Comment 7 for bug 1251973

Hrmmm, this
  E [20/Nov/2013:08:34:34 +0100] Unable to bind socket for address [v1.::1]:631 - Address already in use.
  E [20/Nov/2013:08:34:34 +0100] Unable to bind socket for address 127.0.0.1:631 - Address already in use.
makes me think that even though you purged the printer the socket for some reason has not been freed and is still in use. Can you purge the driver, reboot (its the easiest way to make sure you cleanup tasks that may be using the socket) and try installing again.

The message
  [ 1330.139369] type=1400 audit(1384932874.955:57): apparmor="STATUS" operation="profile_replace" parent=3595 profile="unconfined" name="/usr/sbin/cupsd" pid=3600 comm="apparmor_parser"

just means that a process that is unconfined replaced the old cupsd profile with a new one. This is expected as the instructions I provided told you to use restart which reloads/replaces profiles.
