation; look in the folders where these were installed.) You now have a working emulated "Postscript printer" that can now be shared over a network. (The "sharing" options will now be available if you right-click on the emulated printer's icon.) 4.4. Limitations. This emulated postscript printer is most useful for providing printing services to non-Windows Clients on a samba network, but can be also be used by Windows Clients with the following limitations: o Windows Clients will be able to select Print Settings only for the visible ("front end") "Postscript printer", but not for the hidden ("back end") HP PPA DeskJet printer that actually does the printing. o Changes in the local Print Settings of the PPA driver for the DeskJet printer on the Host system (but not on Client systems, if it too is shared) will affect network printing by the "Postscript printer". o Since the visible "Postscript printer" falsely advertises its identity, some of its Print Settings options seen by users on the Clients may not be valid. o The extra processing on the printer Host may make printing rather slow compared to native Windows printing. pnm2ppa-1.13/docs/en/README0000644000076400007640000000312607432061647012171 00000000000000PPM to PPA converter -------------------- Copyright (c) 1998-2000 Tim Norman, Giorgio Marzano, Andrew van der Stock, and others.

Hopefully, these are fixed. - Also fixed: a memory leak affected all printer models in certain circumstances: in high quality mode, if the last data on a page was in color, the final three print head passes were not printed, and the data was left in unfreed memory. (discovered using the "valgrind" memory-leak detector). - compression of color data sent to the printer is now enabled. (only compression of black data was previously enabled). If it is suspected this is causing problems, it can be disabled by a new configuration file keyword "compression 0". - Logging of normal informational messages to the system log is now turned off by default. (They still go to stderr in "verbose" mode). Logging of information messages in the System Log can be re-enabled with a new configuration-file entry "log_info 1": this is only accepted from the default configuration file (/etc/pnm2ppa.conf). -------------------------------------------- Release notes for pnm2ppa-1.10 June 23 2002 - major rework of swath-cutting internals so black ink is never overprinted by color ink, and multipass color printing is bidirectional. Only tested on HP722C. Should have much better image quality now, we will have to see if the redesign has broken printing on HP820C, 1000C... Is anyone still using these PPA printers? - new: a --dpi300 command line option for interpreting the input as 300dpi instead of 600dpi. This may be useful for printing 300dpi pnm output directly from scanners. ----------------------------------------------------- Release notes for pnm2ppa-1.04 November 12 2000 - reduced memory footprint of calibrate_ppa from 36MB to 1.8MB - fix bug in black shearing test pattern in calibrate_ppa - fix bug in silent/vebose switches for error messages. - repair the earlier 1.01 HP820 flashing light bug fix that got broken by the 600 dot yoffset shift in 1.03... -------------------------------------------- Release Notes for pnm2ppa-1.02. 1.03 October 28 2000 - improved calibrate_ppa output, made configuration easier - change default offsets, etc. (add 600 to yoffset) - added an automated lpd setup . -------------------------------------------------- Release Notes for pnm2ppa-1.01 October 24, 2000 Fixed one more cause of "flashing light syndrome" on the HP820C. Other changes: Improved and functional calibration program, now called calibrate_ppa, incorporating Bruno Alix's calibration pages from calibrateco.c Moved the creation of "gamma.ppm" for color calibration from pnm2ppa to calibrate_ppa. All user input and syslog output was audited for security. No incorrect user input is now echoed to the syslog; syslog messages can be silenced with a new keyword "silent 1" in /etc/pnm2ppa.conf. File paths entered as user input are now handled carefully. Gamma color enhancement values can now be given as decimals in the configuration file. The various inks can be switched off in the configuration file (as an aid in troubleshooting). Release Notes for pnm2ppa-1.0 July 11, 2000 --------------------------------------------- This release is the 1.0 release of pnm2ppa. It is fully functional on all three PPA printer families, and has no known bugs. (Is "Flashing LED syndrome a thing of the past?) It can now handle all paper sizes compatible with the printer, and all pnm formats. The documentation is updated. ---- Remaining issues such as somewhat-visible horizontal swath boundaries on uniform dithered color backgrounds (such as in the ghostscript example tiger.ps) cannot be resolved without major design changes, but this should not affect most uses of pnm2ppa. (see the TODO file). Such changes will require significant effort (by someone highly motivated) to be achieved. pnm2ppa is probably as good as it can get by tweaking its code with little bug fixes. [FIXED IN v1.10] Improvements in color correction techniques could still be achieved, though (see docs/en/COLOR.txt). Calibration and printer utility procedures (head cleaning codes, etc) could also be added. (perhaps using the PUP utility?) [NOW USE calibrate_ppa FOR SOME OF THESE FUNCTIONS] Use of data compression of sweep data for color sweeps could also be added without a major rewite, to perhaps speed up printing. [FIXED IN v1.11] The pnm2ppa team. http://sourceforge.net/projects/pnm2ppa pnm2ppa-1.13/docs/en/TODO0000644000076400007640000000445507501053374012002 00000000000000TODO UPDATE (June 10, 2002) * Striping in images like ghostscript' example image "tiger.ps' has been eliminated by just making sure that black ink is never overprinted by color ink. A major reworking to cutswath.c and some improvements to image.c were needed. This is probably the final work done on this driver.. -------------------------------- Code issues (comments by duncan): * implement data compression for color as well as black and white printing. * check out the new information about the buffer on the printer. (mentioned on ppa.devel by andrew in early 2000) * cleaning head codes needed. (or put them into PUP); document the codes in the ppa docs here. * should multiple color sweeps in a swath (gMaxpass=4) alternate between right-to-left and left-to-right ? * The Windows driver also has a "normal" mode with gMaxPass=2, and well as "econofast" (gMaxPass=1) and high quality (gMaxPass=4). It alternates color passes in one direction with black passes in the other direction, at the same vertical position. If this structure is adopted, maybe the way the 600dpi resolution of black if reduced to 300dpi resolution in dither.c should be rethought. (Why not keep 600dpi black resolution ?). * A FS_black_dither routine is needed in black-only printing, for high-quality black-only images. * add autodetection of device via IEEE 1284 and other methods * redo debugging support (done ajv) * add extra .conf parameters to avoid recompiles (done: ajv & giorgio) * getopt() rather than current handling (done: ajv 19991003) Distribution and Installation issues * *BSD compatibility (partially there: ajv 19991021) * update README and all doco * update installation instructions for major distributions (caldera, RH, etc) * Translate man page into other languages * add autoconf support ? (NetBSD and alpha issues) * update CREDITS * Make install target (done: ajv) * make syslog configurable; stdout or syslog (done: ajv 19991021) CALIBRATION * CALIBRATE doco, and supporting .ps file to generate page Long Term wants * write instructions on how to speed up parallel port (Linux 2.2.x and later) * write hppaconf (KDE)? * gs native filter rather than take pnm/pbm/ppm files * scpd to monitor printer status, and provide support for console alerts (These are dumb printers, so ...) pnm2ppa-1.13/docs/pl/0000777000076400007640000000000011313235642011373 500000000000000pnm2ppa-1.13/docs/pl/CZYTAJ.TO0000644000076400007640000000215107051417471012564 00000000000000PPM -> PPA konwerter -------------------- XXX Prosimy o pomoc w pracy nad tym programem ni¿ o raporty o b³êdach w nim...

INSTALACJA ---------- Tworzy dwa pliki wykonywalne: calibrate i pnm2ppa. Calibrate - tego programu u¿ywaj do ustawienia marginesów. Wiêcej szczegó³ów znajduje siê w pliku KALIBRACJA Drugim programem jest pnm2ppa. Jest to konwerter formatu PBM na PPA. PBM jest to surowa postaæ pliku w którym zawarte s± informacje gdzie i w jakim kolorze wydrukowaæ punkt. (podstawowym programem u¿ywanym do generowania tego rodzaju plików jest GhostScript) PPA jest to natomiast protokó³ transmisji miêdzy komputerem a Win-drukark±. Standartowym rozmiarem drukowania jest 600dpi oraz rozmiar papieru US Letter. Dodatkowo program pnm2ppa rozumie formaty pbm, pbmraw, pnm, pnmraw. Ten ostatni jest najszybszy, wiêc je¶li masz mo¿liwo¶æ u¿ywaj go. U¿ywanie -------- Aby wydrukowaæ stronê postscript przy u¿yciu tego programu zosta³y stworzone skrypty. Wydruk o najlepszej jako¶ci w kolorze w rozmiarze US Letter cat $1 | gs -sDEVICE=ppmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ pnm2ppa -i - -o - | lpr w rozmiarze US Legal cat $1 | gs -sDEVICE=ppmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ pnm2ppa -i - -o - | lpr w rozmiarze A4 cat $1 | gs -sPAPERSIZE=a4 -sDEVICE=ppmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ pnm2ppa -i - -o - | lpr itd... W szczególno¶ci powinno takie rzeczy ustawiæ siê w filtrze programu drukarki (np.:lpd). Wiêcej informacji, jak to zrobiæ dowiesz siê z dokumentacji u¿ywanego filtru lub przeczytaj plik INSTALACJA.SUSE z którego dowiesz siê jak ustawiæ filtr lpd dla tekstu i plików postscript. pnm2ppa-1.13/docs/pl/INSTALACJA.SUSE0000644000076400007640000001115607051417471013433 000000000000000. Informacje Ten tekst opisuje, jak zainstalowaæ program pbm2ppa napisany przez Tima Normana w systemie S.u.S.E Linux System. Ten program wykorzystuje GDI (dla Windofsow) daj±c mo¿liwo¶æ korzystania z drukarki w systemie Linux. Aktualnie program jest konwerterem pomiêdzy formatem PBM (np. tworzonego przez GhostScript) a formatem PPA zjadliwym dla win-drukarek z serii 710/720, 820 i 1000. Do druku najwygodniej jest u¿ywaæ GhostScripta, któremu zlecamy zrobienie pliku pbmraw (mo¿e te¿ byæ pbm, ale za to wolniej bêdzie siê to drukowaæ). Z drukowaniem samego tekstu jest roboty. Z racji tego, ¿e drukarka go nie zrozumie musimy zamieniæ tekst na format postscript i zrobiæ jak napisa³em akapit wy¿ej. Zamiany tekstu ascii na postscript wykonuje program enscript. Nie jest to proste ale nie panikuj. Autor dla wygody stworzy³ dwie drukarki w spoolers (nie bêdê siê mêczy³ aby to przet³umaczyæ...), jedn± dla plików ps, drug± dla plików ascii. Instalacja tego ustrojstwa to tylko 7 kroków. 1. Instalacja pakietu ppa-0.8.5 Pobierz pakiet ze strony http://www.rpi.edu/~normat/technical/ppa/ i sk±piluj wpisuj±c: # make XXX (gdzie XXX to numer twojej win-drukarki, czyli 720,820 lub 1000. Je¶li masz drukarkê z serii 710 to u¿yj opcji dla 720-stki. U mnie dzia³a...) 2. Ustaw papier na A4 u¿ywaj±c opcji -s A4 w programie pbm2ppa lub w pliku pbm2ppa.conf wpisz "papersize a4" (patrz te¿ pkt.5) 3. Kalibracja. Dla rozmiaru US wpisz # pbmtpg | pbm2ppa > /dev/lp1 ( jako root ) Dla rozmiaru A4 wpisz # pbmtpg -a4 | pbm2ppa -s a4 > /dev/lp1 ( jako root ) 4. Teraz mo¿esz drukowaæ pliki postscript u¿ywaj±c nastêpuj±cego pliku shella: cat $1 | gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ pbm2ppa - - >/dev/lp0 Je¶li zapiszesz to w pliku "print" (po oczywistej zmianie - chmod 755 print) mo¿esz ju¿ drukowaæ pliki ps wpisuj±c # print nazwapliku.ps Je¶li zale¿y Ci na drukowaniu plików ascii to przepisz ten skrypt: enscript -2rj -p- $1 | \ gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ pbm2ppa - - >/dev/lp1 Je¶li zapiszesz to w pliku "printascii" (po oczywistej zmianie - chmod 755 print) mo¿esz ju¿ drukowaæ tekst wpisuj±c: # printascii nazwapliku.ascii (Uwaga: Parametry w tym skrypcie dla enscript s± ustawione na drukowanie tekstu w dwóch kolumnach. Wiêcej informacji dotycz±cych konwersji ascii->ps przeczytasz w instrukcji programu enscript.) 5. Mo¿liwe, ¿e powiniene¶ przekalibrowaæ swoj± drukarkê (patrz pkt.3) Oto instrukcje w jaki sposób ustawiæ drukarkê aby poprawnie drukowa³± pliki ascii przy u¿yciu skryptu printascii (patrz pkt.4) Program pbm2ppa pobiera argumenty w podanej kolejno¶ci: a) z lini poleceñ b) z pliku konfiguracyjnego /etc/pbm2ppa.conf c) z ustawieñ w pliku nag³ówkowym "default.h" Najwygodniejszym rozwi±zaniem jest odpowiednia zmiana pliku konfiguracyjnego. Oto przyk³ad jak to zrobiæ (/etc/pbm2ppa.conf): # Przyk³adowa konfiguracyjna dla HP720 i papieru A4 # version 720 papersize a4 xoff 0 # \ Ustaw to dla swojej drukarki. yoff -600 # / (patrz plik KALIBRACJA) # 1/4 cala marginesu z ka¿dej strony (dla 600 DPI) # mo¿esz wpisaæ swoje warto¶ci... top 50 bottom 50 left 50 right 50 6. Aby zescaliæ konwerter z systemem Linux tworzymy dwie drukarki w pliku /etc/printcap. Jedna z nich obs³uguje postscript, druga pliki ascii. Oto co wpisaæ do pliku /etc/printcap: lp:\ :lp=/dev/lp1:\ :sd=/var/spool/lpd/lp:\ :lf=/var/spool/lpd/lp/log:\ :af=/var/spool/lpd/lp/acct:\ :if=/usr/local/bin/ps.if:\ :la:mx#0:\ :sh:sf: ascii:\ :lp=/dev/lp1:\ :sd=/var/spool/lpd/ascii:\ :lf=/var/spool/lpd/ascii/log:\ :af=/var/spool/lpd/ascii/acct:\ :if=/usr/local/bin/ascii.if:\ :la:mx#0:\ :sh:sf: Teraz trochê wyja¶nieñ. U¿ywamy standartowo portu /dev/lp1. Wykorzystujemy równie¿ katalogi /var/spool/lpd/ascii oraz /var/spool/lpd/lp (najlepiej stwórz je teraz). Aby po³±czyæ konwerter pbm2ppa z systemem stworzyli¶my dwa filtry. Aby zaczê³o to dzia³aæ nale¿y jeszcze stworzyæ dwa pliki: Plik /usr/local/bin/ascii.if: #! /bin/sh enscript -2rj -p- | \ gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ /usr/local/bin/pbm2ppa - - Plik /usr/local/bin/ps.if: #! /bin/sh gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ /usr/local/bin/pbm2ppa - - 7. Przekopiowaæ program pbm2ppa do /usr/local/bin. Teraz aby wydrukowaæ plik wpisz: # lpr nazwapliku.ps lub # lpr -P ascii nazwapliku.ascii I to na tyle. 19.

XXX Spróbuj sam, mo¿e Tobie siê uda... XXX Kalibracja (ustawianie) pnm2ppa dla Twojej drukarki Zanim zaczniesz drukowanie powiniene¶ skalibrowaæ drukarkê. Mo¿na to zrobiæ u¿ywaj±c programu 'calibrate'. Proces ustawiania polega na wydrukowaniu strony testowej o maksymalnym rozmiarze. Ca³a zabawa polega na takich ustawieniach marginesu w pliku konfiguracyjnym, aby ca³a strona by³a wydrukowana w ca³o¶ci. Program 'calibrate' jest prosty jak drut. Wyrzuca na wyj¶cie wzór testowy w formacie pbmraw. Gdy skierujemy to co wypluje 'calibrate' do programu pnm2ppa przy u¿yciu komendy: calibrate | pnm2ppa > /dev/lp1 ( jako ) - lub - calibrate | pnm2ppa | lpr -l ( je¶li Twoj filtr drukarki rozpoznaje parametr '-l') Wydrukowana strona powinna zawieraæ siatkê oraz liczby okre¶laj±ce wspó³rzêdne pikseli. Na nieszczê¶cie pierwsze wydruki obcinaj± wydrukowan± stronê przy brzegach strony. Je¶li tak siê dzieje powiniene¶ ustaliæ marginesy w pliku konfiguracyjnym /etc/pnm2ppa.conf. Podane tam warto¶ci podane s± w jednostkach punktów na cal. Czyli je¶li podamy tam warto¶æ np. 100, bêdzie to 100/600 cala (rozdzielczo¶æ druku 600dpi) czyli 1/6cala.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

The # setting "verbose 1" sends messages to the standard error stream (stderr) # in addition to the syslog. (Note: if pnm2ppa was compiled with the # -D__NO_SYSLOG__ option (e.g., for BeOS), syslog messages are # diverted to stderr; use "silent 1" to suppress them.) #silent 1 #verbose 1 # (NEW FEATURE:) # standard informational messages ( when a job starts, when each page # prints, job finished, etc.) will not be recorded in the System Log, # unless explicitly activated here with the "log_info 1" keyword. # (i.e., "log_info 0" is the default.) # (Informational messages will still always be sent to stderr in "verbose" # mode, even if log_info is not set.) log_info 1 # <= COMMENT THIS OUT TO GET THE NEW DEFAULT BEHAVIOR! # Note: the "silent 1" and "log_info" keywords are only accepted from the # system configuration file (/etc/pnm2ppa.conf), and not from configuration # files specified by users with the pnm2ppa option "-f". #---------set the margins of the printed page------------------- # Margins: these are distances from the edges of the paper in # "dots" ( 600 dots = 1 inch = 2.54 cm). # Nothing outside these margins will be printed. # Default values are give below; uncomment and change, if necessary. # (Older versions of pnm2ppa required larger left and right margins to avoid # printer failure with "flashing lights", but this problem is believed to # be solved) #topmargin 10 #bottommargin 150 #leftmargin 10 #rightmargin 10 #----------center the printer output on the paper------------------- # Offsets: these are adjustments for centering the print correctly on the # paper. Units are dots (1/600 inch). Add a positive number of dots to # xoff to move the printed image to the right, relative to the paper. # add to yoff to move it down. The helper program calibrate_ppa prints # a test page to check the offsets (see CALIBRATON.txt): # usage: "calibrate_ppa --center | pnm2ppa --bw - - | lpr -l # Default values are: #xoffset 160 #yoffset 50 #------------align the black and color ink cartridges-------- # Color Offsets: these control alignment between the black ink # and color ink print cartridges. This changes a little whenever you # replace an ink cartridge, so the default values are just approximate. # # Use "calibrate_ppa --align | pnm2ppa --fd - - | lpr -l " # to print a test page to help you adjust the color offsets. # # The first line checks horizontal alignment ColOffsX,: # The second line checks vertical alignment ColOffsY,: # The alignment is correct if alignment patterns "0" is best. # If a diffent alignment pattern is best, add or subtract the + or # - value shown below it to ColOffsX or ColOffSy. # # See CALIBRATION.txt for more details. # Use "calibrate_ppa --test | pnm2ppa --fd - - | lpr -l " to check your # new settings. #ColOffsX 0 #ColOffsY 0 #---------------"shearing" corrections------------------------------------- # shearing correction (for bidirectional printing modes) # if there is a horizontal offset between right-to-left and left-to-right # sweeps of the print head, adjust these in units of 1"/600 (1 dot). # There are separate corrections colorshear and blackshear for the # color and black print heads. The third and fourth lines of the # alignment test page (see above) tests these. # The setting is correct when alignments "0" are correct. # The (positive or negative) number shown under the best-aligned shearing # alignment pattern tells you how much to change the colorshar or blackshear # value by. (For, example, if you print the calibration page with # "colorshear 0" (the default value) and the best pattern is labelled "-2", # uncomment the "colorshear" value below and set it equal to -2.) #colorshear 0 #blackshear 0 #-------------blackness control----------------------------- # this controls the density of black ink used. # valid blackness choices are 1 2 3 4; controls the # density of black ink used: 1 (least ink), 2 (default), 4 (most). # 0 = no black ink. This affects black ink bordered by whitespace # only (e.g. text, but not black in color images) #blackness 2 #------------Color correct curve Gamma parameters------------------------- # Gamma color correction values for Red, Green and Blue: # (Note: a more effective method of color correction is to use # a calibration file /etc/pnm2ppa.gamma, in which case these # Gamma values will not be used. See COLOR.html or COLOR.txt) # The pnm2ppa option --noGamma suppresses color correction. # The standard Gamma enhancement curve is # gEnh(i) = (int) ( pow ( (double) i / 256, Gamma ) * 256 ) # (i.e., 256 times ( i*(1.0/256)) to the power Gamma ), # where (int) i is the ppm color intensity, in the range 0 - 255. # positive values of Gamma enhance (increase the intensity of) # the corresponding color. Gamma = 1.0 corresponds to no # color correction, gEnh[i] = i. # You can specify Gamma values as a decimal number for each primary color #GammaR 1.0 # red enhancement #GammaG 1.0 # green enhancement #GammaB 1.0 # blue enhancement # For use with the printed output of "pnm2ppa -g ", # you can also specify Gamma values using the integer GammaIdx, # which gives Gamma = 1.0 - 0.033 * GammaIdx : #RedGammaIdx 0 #GreenGammaIdx 0 #BlueGammaIdx 0 # Default papersize (only used for printing the color calibration # test page with pnm2ppa -g). # Valid choices are: a4, letter, legal: #papersize letter # this is the default #papersize legal #papersize a4 #-----------suppress bidirectional printing--------------------- # by default the printing sweeps are now bidirectional (unimode 0); # to make unidirectional printing (left-to-right) the default behavior, # (unimode 1) uncomment the next line . (The command line options --uni # and --bi override the default behavior).

(duncan, Feb 12 2000, updated July 2000) - The entries in line[] are written by one of the functions FS_Color_Dither(), HT_Color_Dither(), HT_Black_Dither() in dither.c - The entries in line[] represent the ( image->width ) pixels on a line. Each pixel is represented by three consecutive entries (line[i] , line [i + 1] ,line [i + 2] ) , where i = 0, 3, 6 , ... , < (image->width * 3) The three entries correspond to Cyan, Magenta, and Yellow ink. - entries in line[] take values 1, 2,...,(gMaxPass + 1) , 0 or 255, where gMaxPass is the maximum number of passes of the color print head. * gMaxPass is only used in Color mode (gColorMode=true) * In normal color mode (gEcomode=false, gFastmode=false) gMaxPass = 4 * In Economy mode (gEcoMode = true) gMaxPass = 1 * In Fast Color mode (gFastMode = true) gMaxPass = 1 - values line [] = 1, 2, ..., gMaxPass correspond to gMaxPass, gMaxPass-1, ..., 1 drops of ink of a given color (C, M,or Y). - the value line [] = 0 also means gMaxPass drops of ink - the value line [] > gMaxPass (usually = gMaxPass+1 or 255) means 0 drops of color ink. - an entry (0, 0, 0) corresponds to a black drop, which can either be a drop of black ink, or gMaxPass drops each of C,M and Y ink, If this is implemented with a drop of black ink, convert_black_data() changes (0,0,0) to (255,255,255), so it won't get repeated using colored ink by the following call to convert_color_data(). - whitespace is coded by (255,255,255). - triplication of bytes is switched off when gByteCount == 1 Color data is only printed on even lines. Black data is printed on even and odd lines, except in Black-and-White Economy mode (gColorMode=false, gEcoMode=true), when only even lines of black are printed.

Both MAXLINES and Max Buf Lines must agree. 20000120 klamer Patches to allow calibration to work again. mancini BeOS support duncan RedHat Print filters added to CVS tree ajv Fixed -v and moved yet another global into a struct 20000306 duncan Lots of little fixes; --fd working right now; bidirectional shearing adjustments added (user configurable entries "blackshear" and colorshear" in pnm2ppa.conf. 20000311 duncan added : -B n option and "blackness n" config file entry to control black ink density (drops per pixel n = 0,1,2,3,4 ) default is 2. Also there are now config file entries blackshear and colorshear for adjusting shearing in bidirectional printing. Fixed various bugs that broke HP820/1000 printing. 20000318 duncan Color EcoMode printing now uses bidirectional printsweeps (formerly only FastMode did this) If gMaxPass = 1, you now get bidirectional sweeps (in cut_im_color_swath() , cutswath.c) 20000326 duncan ** changes to dither.c: on odd lines, black is now processed (not color), even black pixels are duplicated, so if either of two successive pixels are black, they both are. Changes also fix Tim's report about blurry black/white boundaries. ** changes to image.c If the odd line is not printed (PixMap or EcoMode), image.c now stores the line, and adds the black parts to the next even line. This fixes a bug in where thin (one-pixel wide) black lines (like enscript borders) could be lost because black ink only printed every second pixel, and odd black lines were just copies of the preceeding even line which had been stored. 20000331 duncan added support for large papersizes 11x17 and a3 (for the 1000 series printers). Added a printer-specific max_pagewidth so papersizes that are too wide for a printer series will not print on that printer. 20000402 duncan tweaked bidirectional sweep shearing correction. (removed the +1 right-to-left black shift in cut_im_black_swath() in cutswath.c ). I am not sure if the shearing correction is model or individual printer-specific. (I suspect the second case, in which case it is a calibration issue (The HP Win9x software seems to have calibration adjustments for blackshear.) if any corrections turn out to be generic to a given printer family, (rather than specific to a particular printer) the default can be changed in defaults.h (the variables are: printer->r2l_bw_offset (=blackshear) printer->r2l_color_offset (=colorshear). 20000404 duncan added support for pbmraw and pgmraw formats. all three pnmraw formats now work. (changes in image.c, image.h ) 20000405 duncan added support for pgm, ppm, pbm nonraw formats. added papersize autoconfiguring from the pnm header, so all ghostscript papersizes are now supported (if the printer can accomodate them) The -s option now only controls the gammafile creation papersize. Made bidirectional printing the default (but this can be configured with a "unimode 1" in pnm2ppa.conf, or --uni, --bi command line options. 20000408 duncan graceful termination of print run if pnm input is truncated (i.e., if read_line() encounters EOF). printer no longer hangs. Moved text strings to lang.h/text-en.h 20000423 duncan clean up way things near sides of swath are handled in cutswath.c 20000710 duncan in FS_Color_Dither(), use line[]= (1,1,1) not (0,0,0) for black replacement of dark pixels for which no color match is found. (fixes flashing LED on certain images - those with no black - with --eco on HP820) (0,0,0) = black ink, (1,1,1) = gMaxPass drops of each color. 20000928 duncan in cutswath.c, if the vertical position of the black and color sweeps differed by 1 , 2 or 3 dots, HP820 got "flashing light syndrome". Fixed by testing for this possibility, and if found, by reducing numlines, and padding the top of a swath with an (even) number of blank lines to keep the height the same. (Thanks to Steven Elliott for reporting this bug, and testing the fix. 20001010 ajv made input of paths to gamma and config files secure against buffer overruns. duncan In -g mode, check that gamma.ppm is not a symbolic link, and is a regular file, before writing to it (but after opening it). 20001018 duncan clean up calibration program. now called calibrate_ppa. It does most calibration now. moved the job of writing gamma.ppm for color calibration to a new utility calibrate_ppa.c. pnm2ppa -g now just prints the corresponding test page. secured syslog messages. No user input is sent to syslog. syslog messages are wrapped, and can be suppressed with a new keyword "silent 1" in /etc/pnm2ppa.conf (but not in subsequently-read config files). all syslog activity now occurs in syslog.c. 20001106 reduce memory footprint of calibrate_ppa (it was 36MB!). 20001112 fix syslog silent/verbose usage; fix alignment pattern bug in calibrate_ppa. repaired the HP820 fix that got broken when the vertical offset was redefined by 600 dots... 20010829 duncan Change the preprocessor flag __BEOS__ to __NO_SYSLOG__ as it is not BeOS specific (it supresses use of the System Log) Added Makefile entries for Solaris, and an INSTALL.SOLARIS file. 20020211 duncan Cleanup C++-style comments (gives gcc compiler warnings) Small syslog.c/Makefile cleanups for Solaris. Minor documentation updates. Change a confusing syslog message about "unsupported PNM formats" so it is clear that the error was non-PNM input to pnm2ppa. Increase version to pnm2ppa-1.10 20020224 duncan Reworked cutswath.c and ppa.c so print sweeps are sent separately by ppa_print_page() in cutswath.c to ppa_print_sweep() in ppa.c (until now, they were going in groups of gMaxPass= 4 at a time in color high quality mode) This will now permit improvement of the print sweep pattern, and make the code easier to understand (easier to separate ppa stuff from image stuff) if someone wants to do a gimp-print PPA backend. 20020311 duncan lots more (incremental) reworking of cutswath.c; now it's pretty well modularized, reading the input image constructing the sweep data, constructing the nozzle data, are all done in separate functions now. Also, modified image.c so the the expansion of data to ppm format (three bytes per 8 dots) is not done for pgm or pbm input (unless the -p option which uses colored ink to make black, and disbles the black ink is used). a new global variable gByteCount = 1 or 3 distingushes the two types of intermediate data format. Also still TODO: I finally understood that the striping of black parts of the image when e.g. the gs example file "tiger.ps"is printed in high-quality mode is because the color and black sweeps are not aligned, so sometimes the color prints on top of black, sometimes the color prints underneath black. If both types of ink are to be used at the same place, the simple solution is probably to prevent black sweeps getting ahead of unprinted color in ppaprint_page() in cutswath.c. 20020526 duncan solved the striping problem; reworked cutswath.c so black ink is never overprinted by color ink. 20020601 duncan reworked the code that prevents color swaths and black swaths from having vertical_pos that differs by 1, 2 or 3 lines (needed for HP820C). (to go with the new swath-cutting algorithm). Added a method for recognising if input is a calibration page produced by calibrate_ppa, as these dont work correctly with the new swath-cutting algorithm. (will restore a "legacy-style" (pnm2ppa-1.04-style) method for printing input that is detected to be calibration pages) 20020610 duncan added a method for storing info on lines as they are read from the image. (whether they have black, and/or color data, etc.) Helps a lot! final fixes to calibrate_ppa. new code seems to work 20020623 duncan added a new command line option --dpi300 that interprets input resolution as 300dpi instead of 600dpi 20020930 duncan enable compression of (color) data by default (only compression of black data was previously enabled). added a configuration file keyword "compression" to switch it off, in case there are problems ... (color data compression seems to work on HP722C!) 20021005 duncan disable logging of informational syslog messages by default. They can (only) be reenabled by "log_info 1" in the default configuration file /etc/pnm2ppa.conf. (They will still go to stderr in "verbose" mode). 20021109 duncan make "version 0" in the config file set the printer type to NOPRINTER, and abort printing if this is not subsequently set to a valid printer model. 20091210 jrbeis fix getopt_long() usage for PowerPC Change the local file syslog.h to ppa_syslog.h to avoid any interference with the global syslog.h. 20091212 jrbeis Autotoolize the package, but do not change other code pnm2ppa-1.13/README.security0000644000076400007640000000717007342473416012511 00000000000000These notes are for the guidance of distributions that include pnm2ppa: --------------------------------------------------------------------- Notes on secure installation of pnm2ppa. What pnm2ppa does: 1. It attempts to open and read a configuration file "/etc/pnm2ppa.conf", and then any additional configuration files with paths specified by the -f command line option. These paths are checked to be shorter than MAXPATHLEN before they are used, otherwise pnm2ppa terminates. GNU getopt() is used to process options. 2. It opens an input file (-i option) to receive pnm data. The pnm format and page size is taken from the header. If the header does not correspond to a valid pnm format, the rest of the data is rejected, and pnm2ppa terminates. The input file path is checked to have a length less than MAXPATHLEN, as determined at compilation time. 3. It opens an output file (-o option) to send ppa data (for the printer). The output file path is checked to have a length less than MAXPATHLEN. 4. (unless the --noGamma option is specified) it tries to read color correction data from "/etc/pnm2ppa.gamma", or an alternate file with a path specified by the -F command line option. Such paths are also checked to be shorter than MAXPATHLEN before they are used. If this data exists, but is not successfully read, pnm2ppa terminates. (See COLOR.txt). 5. pnm2ppa opens and writes to the syslog with informational messages about its progress, or, if it terminates, with an error message. If it is working in --verbose mode, these messages are also sent to stderr. No strings derived from user input to pnm2ppa are included in syslog messages. Syslog messages must fit in a string of length < 128. They can be suppressed with a keyword "silent 1" in the default system configuration file (/etc/pnm2ppa.conf), but not from user-specified config files (from -f option). All syslog actions by pnm2ppa are "wrapped": message strings produces in the rest of the program are only sent to the syslog by code in syslog.c. This is also where openlog() and closelog() are called. ---------------------------------------------------------------------- Recommendations: -- do *NOT* install pnm2ppa suid/guid, if is possible that a "malicious user" might run it. The output file specified with the -o option could overwrite files to which the user has no write permission. -- since pnm2ppa works as an output filter for gs, it only needs the same privileges that gs would need. If lpr is available, pipe the pnm2ppa output though "lpr -l ..." to the appropriate printer rather than directly sending it to e.g. /dev/lp0 (in the latter case, write privileges on /dev/lp0 would be needed.) -------------------------------------------------------------- Other (optional) programs in the distribution: Do NOT install these suid/gid! calibrate_ppa.c: This is used to produce various ppmraw format PixMap images used with pnm2ppa for printer calibration. Note: these PixMaps are LARGE (100MB!!) and should generally be piped directly to pnm2ppa. THIS SHOULD USUALLY BE INSTALLED. parse_vlink.c a utility useful in debugging pnm2ppa that can interpret ppa format output instructions to the printer, whether produced by pnm2ppa, or captured from the Windows9x drivers. It is in the ppa_protocol subdirectory, and is not compiled by default. THIS IS NOT USUALY INSTALLED. pnm2ppa-1.13/pdq/0000777000076400007640000000000011313235642010614 500000000000000pnm2ppa-1.13/pdq/README.pdq0000644000076400007640000000362607505653400012206 00000000000000gs-pnm2ppa is a driver that integrates pnm2ppa into Jacob Langford's simple spool-free printing system PDQ ("Print, Don't Queue"). It will work for the following printers that use the PPA protocol: HP DeskJet 710C, 712C HP DeskJet 720C, 722C HP DeskJet 820Cse, 820Csi HP DeskJet 1000Cse, 1000Csi The printer must be installed LOCALLY on the host that runs pdq; translation to the PPA format that the printer accepts must be done on the host to which the printer is physically attached. gs-pnm2ppa cannot be used to print to a PPA printer that is accessed over a network. ------------------------------------------------------------- PDQ currently has a homepage at: http://pdq.sourceforge.net The latest release (as of September 2000) is pdq-2.2.1. ------------------------ After installing a version of pdq that does not include this driver, just copy the file "gs-pnm2ppa" into the pdq ghostscript driver directory (usually /etc/pdq/drivers/ghostscript/), and the file "dummy" into the interfaces directory (usually /etc/pdq/interfaces). You must be root to do this: cp gs-pnm2ppa /etc/pdq/drivers/ghostscript cp dummy /etc/pdq/interfaces Then run "xpdq" to setup the printer, selecting the driver "gs-pnm2ppa", and the interface "dummy". You must specify The local parallel printer port to which the printer is attached when configuring the driver. You must then return to the "driver option" screen and select the correct printer model and desired color mode. You may need to exit xpdq to activate the settings you just entered. Note that the user of the printer must have write permission to the port it is attached to. Thats all!. ------------------------------------------------------------------ The pnm2ppa homepage is at: http://sourceforge.net/projects/pnm2ppa send comments/bug reports about gs-pnm2ppa (but not pdq) to: pnm2ppa_advice@users.sourceforge.net pnm2ppa-1.13/pdq/dummy0000644000076400007640000000227007157616403011620 00000000000000# Copyright 2000 Duncan Haldane # # PDQ interface: dummy # # This program is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License version 2. # # This program is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY # or FITNESS FOR A PARTICULAR PURPOSE.

(For older Red Hat or Mandrake systems, you may need to rebuild the source RPMs.) These RPMS already incorporate the changes described here, so just install the appropriate one. ------------------ (2) If you have printtool 3.44 or greater, but rhs-printfilters >= 1.61 and < 1.72 (Red Hat 6.2, Mandrake 7.1) you may wish to manually update the files /usr/lib/rhs/rhs-printfilters/printerdb /usr/lib/rhs/rhs-printfilters/ppaprint as described here. This will provide improved functionality of pnm2ppa configuration using printtool. (3) Future releases of Red Hat or Mandrake will probably include rhs-printfilters >= 1.72, so these changes will already be made. ================================================================= Instructions. (Red Hat 6.2, Mandrake 7.1) (a) replace /usr/lib/rhs/rhs-printfilters/ppaprint . (as root:) cd /usr/lib/rhs/rhs-printfilters copy ppaprint-latest and printerdb-ppa to this directory, if necessary. (if you installed pnm2ppa-1.0 from a RPM they should be there already). mv ppaprint ppaprint-old mv ppaprint-latest ppaprint chmod 0755 ppaprint (b) update printerdb. Save your current printerdb: cp printerdb printerdb-saved Now edit printerdb to replace the PPA printer entries with the updated ones from printerdb-ppa. Use your favorite editor to cut out the older PPA printer entries from printerdb, and paste in the contents of printerdb-ppa in their place. **TIP: for this to work, the PPA Printer entries in your old printerdb must say "GSDriver: ppa" and *NOT* "GSDriver: pnmraw" (which is an older printerdb style meant for printtool < 3.44). "ppa" is not a true GS driver name, but a dummy device name added to the list of available drivers by printtool >= 3.44 after it has detected that pnm2ppa is installed. ------- Note that these manually-made changes may be lost whenever the rhs-printfilters rpm is updated using the rpm utility. Eventually, they will be incorporated in newer "official" releases of rhs-printfilters-1.72 or above, as they are released. pnm2ppa-1.13/rhs-printfilters/ppaprint0000755000076400007640000000773707204420653015066 00000000000000#!/bin/sh # ppaprint v2.12 July 7, 2000 # # make pnm2ppa (or pbm2ppa) command line for postprocessing to produce PPA # output for HP's PPA printers (DeskJet 710, 720, 820, 1000 series). # # Duncan Haldane, the pnm2ppa project, # see also http://sourceforge.net/projects/pnm2ppa # BINDIR=/usr/bin CONFIG_DIR=/etc PPA_CONFIG=$1 PAPERSIZE=$2 RESOLUTION=$3 EXTRA_GS_OPTIONS=$@ for arg in $1 $2 $3 ; do EXTRA_GS_OPTIONS=$(echo "${EXTRA_GS_OPTIONS}" | eval "sed -e 's/^.*$arg//'") done if !

Protocol

Copyright © 1998 Tim Norman

Disclaimer: This information may not be accurate. It has been compiled by me from experimentation and other means that may be prone to error.

The PPA protocol is actually composed of two protocols: a lower-level packet protocol called VLink and the Sleek Control Protocol (SCP). The VLink protocol regulates all data transfered back and forth between the printer and the computer. SCP sends command sequences to tell the printer to do things like load a sheet of paper, eject, and print a sweep.

Although PPA is a bi-directional protocol, I have mainly concentrated on its uni-directional component. It is not required for the host to be aware of the bi-directional nature of the device, which makes this easy to do.

All values are stored in big-endian format.

Note added: the utility program parse_vlink is a simple utility to step through the individual Vlink packets in a PPA stream. It also decodes the SCP packets and prints the information encoded in them.

VLink

VLink is a very simple protocol:

BytesDescription
1The character '$'
1Channel. Several channels are used:
0Image Data
1Commands and responses
2Autostatus
128Periodic Ring Buffer Pacing
2Length of packet
nPacket data

When image data is sent over the image data channel, it takes a form that is very close to how it is presented to the print head mechanism. The code in ppa.c best describes how this data is organized. I will also attempt to explain the PPA sweep data.

The image data may also be optionally compressed. I have not yet worked out the details of the compression method, though it seems similar to the compression used for the PCL protocol. My code currently generates uncompressed data only.

Note that there is a limit to the amount of data that can be sent to the printer. If you overflow that limit, the printer will get confused. This is why print_pbm uses only 150 of the 300 black nozzles; using all of them would overflow the printer's data buffer. I hope to improve this in the future with compression and multiple sweeps per line. This limit is somewhere around 100k for the Deskjet 820Cse.

(added 09/28/2000, by duncan_haldane@users.sourceforge.net): Printing on HP820 with pnmn2ppa-1.0 fails with flashing lignt syndrome if the vertical position of two successive sweeps differs by 1, 2, or 3 dots. (This was observed for the case when one sweep is black , the other is color). If the two sweeps have the same vertical position (as in Windows 9x printing, its OK)

SCP

SCP is the protocol that controls the printer's actions. I will describe several of the commands that I use in my software.

It appears that SCP differs depending on the series of printer that is being used.

HP 720 SCP protocol

Following is the probable specification for the SCP protocol on 720 printers. Thanks to Jim Peterson and Ben Boule for much of this information.

BytesDescription
2Command specifier
2Packet length (N)
1Priority
1Blank (always zero)
2Command reference number
4Number of channel 0 bytes this packet processes
4Always (00 02 00 00) - version number?
N-16Data, including parameters to this command

Several of the commands are described below:

CS=0x186, CR=1 (INIT_COM ?)

This is some sort of initialization command. It probably initializes the communications channel, since it is always the first packet sent by the windows driver. It's data consists of 8 bytes that I have only seen as:

  00 00 01 F4 01 00 00 00

CS=0x18F, CR=2 (INIT_DATA ?)

This is another initialization command. It is sent once at the beginning of each file printed, after the INIT_COM packet. It is preceded by a 4-byte VLink packet sent to channel 0. This suggests that it somehow initializes the data channel of the printer (thus our temporary name). This packet typically contains the values: DE AD BE EF. The data portion of this command usually contains the following 8 bytes:

  DE AD BE EF 02 00 00 00

CS=0x183, CR=1 (INIT_PAGE ?)

This command is sent each time before a page is loaded. It appears to set some parameters for the page, possibly the minimum and maximum horizontal positions for each of the four pens (?). The only data I have seen it contain is the following:

  28 2D 00 41 2D 32 00 46  2D 32 00 46 2D 32 00 46

CS=0x181, CR=1 (HANDLE_MEDIA)

This is the command that handles loading and ejecting of pages.

11=load, 2=eject
1?? usually 0x01
2usually 0x12C0 (4800 decimal), perhaps the horizontal position to place the print-head while loading/ejecting the page. 4800 corresponds to 8" from the left.

CS=0x180, CR=1 (PRINT_SWEEP)

This is the print sweep command. It causes the print head to print a sweep of data (which has previously been sent over channel 0).

The PRINT_SWEEP command controls the print head while printing data on a page. It can take on two forms, one when printing with the black nozzles, and one when printing with the color nozzles. The black form is described in the most detail here, since it is what I have devoted the most attention to.

Following is the format of the first 48 bytes of data for this command:

BytesDescription

11 = compressed, 0 = not compressed
12 = left-to-right, 1 = right-to-left

Following this header are sets of 16-byte rows to describe how to handle the nozzles. The odd nozzles are described by the first row, and the even nozzles are described by the second row.

Sweep data explanation

It took me quite a while to understand the explanation of the sweep data from the HP Journal articles, so I will try to explain it in a little clearer terms here.

The swing buffer separation applies for black as well as CMY sweeps. I have only deciphered the ordering for the black data, however.

What's a sweep?

Let's first start off by describing how the nozzles on the printhead are arranged.

For the black nozzles, there are 300 total nozzles. They are numbered from 1 to 300. There are two columns of nozzles - odd and even. The odd colum consists of 150 nozzles separated by 1/300 of an inch. The even column is similar, but it is shifted down 1/600 of an inch from the odd column. Thus, we can get 300 dpi by printing with one column and 600 dpi by printing "between the lines" with the other column.

For the color nozzles, each color (CMY - cyan, magenta, yellow) has 64 nozzles. They are split into two columns of 32 nozzles each. The odd column has nozzles separated by 1/150 of an inch, and the even column has the same set of nozzles, but shifted 1/300 of an inch down. This allows us to get 300 dpi color. (This may differ slightly on printers other than the 820Cse)

When the printer prints a graphical image, it must convert the image data into a form that it can understand. The first task is to separate the image into swaths. Let us assume that we have a black-and-white bitmap that is X pixels wide and Y pixels tall that we want to send to the printer. We must cut this into several swaths, each of a certain height. For example, we might choose to cut it into swaths that are 300 pixels high (1/2 an inch). This produces a series of bitmaps that are X by 300 pixels in dimension.

With this swath data, we can now produce a series of sweeps. A sweep is simply a set of data that tells the printhead how to move across the page and what data to print. For each swath, there may be only one sweep, or there may be multiple sweeps.

Formatting the sweep data

The sweep data is formatted in a very specific way so that the printer can understand it. The first thing that we need to do is convert the bitmap data into the correct form. The form that is required looks like this:

Columns 0-7Columns 8-15... Columns ceil(X/8)*8-8 to ceil(X/8)*8-1
Byte 0Byte 1...Byte ceil(X/8)-1
Byte ceil(X/8)Byte ceil(X/8)+1...Byte 2*ceil(X/8)-1
............

Each of the 8 bit values are packed into a byte in big-endian order.

To give a more concrete example, assume we have a sweep that is 64 pixels wide and 8 pixels tall. Here is what our data organization will look like:

Col 0-7Col 8-15Col 16-23Col 24-31Col 32-39Col 40-47Col 48-55Col 56-63
Row 0 Byte 0Byte 1Byte 2Byte 3Byte 4Byte 5Byte 6Byte 7
Row 1Byte 8Byte 9Byte 10Byte 11Byte 12Byte 13Byte 14Byte 15
Row 2Byte 16Byte 17Byte 18Byte 19Byte 20Byte 21Byte 22Byte 23
Row 3Byte 24Byte 25Byte 26Byte 27Byte 28Byte 29Byte 30Byte 31
Row 4Byte 32Byte 33Byte 34Byte 35Byte 36Byte 37Byte 38Byte 39
Row 5Byte 40Byte 41Byte 42Byte 43Byte 44Byte 45Byte 46Byte 47
Row 6Byte 48Byte 49Byte 50Byte 51Byte 52Byte 53Byte 54Byte 55
Row 7Byte 56Byte 57Byte 58Byte 59Byte 60Byte 61Byte 62Byte 63

Our next task is to separate this data into swing buffers. Since the odd and even nozzles on the printhead are physically separated, we must extract the appropriate rows of pixels to give to the printer. Two swing buffers are created for each column of bytes. The first is the odd swing buffer, and the second is the even swing buffer. These correspond to which pins will be printing the data. Thus, the odd swing buffer for the first column in the above example would look like this: (Note added: from inspection of the pbm2ppa and pnm2mma code, this seems to be the even swing buffer, not the odd one (?))

Byte 0
Byte 16
Byte 32
Byte 48

And the even swing buffer looks like this: (Note added: this seems to be the odd swing buffer (?))

Byte 8
Byte 24
Byte 40
Byte 56

Ordering the swing buffers

Now we have odd and even swing buffers for each of the columns in the print sweep. The next thing for us to do is order these swing buffers and send them to the printer.

From experimentation, I have determined the ordering for the black data on the 820Cse.

  1. First, the odd swing buffers for the left 12 columns are sent as sweep data.
  2. Next, the odd swing buffer for the 13th column is sent, followed by the even swing buffer for the first column. This alternates until we run out of odd swing buffers.
  3. Finally, the even swing buffers for the last 12 columns are sent.

From experimentation, it seems that the values of the first and last 12 columns of data MUST be all 0's. Otherwise, strange results occur, including the repetition of a single swing buffer across the whole sweep.

Here is a quick reference for the ordering of the swing buffer data, assuming X columns of data.

Odd swing buffer for column 0
Odd swing buffer for column 1
...
Odd swing buffer for column 11
Odd swing buffer for column 12
Even swing buffer for column 0
Odd swing buffer for column 13
Even swing buffer for column 1
...
Odd swing buffer for column X-1
Even swing buffer for column X-13
Even swing buffer for column X-12
Even swing buffer for column X-11
...
Even swing buffer for column X-1

For different printers and color printing, the number of columns to send before we start interleaving seems to vary.
