Hi Labviewer,

your program is in one detail not correct - the address
of printerport you have to use as hex number.
Find attached a simple test-program for paraport and a
pin-list(see also the web-adress in pin-list, interesting tips available). As long as you use Win9xx,the attached testprogram should work. Play with the bits. If your platform is NT or W2k you need some
specials - if neeeded write to: werner.hasche@web.de
