Did you look at the second page of that article? 
The one that deals with InpOut32.dll? 
Your obvious first step is to write/download a test program using it.
Read this:

Download InpOut32.dll and try using it with one of the test programs
referenced from it. If that works, you're home and dry. Just change
LCDHype and its dll to work with InpOut32.dll

I think they are very simple functions that make direct access to
parallel ports for DOS/Windows systems.

Actually, there's rather a lot available and its rather easy to find.

Here's some reading about the Linux side:

These were found with an Altavista search on "/dev/parport" and were the
top two items on the first page of search results. Google may or may not
be your friend (Altavista finds fewer useless comparison sites and
doesn't show adverts) but you should make more use of them.
