During my troubleshooting, I have also tried changing the permission of printers.conf and cupsd.conf to 777 with the same result. permission 640 (above) is the default from fedora install.

The printer (Minolta PagePro 1350W) worked fine upon installation (on parallel:/dev/lp0), but I can't seem to get it to go through beh.

I have checked that my perl path is indeed in /usr/bin/perl. I dont see "network beh" in lpinfo -v, and when I try to put beh in printers.conf, I get some Access Denied errors for printers.conf in the error log. Any ideas?

One more issues I found recently with Fedora distros (FC 4 and higher):
If your configure printers using the gnome printer administration and configuration
utility, you will end up with a modified CUPS system talking to a dbus daemon and
having a daemon named eggcups running which both do a lot of hardly
documented things.

Safest on these systems is to compile CUPS from the sources, next best solution
is to install the RPMs but configure CUPS using only lpadmin and/or CUPS' own web
interface.
