I administrate a computer lab with 6 computers and a printer. The computers are connected to the HP Laserjet CP2025 printer via TCP/IP.
Sometime during the night after I shut physical access to the lab, the printer prints several pages of what appear to be HTML headers for popular websites like the BBC and Wikimedia. This happens every evening. I have not written a script to do this on any of these computers so I don't know where it's coming from.
I am wondering how I can stop this. I'd prefer to keep the printer IP the same because I have to fill out some paperwork to reserve a new IP and I would have to re-install the printer on all the computers.
Please let me know if you need more details. I know there's a lot I'm leaving out but I don't even know what's relevant in this situation.
