LPRng Printing Problem

["David Wilson" <dwilson@crim.umd.edu>]

I recently installed potato and am new to Linux.  I seem unable to print using LPRng and haven't found any helpful information in HOW-TOs, although I'm sure the info I need is there somewhere.  When I issue the "lpr file.ps" command, nothing happens, no errors, no output.

I have two parallel ports (in Windows they are LPT1 and LPT2).  My printer is connected to the second port (/dev/lp1?).

My printer is an HP720C (I know ...).  I have install pbm2ppa and can successfully run the following script to directly send a file to the printer:

#! /bin/sh
cat $1 | gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \
pbm2ppa - - >/dev/lp1

I have modified this script (as per the documentation for pbm2ppa) to use as a filter in the printcap file:

#! /bin/sh
gs -sDEVICE=pbmraw -q -dNOPAUSE -r600 -sOutputFile=- - | \
pbm2ppa - -  |

This file is saved as: /usr/local/bin/printps.filter.  My printcap file reads:

lp|hpdj720|HP Deskjet 720c:\
	:lp=/dev/lp1:sd=/var/spool/lpd/hpdj720:\
	:sh:pw#80:pl#66:px#1440:mx#0:\
	:if=/usr/local/bin/printps.filter:\
	:af=/var/log/lp-acct:lf=/var/log/lp-errs:

The following is the output from "checkpc".  Everything looks fine to my novice eyes.  Any ideas on what I'm missing?

Thanks, Dave
