I have an HP 2055DN that was working fine until a reboot today. It had started acting strange, which precipitated the reboot.
After the reboot, no network activity was taking place. After minor troubleshooting to eliminate cabling, I looked at the network config. I can now only see DHCP, Manual, and IPV6 as configuration options under the Network Config menu.
I have an identical printer in back. checked it, and sure enough the IP BYTE's, GW BYTES', SM BYTE's, are all there and configured. Replace this printer with "bad" printer and after changing the IP, it works fine as expected.
So, somehow, the printer lost it's IPV4 menu options. I reset back to factory, and no changes under the Network Config Menu.
Any ideas before I make this a USB printer for the rest of it's life?
