When a job is sent from the PC, the job will be loaded into the printer and shown on the LCD screen. If this does not happen, the printer did not receive the job or did not receive a job properly. The problem is likely to lie in the computer communication to the printer.
Turn off the printer.
Make sure the USB cable is securely plugged into both the computer and printer.
Then power the printer back on.
Make sure that the USB cable is shielded and no longer than 10 feet (3 meters).
Make sure the USB cable is directly connected to the computer without passing through other devices, such as a USB hub. In AnaRIP, go to view printers and press Refresh and verify the printer connection does not say *not found*.
