Network printer discovery is not currently working. I have used

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.
