poma and antonio, what do you get for:
rpm -qa | grep firewalld-config

And can both of you confirm which firewall-config checkbox you're
checking to resolve this? Is it ipp or ipp-client or both? I'm going
to guess it's just ipp-client that's needed.

Note that ipp and ipp-client uses port 631 which is below the open
ports 1025+ for Fedora 21. It has to be explicitly permitted and on a
clean Fedora 21 Workstation VM for me ipp and ipp-client are disabled
and thus blocked by firewalld. Thing is, it's not obvious because
firewall-config isn't installed by default.  So it's actually an
interesting question what the intended workflow for printing to
network or remote CUPS printers is supposed to be? It's a little silly
(not really in the funny way) if it's "oh yeah so, yum install
firewall-config and check ipp-client and then you can print." Umm
really?

With the IPP Everywhere work in progress, I think this has to be
enabled by default in order for its goals to be achievable.
