Further info from Tim Waugh:

  In Red Hat Enterprise Linux 3, 4 and 5 we ship with 'BrowseAllow
  @LOCAL' (the upstream default at the time), which causes CUPS to drop
  UDP Browse packets from source IP addresses not matching a local subnet
  (i.e. interface address & netmask, for each interface).

  In Fedora we ship with 'BrowseAll All' in the CUPS configuration,
  which allows all UDP Browse packets in.

Communication to 631/udp is allowed by default in iptables configuration.
