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.
