I have FreeBSD 5.2-CURRENT.
/etc/printcap
hp2200:\
:sh:\
:rm=hp2200:\
:sd=/var/spool/output/lpd/hp2200:\
:mx#0:\
:if=/usr/local/libexec/hpif2:\
:lf=/var/log/lpd-errs:
/usr/local/libexec/hpif
#!/bin/sh
#
# hpif - Simple text input filter for lpd for HP-PCL based printers
# Installed in /usr/local/libexec/hpif
#
# Simply copies stdin to stdout. Ignores all filter arguments.
# Tells printer to treat LF as CR+LF. Ejects the page when done.
printf "\033&k2G" && cat && printf
"\033&l0H" && exit 0
exit 2
In the dfA009exampleFile in /var/spool/output/lpd/hp2200 there is the
value @PJL SET DATE=31-12-2003. I want to create a filter that will
change that value to the year 2000.
Why? If you recall HP has date information in their printer cartridges,
that after a certain date the cartridge becomes "expired". Although
you
have plenty of ink or a cartridge that has been on the shelf for along
time.
If I manually vi the file I can print, therefore I was trying to find a
filter that would send the PJL command to set the date to a default
01-12-2000 all the time.
Has someone already completed such a thing?

I would have expected that this would be where the PJL command is added. If some how it is added ahead of the filter you could edit the filter to pass the input though sed to change the date in the PJL command to whatever you want.> #!/bin/sh > # > # hpif - Simple text input filter for lpd for HP-PCL based printers > # Installed in /usr/local/libexec/hpif > # > # Simply copies stdin to stdout.

I didn't realize they did that via PJL commands. Luckily we tend to send postscript, and I don't think we've ever hit one of those expiration messages. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
