Linux +(Special Installation with Hp820 and paper size A4) +___________________________________________________ + + +0. Introduction + +This text describes how to use the package pbm2ppa written by Tim Norman +with the S.u.S.E Linux System. This program allows the use of GDI (Winows +only) printers with Linux. The program pbm2ppa is actually a converter +between the two formats pbm (an output format from ghostscript) and the +format understood by the HP printers 720, 820 and 1000. So anyway we have to +use ghostscript to produce pbm (or faster: pbmraw) files. To print ascii +files there is an extra step invoking enscript to convert the ascii to +postscript files. I rather constructed two new printer spoolers in printcap +from scratch then using apsfilter: one for postscript files and another for +ascii files. I welcome solutions in combination with the apsfilter script. +The installation is quiet easy - after seven steps you should be ready to +print postscript and ascii files, but it may take some time to adjust the +constants properly, don't despair. + +0.1. Modifications + +This was modified on October 18, 1998 by Tim Norman to conform to the new +A4 paper support in version 0.8.5. + + +1. Installation of program package ppa-0.8.5 + +Get the packate at http://www.rpi.edu/~normat/technical/ppa/ and compile it +with + +# make 820 + +or put in your printer number (720, 820 or 1000) (see also INSTALL and README +file). + + +2. To adjust the paper size to DIN A4, use the -s a4 option to pbm2ppa or +change your pbm2ppa.conf file to read "papersize a4" (see step 5). + + +3. You can now calibrate the printer with + +For US size paper: +# pbmtpg | pbm2ppa > /dev/lp1 ( as root ) +For A4 size paper: +# pbmtpg -a4 | pbm2ppa -s a4 > /dev/lp1 ( as root ) + +or you try first printing some sample files and calibrate in step 5. + + +4. Now you can print (postscript) files with a shell script like this: + +Contents of print: + +cat $1 | gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ +pbm2ppa - - >/dev/lp1 + +After changing the file modes (i.e. chmod 755 print) you are able to print +a postscript file invoking the shell script print like: + +# print filename.ps + + +To print ascii files just extend the script print with the use of enscript: + +Contents of printascii: + +enscript -2rj -p- $1 | \ +gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ +pbm2ppa - - >/dev/lp1 + + +Check the manpage for enscript to adjust the options to your flavour. +Now you can also print ascii files with + +# printascii filename.ascii + + +5. It may be possible that you have to recalibrate your printer (see 3.) + +Here follow the results from my calibration after printing ascii files with the +shell script printascii (see 4.). The program pbm2ppa takes the arguments in the +following order: + +1. shell arguments +2. config file /etc/pbm2ppa.conf +3. Compiled options from default.h + +So whenever you invoke pbm2ppa without arguments the program uses the options +stored in the file /etc/pbm2ppa.conf, so I suggest to leave there a copy of +this file. + +# Sample configuration file for the HP820 and DIN A4 paper size +# +# This file will be automatically read upon startup if it's placed in +# /etc/pbm2ppa.conf +# + +version 820 + +papersize a4 + +xoff 0 # \ Adjust these for your printer. +yoff -600 # / (see CALIBRATE) + +# 1/4 inch margins all around (at 600 DPI) +top 50 +bottom 50 +left 50 +right 50 + + +6. To integrate the converter into the Linux system we create two printer +spooler in /etc/printcap. One to print postscript files and another to print +plain ascii files. + +Contents of /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: + + +Here follow some explanations (for more information consult the printcap +manpage). We use the lp1 device, have two spool directories +/var/spool/lpd/ascii and /var/spool/lpd/lp (better you create them now) a log +file (lf) an accounting file (af), suppress form feeds (sf), suppress printing +of burst page header (sh) and the maximum file size is unlimited (mx#0). To +integrate the converter pbm2ppa into the system we use two input filters. Maybe +you have a better solution in combination with apsfilter but until then try +this way. Actually, the two input filter files are almost identical with the +shell scripts print and printascii we created in step 4. + +File /usr/local/bin/ascii.if: + +#! /bin/sh +enscript -2rj -p- | \ +gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ +/usr/local/bin/pbm2ppa - - + + +File /usr/local/bin/ps.if: + +#! /bin/sh +gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \ +/usr/local/bin/pbm2ppa - - + + +7. Place pbm2ppa in the directory /usr/local/bin. Now you are ready to print +files with + +# lpr filename.ps + +and + +# lpr -P ascii filename.ascii + +like you are used to it. + +Enjoy + + +19.
