How the #$%&^* can I filter lpr/lpd output on SCO OS5?
Michael Sweeden
Saturday. I have set up lpr/lpd printing to several print servers on the
network, and would like to to a couple of simple things to the output in
some instances, like insert a trailing formfeed, and CR-CRNL mapping. I
found you can supposedly add an "of=filtername" to the /etc/printcap to
use a filter, so I tried creating one (though I can find nothing in the
documentation on creating one to do these things), and the filter does
not appear to be executed. A TA on the SCO support site says that the
"of=filtername" indeed does not work, that it has been reported to SCO
engineering, and that there is no current workaround. What a bummer!
I wanted to see in anybody has been in this situation and found a
creative solution to the problem. One idea I thought of overnight is
that I could create a printer connected to /dev/null that formats the
output as needed and then spools the job to the lpr/lpd printer. Anybody
have any other ideas? And, a simpler way to do crnl mapping than the one
I found: sed -e "s/$/`echo \"\015\"`/g" < source > destination?
Thanks!

There was some recent mention of a fix, but the idea of sending
through a virtual printer works well and is (IMHO) much more
flexible.
