Installed the original XP scanner software
That's the secret I believe but I've also used compatibility mode set
to XP with SP2 and installed the software using Run as Administrator.
What's behind it is that WIA in VISTA has changed and won't recognize
older methods of communicating between scanner and PC.
But installing the HP software does communicate OK but I think you may
find that specific VISTA utilities like Fax and Scan may not work.
My HPSJ5P scanner which goes back to WIN95 days and is scsi connected
works fine using the HP Copy Utility and using Deskscan 2.9.
When installing the software do not have the scanner plugged into the
PC, especially if it is USB connected, since VISTA will get into a
fight with Add new hardware trying to work at the same time as the HP
installer. Connect the USB cable when told by the HP software or after
you get to [Finish].
