Printer Port I/O Controller Board and Software Device Driver

This product was developed to provide general I/O control via a printer port. The driver was developed to allow a programmer to write whatever control software desired, with an easy interface to the hardware. The device driver is embedded in a DLL and loads itself on initialization. A C++ Library is also available for direct linking. Example programs like the one above are available in MS Visual C++, MS Visual Basic and Borland Delphi.
