Print PDF in a Popup with Javascript

Question

I would like to print a PDF in an Popup window in Firefox 30 with Javascript.

When I looked at on firebug, I received this message " " ”

Is there a workaround ?

Here my simple code :

var myWin = open("my-pdf.pdf");
frames["myWin"].focus();
frames["myWin"].print();

I encountered this bug; Updating compatability.js and this started working for me.
