Found it rather easily I think
Try this:
load the original CD in the CD/DVD drive or download from the HP site
make sure the printer is connected to the usb port and has microsoft usb drivers installed you will know if this setup because when you go to the device mgr the imaging section (scanner) will say HP OJ6600(USB) and below in the usb section of device mgr you will see "usb composite device"
open the HP printer files location. the location is :\pathtodrivers\OJ6600
scroll through the files unil you come to windows installer package file named "OJ6600x64"
right click and select "troubleshoot compatibility" you will see the screen pop up and say "skip version check"
on that same screen click "test settings"
your software will begin loading
select "keep these settings" and ignore the compatibility warning
configure and test your printer
enjoy dont worry about the popup that says "configure your IP address" it will not stop you from printing from the usb if you have wireless go ahead and set that up and you will be able to see it when you want to add a network printer.
hope this helps
