It looks like HP have finally issued Windows 7 drivers for the G4010.
Mind you, so much for their bloody “sign up and we’ll email you when they are available” crap! I did, and they didn’t.
I’ll update this post once I have installed and tested the driver… Which I now have, and it works great! If you go to this link you can choose your version (32-bit or 64-bit). The software is the FULL VERSION – so it includes OCR. It is also better than the original Vista version.
EDIT 24/05/2010: Oops! Forgot to update it like I promised. Not a lot to say, really. The drivers work perfectly, and so does the OCR.
Summary: official drivers are available for the G4010 scanner, and have been since February. They are for both 32-bit and 64-bit Windows 7. They work perfectly, so the wait was worth it in that respect.
