To reproduce without need of a printing client, run the command avahi-browse -a -v -t -r
in a terminal window. Then look for entries arising from CUPS queues. They report "port = [30466]". Entries from IPP printers report correctly "port = [631]" (what CUPS as an IPP-based printing system should do as well). ** Changed in: cups (Ubuntu) Status: New => Confirmed ** Changed in: cups (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/792309 Title: cups announcing wrong port numbers on avahi -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
