One of the most common problems beyond the regular HP maintenance repair kit installation is the failure of laser printers communication with the network.  If you HP printer, Lexmark laser or other laser printer fails to print a job then you need to check your communications.   On a network when you send a print job it goes through your switch to the laser printers Nic (network) card (HP jetdirect) and then to the laser printer copier formatter board.

The first item to check when repairing your Hp printer problem is your network cable on your printer copier to make sure its seated well in the printer and the network switch.  At the same time check to see if your NIC card (HP jetdirect card) shows a green light.  If the card does not show a green light then it is not communicating with the network or the formatter card in the printer. If this happens first install a new NIC card to repair the printer copier problem. IF the new card still does not show a light then either the formatter is bad or the network connection.

If you have a second network printer then take the network cable out  of the printer having the repair problem and put it in to the other printer to eliminate the switch and network cable as being the printer repair problem. If the cable works in the other printer then you know you will need to replace the formatter and possibly the jetdirect card.  If the connection does not work on the other printer then you have a network problem (bad cable, switch, other).  Repairing printer copiers communication problems is a process of elimination.
