The technician should roll back the printer's firmware because the problem began after the affected printer was updated. The same users and documents print correctly on another network printer, which indicates that the workstations, documents, and general network connectivity are functioning properly. The fault therefore follows the updated printer. A defective or incompatible firmware release can affect page processing, print- language interpretation, memory management, or communication with existing drivers, causing blank output.
Restarting the printer may clear a temporary condition but will not correct incompatible firmware. Testing through USB could help isolate network connectivity, but the printer is already receiving jobs and producing pages, so basic communication is occurring. Reinstalling the driver on every workstation is unnecessary when those computers successfully print the same content elsewhere. Restoring the previous stable firmware version directly addresses the recent change.
