I have a laserjet IIIp (wPCL5) on lp0, it configures fine and I can print a cups test page OK. However, the gnome print manager insists that "no printer detected" and wants to start the printer configuration wizard.
I havn't tried this logged in as root, so it may
be a permission problem. However, it has been going before - I'll get to that in a bit.
On command line, if I try:
$ lpr /dev/lp0 test.txt
I get: "permission denied" ... well OK so:
# lpr /dev/lp0 test.txt
and I get: "lpr: error - scheduler not responding!"
However, if I try it this way:
$ lpr -P laserjet3p test.txt
It prints away and generally looks innocent.
Interestingly, the last printing I did was via dvips thus:
which worked fine then, but gives me

' TeX output 2005.05.08:1956' -> |lpr
lpr: error - scheduler not responding!
though it works fine with:
$ dvips -P laserjet3p mybook.dvi
I'm pretty sure this is a clue!
Now - it's been a while since I printed anything. Two major changes have occured since:
1. Network set up - with NFS shares. This computer is the server.
2. Mozilla Firefox installed
Now Firefox had the famouse "cannot print" trouble - which I was testing when I found that the print manager couldn't detect the printer queue. However, I got firefox to print by replacing the default print command with "lpr -P laserjet3p".
So - I understand why lpr /dev/lp0 gives permission denied - but why cannot the print server see the printer dammit!
