C. A job in error status is at the top of the print queue.
D. The printers IP address has changed.
E. New drivers have been released and need to be installed.

Answer: C, D

Explanation:
The possible cause of the problem in this case is that either a job in error status is at the top of the print queue or the IP address of the printer has changed. Sometimes, certain print codes in the file that is printing can confuse the print job and the job gets stuck in the print queue. The printer would not start printing again till that print job is removed from the queue. Sometime if the IP address of the printer is changed you cannot print. To find this problem you can ping the printer from your computer.
