HP Color LaserJet 2840
I have used this printer for many years and it has been wonderful! I recently remodeled and moved it to a different location. I tried to hook it back up with a network cable, rather than USB, in hopes we could print to it from our laptops. I searched forums and removed the device and reinstalled it, in hopes to get it to work with the network cable. It did not. I then read that the HP CLJ 2840 cannot be networked with Windows 7 64 bit OS. (Is this correct?)

ANSWER : I have never seen a 600N go bad. The 610 and 615 were notorious for having problems, but the 600 used the old solder that didn’t crack. What happens if you reinstall the old card and print a config page? Just want to know if it will have an ip address.
