"With a 64 bit version of Windows 10 the HP Deskjet 722c printer will not work, even with the patch and if you bought a proper converter cable. I spent quite a bit of time on this with Windows 8 and 8.1, and managed to get a computer with an actual parallel port to eliminate the converter as an issue. No success."
Hope the information provided is useful. If the issue persists, reply here and we will be glad to help you.
