Which print driver did you install. On the Cannon web site, I put in win 7 driver for ip4000, but got a blank page. If there is non, the vista ones normally will work. Is this for 32 bit or 64 bit?
Cannon is NOT the best at updating their drivers - They are tring to Capitalize on win 7 and FORCE updating equipment. More provide, just scre&*^%** the customer. I had a perfectly good cannon Lite35 scanner, which cannon would not update their driver, a work-around was to use the driver for the lide60 - Which would work so the lide35 driver could have been published with LITTLE effort.
