One thing which has always caused a problem for me with this package is
that as installed it fails to find printers and I found the issue was
in mdns.py and slp.py.

Both these files contain a line:

s.setsockopt(socket.SOL_IP, socket.IP_MULTICAST_IF,
socket.inet_aton(intf) + socket.inet_aton('0.0.0.0'))

which causes problems. Replacing the line with:

s.setsockopt(socket.SOL_IP, socket.IP_MULTICAST_IF,
socket.inet_aton(intf))

fixes the problem. I have never bothered to report this - I just
manually patch the files in /usr/pkg/share/hplip/base. Maybe see if
anyone else sees/reports this problem...

Cheers.
Dave
