I wrote a c++ program to control by parallel port for my old computer but for new computer no parallel port so I have to use USB to parallel adapter and I understand that I have to use API to modify the program to work in the new computer, pls help me with example for handling this adapter
thanks a lot
Dear,
Did you try this?
I'm sure that you do not want to write a program to virtual the USB-PARALL device. If the answer is yes, please find answer from many open-sources usb to parallel.
As I see, You need to have the driver for the adapter. Install it on the new computer. Then open the device manager, you will see a virtual parallel device. Change the old LTP port to the new LTP one shown in device manager console. That's enough for your application to operate a virtual adapter.
