This is pretty common, and steals a trick from the syslog files.
Here is how you set the printcap up:
logger|alias_for_stupid_programs|...
:lp=/var/run/logger/outfile
:filter=/usr/libexec/filters/neatformatter
#!/bin/sh
# neatformatter
echo "--------- JOB START -------"
echo $0 "$@"
/bin/cat
echo "--------- JOB END -------"
exit 0
Now when you print a job it goes into the /var/run/logger/outfile with
each file separated by JOB START and JOB END lines.
You must modify your 'lpd startup script' a bit to create the
directory for the outfile; make sure you have ownership correct.
The owner will either be 'daemon' or 'lp' depending on your system.
#...
start)
if [ ! -d /var/run/logger ] ; then
mkdir -p /var/run/logger
fi
chown lp /var/run/logger
And finally, the crowning touch: you can do file rollover as well.
I use the program 'newsyslog' with the following entry:
configuration file for newsyslog
# $FreeBSD: src/etc/newsyslog.conf,v 1.25.2.4 2001/02/26 09:26:11 phk Exp $
#
# logfilename [owner:group] mode count size when [ZB] [/pid_file] [sig_num]
/var/run/logger/outfile lp:lp 660 10 1000 * Z
This says 'update the /var/run/logger/outfile using owner:group lp:lp and creat
it with mode 660 perms. Keep at most 10 files, and roll over when they reach
1000 Kbytes. Compress them using Gzip.
