My HP 4600 works perfectly on my Win7 desktop and laptop. I don't recall doing anything special to get it running. It appears in my devices tab and I right click and select "scan" and it works.

I'll have a play tomorrow for you Gav - but it DOES work.

Microsoft finally got it right with Windows 7. I'm not a MS Fanboi, but Macs can be a real pain to do simple tasks like connecting a printer. Windows 7 still needs 234 reboots when applying updates and I've had to re install twice because of Virus issues. DON'T USE "Microsoft Security Essentials" as your Anti Virus - it is the worst AV I've ever used.
