title: Parallel Port Output On Windows XP using Qt4 and C++
body: <p>I have a hardware device which is controlled via a parallel port connection to a PC running Windows XP. I am coding in Qt4 and C++ (Qt Creator) and need a way to output to the device over the parallel port. All information I have found so far references companies and websites that closed down 5 or so years ago.</p>
  
  <p>Does anyone have any suggestions or example code on how I can accomplish this?</p>
