title: print a pdf via javascript
body: <p>I have a HTML page that has a link to a PDF. This PDF opens in a new window.
  The parent HTML page has a File->Print menu item. When the user clicks Print I want to be able to automatically open the PDF and print it. The printing part is where I am stuck. </p>
  
  <p>Any help would be much appreciated.</p>
  
  <p>Thanks.</p>
