We have a CentOS 4.x server at a hosting facility that currently has 73 
printers defined on various protocols (socket, ipp, lpd) which can see 
extensive delays in print jobs.  We are seeing the same error in our 
logs.  As a work around for this issue you can do a cupsdisable then a 
cupsenable for the effected printer which should clear the delay and 
start it working again, provided that you can ping the printer and the 
printer itself is not causing the problem. If that does not fix it try 
doing a service cups restart.
