I have an HPOfficeJet 7610. I do NOT have a wireless connection, the printer is connected to a dataport using an ethernet cable. I was assigned an IP address by our IT staff to use with the printer. I have tried to enter it into the printer multiple times (under manual network configuration) and it will not save. The computer won't find the printer without the IP address. I cannot use wireless, I cannot use any IP address other than the assigned IP address for security reasons. The printer is intended to be networked so that multiple people in my office can use it. Please assist.
