The avahi-daemon has either been removed by rm. or by chmod -x on all
machines here, yet cups shared printers (plural) can use those shared
printers just as if they were plugged into that machine. So IMO removing
or disabling avahi-daemon has nothing to do with cups sharing.
You are saying it won't work, but it does here. What else is there except
cups.
