title: could we able to listen browsers pdf viewer print action via callback in JS
body: <p>I am loading a pdf content in chrome browser. Just forming  tag with appropriate src, and gets loaded with PDF container in the browser.</p>
  
  <p>And now, I need to attach JS event for print/download click action inside the pdf viewer.</p>
  
  <p>Looked into this post. <a href="https://stackoverflow.com/a/11060206/5730167">https://stackoverflow.com/a/11060206/5730167</a>
  This is listening only the parent window's print action. On printing the pdf content(which is in embed tag), the event is not captured at this point.</p>
