Thanks! Good info. After opening port 5353 udp it seems to be working fine.
I could have setup manually, but wasn't sure what the URI should be.

if you want _discovery_ to work, open the discovery ports in your firewall for your LAN
https://www.cups.org/doc/firewalls.html
since you appear to be using ipp/tcp, that'd be
631 (IPP/IPPS)
for cups browsing.
do NOT open access to _external_ networks.
generally useful read here:
https://en.opensuse.org/SDB:CUPS_and_SANE_Firewall_settings
if you just want to _access_ your printer at a known/fixed IP, set it up manually
