Thank you for all kindly respons for my problem. But what i really looking for is a way to use usb to printer converter/cable like lpt port. I'm not going to send data to printer, but send data to printer port. So there is difference beetwen them. So i'm looking for how to map the converter to I/O address, like on old pc LPT1=378h, LPT2=278h, etc. Could it be done in delphi? Or there is something tricky with the converter ?
