To clarify A) It is an epson printer. With a centronics parallel interface B) I have a usb to centronics cable wich works ( under windows 10) C) The cable interface uses a ch341a chip. D) i dont have an ethernet (wired) connection yet with the laptop. E) DosUsb gives Errors when talking tot the printer. My thoughts were to build a driver to talk to the ch341a in c or assembly. To be continued Regards Nico
