Might not be relevant, but there's a gtk update this morning that said
something about fixing a printer bug:
https://www.redhat.com/archives/fedora-package-announce/2009-November/msg00551.html

If system-config-printer can get to the printer for the 'test print' then it's
unlikely to be a firewall issue (unless I misunderstood you).  You can check
selinux blocks by running 'sealert'.

You try updating gtk and restarting firefox to see if the problem magically
goes away.
