Windows 95, Windows 98, Windows 98SE, Windows ME, Windows NT4, Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows Vista x64

There are 3 separate directories in this zip file, one for Windows 2000 (XP, etc), and one for NT and a Win 95 directory as well.

According to the readme, this driver covers:

HP Designjet 100

HP Designjet 500

HP Designjet 800

HP Designjet 5000

HP Designjet 5500

But I've only used it for the 500.

I wasn't able to find this on the HP website, because the version of the Deskjet on that website is only monochrome... Anyway, PDFs on the website and the README has installation instructions.
