network printer discovery

[Neal Becker]

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.

What could I do to troubleshoot this?

Thanks,
Neal
