How to Read and Write on Parallel Port using C in Windows XP

Hello,

I want to create a small project which will display scrolling text on
LED that will be attached to Parallel port. I want to create this
project in C language(possibly in Mingw) on Windows XP. I want to know
how can i access(read and write data) on parallel port in XP.

I have a program that do the same thing but in its documentation it
says that it will not work on Windows XP.

I want to create a GUI for this project in which we can enter the
desired Text to display on LED and Scrolling Speed.

Is it possible to create this Project in C?

Please Help me how can i create this project.

You will need a device driver. You can probably find a free one, and
other useful tips, here:
