A user states that a networked printer is not working today, but yesterday the printer worked fine. The technician checks the user's print queue and sees several jobs in the queue. The queue is…

WEP is a deprecated wireless encryption protocol; disabling it would reduce security and is unrelated to a printer that was working the previous day.

A faulty fuser would cause mechanical print defects or paper jams and would not produce the symptom of jobs failing after the queue is cleared.

Networked printers should be configured with a static IP address so that computers can reliably locate them on the network. If the printer's lease expired and it received a new DHCP address overnight, the print port configuration on the workstation still points to the old IP, causing all jobs to fail silently or with a connection error. Verifying and assigning a static IP - or reserving one via DHCP - ensures the printer remains reachable at a consistent address.

Buffer overload was effectively ruled out when the queue was flushed and restarted, yet the problem persisted.
