Well, No Windows 7 drivers available, but try the Vista drivers, they may work with Win 7. Entry level Canon printers are relatively cheap if the HP is not worthy. Google search. Try it when looking for an online product page in the future.
I have Windows 7 home edition and I installed IrfanView through which, the HP 3970 scanner works just fine.
Nobody should be without IrfanView anyway.

July 9, 2011 I tried IrfanView. It solved the problem for me. Once you download and install it, look under File. You will see the selections for the TWAIN scanner. Works just fine! Thanks!
