My department has a static ip address in Dwinelle Hall, and
our router
forwards port 631 to the client set up as the print server
so that all our
students can print from their own laptops from whatever
network they wish
to use. The print serving client connects to the printer via
JetDirect,
and the other clients all access the printer via IPP, but
use the
network's static ip address, not the 192.n.n.n address of
the print server
so that it's easier to change the print serving client when
necessary.
Fedora Core 4 on all local clients.
>From time to time, but lately more often, the print
queue ceases to
progress. I normally solve this problem by ssh'ing to the
print server,
stopping the cups daemon, deleting everything in
/var/spool/cups, then
restarting the cups daemon. My first question is what can I
do to prevent
the print queue from getting "stuck" so often?
More seriously, the print
queue has started getting stuck every few days instead of
months, and the
last time clearing /var/spool/cups and restarting the print
daemon didn't
work; I had to physically sit down at the print server and
remove and
reinstall the printer via the control panel gui. Any
suggestions as to how
to diagnose why the print queue gets stuck and sometimes so
stuck that
clearing it and restarting cups doesn't fix it?
We had this exact same course of events happen with our
first print
serving client, which I solved by configuring a new client
to service
printing. Now that the same problem is happening on a second
print server,
I'm concerned that I won't be able to keep solving the
problem by moving
print service to a different client. Better to get to the
root of the
problem, and I would appreciate any suggestions to make our
configuration
more robust. Through all these problems, I've always been
able to telnet
to the printer from all of the clients on the same router as
the printer.
