I am a marble fabricator for a large tile and marble installer here in Florida. The software that we use for our CNC saw requires a Dongle to work ( a hard driver copy protection) The Laptop that my company bought me does not have a parallel port for this driver. Now i did some research online and found usb to parallel adapters, but they all say that it will only work with a printer. Does anyone know where I can get a usb to female parallel port adapter that is a true parallel port. If not, how difficult is it to install a parallel port in a laptop. Any help would be great.
