Hi, I'm hoping someone can help me with a problem. I'm new to cups,
but I've been trying to read up and still can't figure this out.

I have a linux computer at home, and two windows laptops. I use cups
on Fedora Core 3 to handle a USB printer for local requests. I also
use cups to print from two windowsxp laptops using IPP
(http://servername:631/printers/myprinter) using the "Internet
Printer" option in Windows.

For weeks I was happily printing from my windows clients.

Then a weird thing happened. Suddenly jobs from my windows clients
stopped printing. Locally-started print jobs (from my linux computer)
will still print. Print jobs from the windows computers will still
show up in the queue as jobs, but won't actually get printed.
Windows-client print-jobs show up in access_log and error_log, but not
in page_log. The windows jobs show up as "Completed" even though they
never get printed.

I turned on debug level in the logs, but I can't see anything
obviously failing. I do notice that in the jobs that don't end up
printing, there are no reports of "Started backend ..." like there are
in the successfully-printing jobs

I guess something changed on my system to cause this, but I can't for
the life of me figure out what. I can still open up
http://servername:631/printers/myprinter in a web browser on a windows
machine and see the cups server serving web pages. I can even print a
test page from this web interface. But if I try to print normally
from any windows client I am silently stymied. No errors, just no
printing.

Any help is greatly appreciated. Even pointers in the right
direction.

thanks,
Matt
