Officejet 4500 not working

[ofekfischer]

I bought an officejet 4500 none wireless version few months ago and everything worked fine. three days ago the computer stopped to show me the printer and i'v got a messege that it's no connected. i tried to reconnect it and to restart both computer and printer and it didn't help. does anyone have any idea how to solve it?

Make sure the wireless transceiver on the OfficeJet 4500 is enabled.
