If you are programming in Windows (even in a Command prompt), you can't just read or set the port.  You will need to use some higher-level functions.  The pin values equate to certain status codes available in a structure called PRINTER_INFO_2.  See

for some example code.

You never stated what you REALLY want. In my suggestion I told you already that th eexperts need feedback to their comments or else we have to suspect the comment was enough information for you. Dan offered you twice to get back to him about any help and I am sure he is still willing to help out. BUT: you have to ask him! He just doesn't know ...

I would suggest to explain any further problems here.
