lsb_release -rd
Description: Ubuntu 12.04.1 LTS
Release: 12.04
---------------------------------
avahi-daemon 0.6.30-5ubuntu2
cups 1.5.3-0ubuntu6
--------------------------------

Avahi for default publishes services also in IPv6 as in /etc/avahi/avahi-daemon.conf there is
use-ipv6=yes

At the same time services are listening on IPv4 addresses only.

Cups is able to discover published printers via dnssd protocol but its ipp backend prints only on the IPv6 resolved address which does not answer and it does not try the IPv4 address.

------------------------------------
Excerpt from "avahi-browse -a -t -r" to show the IPv6 and IPv4 addresses
