Comment 6 for bug 801306

Looking at https://wiki.ubuntu.com/IPv6 it seems fe80::/10 is a local-link self-assigned IPv6 address. My router doesn't do ipv6, so I guess this is Ubuntu giving itself an address. I'm using a pretty standard install of Ubuntu - fairly new in fact, and a pretty standard domestic cable modem and router, with nothing special configured, certainly no IPv6.

Whilst I could go through the process of blacklisting the ipv6 module or editing my grub.conf to disable ipv6, this seems very extreme for a normal user just to get printing working?
