At a fairly sizeable, well-known company that I worked for, one of the IT technicians always told us to “wiggle the wires” when a print fault was reported. While this became something of a standing joke, you know what, she was usually right; often the fault was caused by a loose connection or a cable that had inadvertently been pulled out of its socket. Otherwise check network connections and that documents are being sent to the correct print device.
