Do you want to buy a thirdparty component or re-invent the wheel?

I have found a ready to use parallel port component here:
http://www.zealsoft.com/ntport/download.html

Install the exe and you can then add the component to your project IDE. Its an easy to use component.

To read from the port:

NTPORT1.address = 888 'address for data lines
NTPORT1.bitsize = 8 'One byte
myVal = NTPORT1.value 'Read from the lines, input in decimal

And to output data:

NTPORT1.address = 888 'address for data lines
NTPORT1.bitsize = 8 'One byte
NTPORT1.value = 1 'activate D0 line..output in decimal
