Re: Hardware Interface

For all,
just remember that working with parallel port on NT system (Win2k, WinxP, ...) is not simple as with previous Windows version, this bcz you've to work on a Kernel level (Ring 0), then don't use program for Windows version like Win98 or WinME on WinXP, if you do that a protection error will be popped up, to drive this port you can use some free library like one that you can found at the link:
