Logic Analyzer Project

I have a logic analyzer project and I have no problem in hardware but I have a big problem in the code which must be written in C# and the code must do the following:

the code must take a values from the parallel port of the computer (0 or 1)

and then synchronously draw lines each 1 second (take values and draw in parallel mechanism) these lines are continuous and must be high correspond to 1's and low coreesponds to 0's

I will be so thankful if you help me to solve this problem,please
