HP Photosmart scanner/printer:
But as it was the last one they had, they had to pack it up, even after 10 minutes searching it turns out they used the wrong box!
I hate it when the shop packs a device in the wrong box resulting in you installing the wrong drivers and you think its because its warning about Windows7 its the problem
You install Vista and it still fails
then you see you have have drivers for the a-m version of the device, but you actually have the n-z version
Windows7 detected that it was a n-z version but as it could not find drivers in windows update I had to use the setup disk.
Re-installed Windows 7 used the correct drivers downloaded from the site and everything is working now
(yes I was doing this on a spare machine I need to scan a lot of pages in a short while)
