I don't understand this man entry.
Where exactly are you meant to put the command "UseNetworkDefault yes"?
I take it from the title that it is meant to go in /etc/cups/cupsd.conf .
But on the client or the server?
And where in cupsd.conf ?
I thought the only information needed on the client 
was in /etc/cups/printers.conf ?

Ps CUPS documentation is very, very bad.
