cups seems to have quit

[Jim Patterson <jim_patterson@xxxxxxxxxxx>]

I have two systems running FC3 and one of the systems just quit printing 
to a direct jet printer.  I have another computer with the same version 
and same setting and it prints fine.  But whenever I try to print for 
Computer B, the print job just stays in the queue.  I've tried 
restarting cups and restarting the computer but the jobs stay in the 
queue.  Ran through and canceled all the jobs and restarted cups and 
then tried to print but no glory.  Meanwhile the other Computer A seems 
to work fine and I can't figure out what happened to Computer B

If you have any ideas I'd appreciate them.  If you have any information 
on how to trouble shoot a problem like this I'd appreciate that also.  
I'm sure this will not be last time I'll be confronted with this problem.
