Listen to LPT Port

I need a piece of code that will allow me to view the data on a LPT port. What I want is 1 form and a richtextbox. All the appilcation has to do is sit there and listen to the port. When I send a document to print I want to see the data it sends to the printer and what the printer sends back. I have looked on the web for examples of source code and can only find out about data send/recieve from the com ports. Any help will be very much helpfull. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased.
