The only thing I see here, is if you have you have your machine running 24/7, 
or shut it down at night.

For example. You boot the machine using the udev version that was ok. then you 
do an update, and install the dodgy/defective udev. The new udev won't make 
any changes to the parallel devices being created in /dev unless you reboot.

The machine is still up and running, and 2 or 3 days later a new update for 
udev arrives, which fixes the parallel port problem in /dev.

As your machine has been running continuously you have not seen the problem 
caused by the faulty udev update. Your machine now has installed the revised 
udev package, which is again able to create devices for the parallel port, 
and therefore the printer is running oblivious to the fact that a udev update 
(the dodgy one) could have sent it out to lunch.

Just some thoughts.
