[cups] Configuration of Client-Side Avahi browsing

[Helge Blischke]

Alex,

the SNMP backend, when run from cupsd, queries the DNS for records
describing printers in the net, and these records are supplied by avahi (or bonjour
an Mac OS X).
I’d suggest you delete any DeviceURI directives from your /etc/cups/snmp.conf file,
as there is no default value and thus the snap backend won’t get any device uri matches
which are needed to add the printers found.
So, I think, you needn’t touch avahi.
