I used the same driver to install this printer on my laptop, on my wife's laptop and my son's laptop, all running Windows 7 and they have no problem. Also, every time I click on "Printer Properties" it says that the printer driver is not installed and I have to install it again; so I have installed the driver about ten times now and it always does the same. I have used the Windows 7 driver, the Windows Vista, the XP driver and the Windows Update driver and I always get the same result.
I will try a few more tricks when I get home and see what I get and post back.
Thanks for your help.
