pbm2ppa - convert portable bitmap (PBM) to HP's Printing Performance Architecture (PPA) file format SYNOPSIS
pbm2ppa [options] [ <infile] > [ <outfile]> ] ] DESCRIPTION
Reads portable bitmap (PBM) format as input. Outputs a stream suitable for processing by Hewlett-Packard's range of Printing Performance Architecture (PPA) printers. pnm2ppa supports the HP 710c, 712c, 720c, 722c, 820c, and 1000c series printers. (Portable bitmap (PBM) format output can be produced from PostScript(tm) input by the GhostScript driver "pbmraw".) OPTIONS
infile Input file infile is either a path to a file or device, or '-' to indicate stdin (defaults to stdin) outfile Output file outfile is either a path to a file or device, or '-' to indicate stdout (defaults to stdout) -b bottommargin Sets the bottom margin bottommargin in units of 1/600 inches (e.g., -b 150 = 0.25") -d Displays the current configuration -f configfile Overrides reading the configuration from /etc/pnm2ppa.conf, and uses configfile instead. -h Displays program usage -l leftmargin Sets the left margin leftmargin in units of 1/600 inches (e.g., -l 150 = 0.25") -r rightmargin Sets the right margin rightmargin in units of 1/600 inches (e.g., -r 150 = 0.25") -s papersize Sets the paper size. Possible values for papersize are a4 (A4), letter or us (US Letter, 8.5"x11"), and legal (US Legal, 8.5"x14"). The default is US Letter. -t topmargin Sets the top margin topmargin in units of 1/600 inches (ie -t 150 = 0.25") -v printertype Selects the printer model. Possible values of printertype are: 710, 712, 720, 722, 820 and 1000. The default is the HP DeskJet 7X0 Series (710, 712, 720, 722). -x xoffset Sets the x-offset xoffset from the left of the page. Units are 1/600 inches -y yoffset Sets the y-offset yoffset from the top of the page. Units are 1/600 inches NOTES
The configuration file is read in first. Command line arguments then modify the resulting definitions. The -x and -y options accumulate. The -v option resets all definitions back to an inbuilt default for that printer and should be used before subsequent -b -l -r, -t, -x, and -y arguments. SEE ALSO

This program was written by Tim Norman. It originally supported black and white output on the 820 series. This program is almost obsolete; its successor pnm2ppa will support color printing. BUGS
This is a stable driver, but does not support color printing. pnm2ppa(5 Feb 2000)

pbmtoppa - convert PBM image to HP Printer Performance Architecture (PPA) SYNOPSIS
pbmtoppa [pbm_file [ppa_file]] DESCRIPTION
pbmtoppa converts page images in PBM format to Hewlett Packard's PPA (Printer Performance Architecture) format, which is the data stream format expected by some HP "Windows-only" printers including the HP Deskjet 820C series, the HP DeskJet 720 series, and the HP DeskJet 1000 series. pbm_file is the file specification of the input file or - for Standard Input. The default is Standard Input. The input file contains one or more PBM images, with each one being a single page. Each image must have the exact dimensions of a page (at 600 pixels per inch in both directions). Significantly, this is the format the Ghostscript produces. ppa_file is the file specification of the output file or - for Standard Output. The default is Standard Output. To print Postscript on an HP PPA printer, just use Ghostscript with the pbmraw (or pbm) device driver. You can generate a test page for use with this program with pbmpage. You can also set up a printer filter so you can submit PBM input directly to your print queue. See the documentation for your print spooler for information on how to do that, or look in hp820install.doc for an example lpd print filter for Postscript and text files. Sometimes, pbmtoppa generates a file which the printer will not print (because pbmtoppa's input is unprintable). When this happens, all three lights blink to signal the error. This is usually because there is material outside of the printer's printable area. To make the file print, increase the margins via pbmtoppa options or a configuration file. See the CALIBRATION section below. OPTIONS
-v version printer version (720, 820, or 1000) -x xoff vertical offset adjustment in 1"/600 -y yoff horizontal offset adjustment in 1"/600 -t topmarg top margin in 1"/600 (default: 150 = 0.25") -l leftmarg left margin in 1"/600 (default: 150 = 0.25") -r rightmarg right margin in 1"/600 (default: 150 = 0.25") -b botmarg bottom margin in 1"/600 (default: 150 = 0.25") -s paper paper size: us or a4. Default is us. -f cfgfile read parameters from configuration file cfgfile The -x and -y options accumulate. The -v option resets the horizontal and vertical adjustments to an internal default. CONFIGURATION FILES
You can use configuration files to specify parameters rather than use invocation options. pbmtoppa processes the file /etc/pbmtoppa.conf, if it exists, before processing any options. It then processes each configuration file named by a -f option in order, applying the parame- ters from the configuration file as if they were invocation options used in the place of the -f option. Configuration files have the following format: #Comment key1 value1 key2 value2 [etc.] Valid keys are version, xoffset, yoffset, topmargin, leftmargin, rightmargin, bottommargin, papersize, or any non-null prefix of these words. Valid values are the same as with the corresponding invocation parameters. EXAMPLES
Print a test pattern: pbmpage | pbmppa >/dev/lp1 Print three pages: cat page1.pbm page2.pbm page3.pbm | pbmppa >/dev/lp1 Print the Postscript file gs -sDEVICE=rawpbm -q -dNOPAUSE -r600 -sOutputFile=- | pbmtoppa | lpr CALIBRATION
To be able to print successfully and properly, you need to tell pbmtoppa an X and a Y offset appropriate for your printer to use when gen- erating the page. You can specify these offsets with the -x and -y invocation options or with the xoff and yoff parameters in a pbmtoppa configuration file. To determine the correct offsets, use the pbmpage program. If while trying to do this calibration, the printer refuses to print a page, but just blinks all three lights, specify large margins (e.g. 600 pixels -- one inch) via pbmpage invocation options while doing the calibration. For example: pbmpage | pbmtoppa >/dev/lp1 or pbmpage | pbmtoppa | lpr -l (if your printer filter recognizes the '-l' (direct output) parameter). In the test pattern, the grid is marked off in pixel coordinate numbers. Unfortunately, these coordinates are probably cut off before the edge of the paper. You'll have to use a ruler to estimate the pixel coordinate of the left and top edges of the actual sheet of paper (should be within +/- 300, may be negative; there are 600 pixels per inch). Add these coordinates to the X and Y offsets by either editing the configuration file or using the -x and -y command-line parameters. When pbmtoppa is properly calibrated, the center mark should be in the center of the paper. Also, the margins should be able to be as small as 1/4 inch without causing the printer to choke with 'blinking lights syndrome'. REDHAT LINUX INSTALLATION
RedHat users may find the following tip from Panayotis Vryonis <> helpful. The same should work for the 820 and 1000, but it hasn't been tested. Also, use the pbmraw GSDriver if you have it; it's faster. Here is a tip to intergrate HP720C support in RedHat's printtool: Install pbm2ppa. Copy pbm2ppa to /usr/bin. Edit "printerdb" (in my system it is found in /usr/lib/rhs/rhs-printfilters ) and append the following lines: ----------------------Cut here----------------------- StartEntry: DeskJet720C GSDriver: pbm Description: {HP DeskJet 720C} About: { This driver supports the HP DeskJet 720C inkjet printer. It does does not support color printing. IMPORTANT! Insert "- | pbm2ppa -" in the "Extra GS Otions" field. } Resolution: {600} {600} {} EndEntry ---------------------------------------------------- Now you can add an HP720C printer just like any other, using printtool.
