Error "printer cannot be contacted over the network"

Hi to all, I have newly upgraded my system to Windows 7; I have a HP DeskJet 656 that I added as a network printer. The issue I get is that the printer troubleshooter tells me 'the printer cannot be contacted over the network'. It works from a different laptop I have but not my Windows 7 laptop. I had also gone to the HP site and downloaded the Windows 7 printer update, I manually installed a new driver, I have also perform unplug and re-plug and the whole thing that I can perform, also tested the cable, it is fine . I am not sure how to fix this issue but nothing is functioning to me. Please help
