According to the CUPS upstream bug report https://www.cups.org/str.php?L4305
this is an Avahi bug: ---------- This is an Avahi bug - there is no zone ID in the address, and the address is link-local (zone ID required). Just using the hostname (and praying that the distro/OS that is using Avahi has bothered to setup Avahi to do resolution of .local names) isn't going to help, all it will do is create another bug report that printing is "slow" because we'll try IPv6 and then fall back to IPv4 when the IPv6 connection times out. ---------- Moving to the avahi package. ** Package changed: cups (Ubuntu) => avahi (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1099184 Title: Avahi reports IPv6/IPv4 and "dnssd" CUPS backend only tries IPv6, no IPv4 fallback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1099184/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
