title: PDF file checkbox validation for printing?
body: <p>I have a PDF document which has 2 checkboxes. I have validated them in Acrobat pro X.</p>
  
  <p>My question is how do I prevent the document from being printed without checking either one of the checkboxes ? User has to check least 1 checkbox before the document can be printed.</p>
  
  <p>I got checkbox1 and checkbox2</p>
  
  <p>How do I do this via Javascript?</p>
  
  <p>Thanks.</p>
