Hello Doug!
If you want to print postscript jobs on your HP 690c you have to install a printer
filter which detects what
kind of data you are sending to the printer (eg. postscript, plain text, etc...)
When you try to print postscript with [lpr xxx.ps] make sure that the first line of
the postscript-file
contains : %!PS.
Make sure you have the following write/exec permissions for the filter:
-r-xr-xr-x 1 root wheel - 946 Aug 12 11:08 if-deskjet
and the Alladin Ghostscript package installed!
Script and printcap file:
First create in /etc/printcap the following line:
deskjet|lp|HP Deskjet 694-C bubblejet printer:\
:sh:sd=/var/spool/lpd/deskjet:lp=/dev/lpt0:mx#0:\
:if=/usr/local/libexec/if-deskjet:
* It tells FreeBSD that you have a printer connected to /dev/lpt0
(LPT1).
* Your spool-directory is /var/spool/lpd/deskjet (CREATE IT!!!)
* Because postscript jobs are sometimes of a very *LARGE*,size (For
example if you print a picture with xv), I have set the mx-field to 0.
(No size limits when printing a job).
* The filter is in /usr/local/libexec/if-deskjet (CREATE IT!!!)
Filter: if-deskjet
