With this utility and the corresponding hardware, you are able to test the proper working of the LPT port of your computer. It is also a very handy utility during your LPT port development activities. The LPT Test Utility i386 / x64 works with Windows 95, 98, ME, SE, 2000, NT, XP, XP x64, Vista and Vista x64. In most modern computers, there are no LPT ports available anymore. You have to install a LPT PCI card. To be able to test a LPT PCI port, you have to enter the PCI base address, which can be found in Windows Device manager, of the card in the LPT X address menu.
