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.
