Hi I recently built a new system and have an old Hewlett Packard Deskjet 540 printer.
Went out today and bought a parallel to usb cable connector and hooked the printer up.
Made the connections and all. Turned on the PC and it recogized the cable I believe but didn't find the printer.
I know this printer has no problems on my Windows XP Professional Machine as XP came preloaded with all the drivers to make this thing work. I thought the same would be for Windows 7 but was sadly disappointed.
