I would uninstall printers software/unplug the printer from power supply and its connection to your computer.
Shut down the computer then turn it back on and plug in your printer to power supply and connection to your computer.
Windows 7 will see something new is being added and should find your printer then do a test page.
Hopefully this will work!
