Is your "network printer" an actual IPP printer or a queue being
advertised by a CUPS server? Also: is the autodiscovery being done
by cups-browsed? There is an entry in printers.conf, so I guess it
is the managing utility.

The wiki was written in the days before autodiscovery of IPP printers.
It might need some readjustment to take account of this.

Brian.
