If I stop firewall (systemctl stop iptables) I can communicate with the printer.  If I restart the firewall I get "unable to locate printer".
My printer is 
dnssd://Brother%20HL-L2395DW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-3c2af4436b47

Any ideas?

Network printer discovery is not currently working.  I have used this printer before from this fedora laptop, but now cups can't communicate with it, and if I try to add printer, no network  printers are discovered.  I can get to the printer's web page from this laptop, and I can print from other devices.

I dropped the local workstation firewall (in my case, with sudo systemctl stop firewalld) to get discovery to work. After CUPS had the printer configured, I could re-start the firewall.
