I believe it's implementing DNS-SD for network printer auto-discovery. I'm not terribly familiar with DNS-SD, but given that normal DNS is UDP based it would be unsurprising for DNS-SD to also use UDP.

DNS is actually UDP/TCP. It’s probably required for receiving unicast messages, if it’s using DNS-SD
