HP LaserJet P2015 no longer prints over the network

"Print out a status report locally from the printer and see what IP-settings you have. Is the IP address obtained automatically by DHCP then you should be able to configure the PC to find the printer and print to that IP-address.

There may also be that the printer IP address is manually configured, which sometimes are common for printers in IP networks in order to keep the IP address. Then you can enable automatic IP address (DHCP) and see that it works.

A better method than using fixed IP-addresses (to avoid IP conflicts) is to add the printers unique MAC-address to the DHCP table in the router which will give the printer the same IP address whenever restarted."

"…both of my P2015 have gone completely insane. They stopped working like a printer at all. Random error light codes; changing error codes as time passes, etc.... I baked one of the printer’s system boards in a pre-heated oven at 400 for 7 minutes. It works perfectly now. The other was squeeling at times too, can’t wait to try it again tomorrow…

PS By system board I mean the little circuit board with 5 or so connectors/cables on the left side of the printer, remove the left plastic panel and you will see it…"

"(1) First try replacing your Ethernet cable.

(2) The Ethernet jack on the printer is not sturdy and may have been damaged by a cable pulling on it. You may be able to re-solder it.

(3) You could also make the printer available on your network by either a computer or a print-server."
