I faced a similar problem, I have to manually enable printing again on 
my printer, sometimes more than once a day... In my case I usually find 
in the web-admin interface a message explaining the problem:
Something like "Cannot open /dev/usb/lpt0" or "Server timeout" or...

I wish cups would retry instead of failing... Anyone knows a better way 
to solve these stopping problems? I am planning to put a cronjob that 
does "/usr/bin/enable printerName" periodically just to try to 
"automagically" solve some problems....

My users are actually finding more problems with this setup that they 
were when I was printing to a win98 machine... When the printer stalledm 
they would just reboot the win98 and it would recover... Cups does not 
recover from a failure state unless manually started :-(
