Hi, Rags -
I see what you mean. Most HP printer drivers are downloadable, but not this one.
I wonder if Win7 will have a built-in driver for your printer. Hit "start," and then select "devices and printers." Select "add printer" and see if Win7 will let you install that way.
The 800-series HP printers were the last really good printers HP made. I can see why you don't want to give it up.
