ok, thats probably via the CUPS Browsing protocol,
https://www.cups.org/documentation.php/doc-1.4/spec-browsing.html

ouch.   CUPS printers are announced with UDP broadcasts.   thats no fun 
to filter, since the one packet is sent to ALL stations at the same 
time.   you could filter it at the client, but not at the server.   its 
udp port 631 by default.
