Creating a virtual parallel for Windows 7 using C++
问题 I am developing an application which would redirect i/o from parallel port of, say, device A to the parallel port of device B . The two devices are connected on ethernet (LAN, WAN, internet, etc.). Device A has a physical parallel port attached to it but device B is a machine with no parallel port on it. This is what makes me emulate a parallel port on device B such that windows thinks that it has a parallel port and works in the very manner with it as it works with parallel ports on hardware
