title: Detecting browser print event
body: <p>Is it possible to detect when a user is printing something from their browser?</p>
  
  <p>To complicate matters, if we are presenting a user with a PDF document in a new window is it possible to detect the printing of that document ( assuming the user prints it from the browser window)?</p>
  
  <p>The closest I've been able to find is if we implement custom print functionality (something like <A HREF="http://stackoverflow.com/questions/1096862/print-directly-from-browser-without-print-popup-window">this</A>) and track when that is invoked </p>
  
  <p>I'm primarily interested in a solution that works for internet explorer (6 or later)</p>
