[jQuery] $().ready targetting a IFRAME pdf document


HI *,
is there a way to know when a pdf embedded document is loaded?
I've tried the following solution with no successfully results
<iframe id="stampa" src="/foo.pdf">
</iframe>
<script language="javascript" type="text/javascript">
var stampa = document.getElementById('stampa');
$(stampa.contentDocument).ready(function(){
console.log("foo");
stampa.contentWindow.print();
});
</script>
