Sorry, I should have been more specific about the problem I was fixing, which
involved getting the following error messages from ptal-mlcd:

lookupChannel(port=0,psid=4,ssid=4): invalid!
sendError(port=0,MLC): error=0x07.
reverseDataReceived(pBdr=0x08068DC0): null TCD!
exClose(reason=0x3007)

I still need to look into those "system errors".

First run "cvs update" from the top-level hpoj directory to ensure you have
the latest code and documentation, and rebuild if necessary.  SCAN-HOWTO
should cover what you need to know for scanning.  In your case, you'll want
to follow the "ptal-hp" section at the end, rather than the SANE section at
the beginning.

When you say "program", are you referring to various application programs
you're trying to print from?  lpr is the command used to print something
from the shell command line, and some applications force you to compose
your own lpr line in their "print" dialog box.  The queue name (lpr "-P"
switch) is up to you, and the default printer (if no "-P<queue>" is
specified) is normally the first entry in /etc/printcap.  (I realize this
isn't very intuitive.)
