I installed nmap and had a look at the printer.  It is listening to
ports 21, 80, 427 (srvlock) and 9100 (jetdirect), all TCP.  Port 9100
is not in /etc/services and I'm not sure if this is significant.  I've
added it to see what happens.

  In response to another suggestion, there is no postscript module for
this printer as it uses CAPT, the Canon printer driver.  The software
provided by Canon puts "pstocapt3" in /usr/lib/cups/filter.  I notice
that there is a report of /usr/lib/cups/filter/pstocapt3 and
/usr/lib/cups/backend/socket both being killed by a 9 signal in
/var/log/kern.log.  I wonder what this means?
