Printer appears not recognized between reboots
The bug is rock solid reproducible and has been around for about 7-10 days.
With a cold boot and nothing in the CUPS print queues; (lp1 double sided A4, lp2 single sided A4) when I "print" a document it gets no further than the print queue. and there is no /dev/lp0. same if I do a test print from within CUPS is queued. Restarting the spooler from inside the CUPS GUI had no effect.
If I then reboot the m/c. I can now see /dev/lp0 (parallel port) is now present,
crw-rw---- 1 root lp 6, 0 2010-02-01 14:21 /dev/lp0,
the documents in the queue from before the reboot are now printed,
and I am able to print any further documents until the next reboot.

My work round is to “print” a file with printer off before shutdown, a waste of paper but a temporary fix.
Found following error messages: in /var/log/cup/ [I was trying to print something off the web, it locked I killed it with SIG9].
E [26/Jan/2010:12:07:16 +0000] PID 3821 (/usr/lib/cups/filter/pstops) crashed on signal 9!

Any suggestions as to what I should check or how to fix please.
