RFE: Sharing specific printers only for specific network

[zdohnal]

Hi,
IMO it would be good to have option to share printer queue only in specific network - it means avahi-daemon will advertise the printer only in this specific network. I'll look into it and I'm willing to cooperate on it.

For reference, the mailing list discussion talked about using allow/deny lines to determine which network interfaces should be used for Bonjour advertisements. Alternately we could add a BrowseInterface directive to specify the interface to use (which would apply to all printers).

Enhancing allow/deny option to divide created printers into groups by interfaces sounds good. BrowseInterface directive is not compatible with idea of "specific" printer.

For a per-printer approach we would need some option in the printers.conf entry of the printer, for example "dnssd-interfaces=eth0,wlan0,lo" to advertise the printer only on eth0, wlan0, and lo but not on any other interface and a blacklist-style option like "no-dnssd-interfaces=eth1,eth2" to advertise a printer on all interfaces but eth1 and eth2.
But global (for all printers) options foir selecting the interfaces to advertise on (like BrowseInterface) in cups-browsed.conf would also be a nice feature.

The GNOME project is currently workin on a GUI to configure printer sharing and would like if CUPS had the functionality to choose interfaces to share the printer to individually per printer.

@tillkamppeter There is no support for per-printer or per-server configuration of a Bonjour/DNS-SD network interface, nor do we have plans to do so anytime soon.

We have decided this will not be added to CUPS, sorry.
