In theory, everything should be setup out of the box on supported
distros like Fedora.

That's odd. Printing with Fedora got tested quite thoroughly for the
SELinux policy changes and I've never seen this problem before. Thanks
for reporting it.

I have just committed some improvements and posted some new beta builds,
does that help?
If not, please include the client's output with "--debug printing".

Cheers
