Let me clarify. DNS-SD works both ways:
1. clients can use it to discover services offered by servers;
2. servers can use it to advertise their services to clients.
With the avahi support currently in CUPS, DNS-SD is used as in (1)
above, so DNS-SD-aware printers or network print servers can be
discovered by CUPS.
CUPS queues are not advertised using DNS-SD.
Perhaps the original poster was asking about DNS-SD discovery between
CUPS servers (I didn't think of that) in which case *that* is not
expected to work currently.
It does, however, work to use CUPS to discover a network print server
that advertises its queues using DNS-SD.
