Possibly not the ideal solution but did you test whether using
avahi-daemon.conf's "deny-interfaces=" with a single interface name that
it is safe to ignore (a throw-away dummy interface) would work?

I ask because the man-page for avahi-daemon.conf seems to imply that the
interface default action is to ignore 'lo' and any point-to-point
interfaces, but if using "deny-interfaces=" without any
"allow-interfaces=" it will use all interfaces not specified - which
implies that it would then use 'lo'. E.g:

# allow-interfaces=
deny-interfaces=dummy0
# implication is that 'lo' will be used

If the functionality is only required for the localhost's CUPS service
this might be sufficient.
