CUPS - printer is present, detected, idle - but doesn't print

[Karl Auer]

I am trying to get a directly-connected parallel-port printer to work
under Ubuntu (Feisty server). I want the printer to be accessible from
the local host, and to be made available to other hosts on the local
network.

I have installed CUPS on the server as far as I can tell, and lpstat
reports the printer as idle and accepting jobs. The parallel port is
detected during startup (and the connected printer is correctly
identified). When I submit a job using "lpr -P", it is accepted without
comment, but nothing is printed, and lpstat still shows the printer as
idle and accepting jobs.

The only thing that I find odd is that after restarting cupsys, I see
messages like this in /var/log/cups/error_log:

E [22/Jan/2008:17:38:55 +1100] CUPS-Accept-Jobs: Unauthorized
E [22/Jan/2008:17:43:04 +1100] CUPS-Add-Modify-Printer: Unauthorized
E [22/Jan/2008:17:43:04 +1100] CUPS-Accept-Jobs: Unauthorized

Doesn't look right, but I've no idea why they would be unauthorized. In
cupsd.conf I have "listen *:631", but I'm not sure what else I should be
looking for in there.

At no stage have I specified any kind of driver for the printer type
concerned - is that something I must do? I was assuming that I could set
it up this way as a "raw" printer and that clients would generate
properly formatted output for it.

Regards, K.
