I have a really nice HP printer that's currently connected via USB

Is there a way for Fedora to use it via Avahi, rather than ipp and
giving the printer a fixed IP address?
http://localhost:631/
CUPS does find network-printers via avahi
Ensure that your Fedora client system's firewall has port 5353/udp
(mDNS) and 631/udp (IPP client) open, and things should generally Just
Work(tm).
It seems to be more than 5353 and 631. With the iptables service
running, I don't see the printer in CUPS. If I stop the iptables
service, I do. What's missing here?

HP often uses "jetdirect" (TCP port 9100), so make sure that's
permitted in your firewall as well.
With the firewall disabled, avahi-discover -a shows the printer. With it
enabled, it doesn't.
When you see it, does it show up as "JetDirect" or IPP? Did you open
TCP port 9100 in your firewall?
The rule would (in /etc/sysconfig/iptables) would look like:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9100 -j ACCEPT
and "iptables -L" would look like:
ACCEPT tcp -- anywhere anywhere state NEW
tcp dpt:jetdirect
