I have a question regarding auto printing a pdf inside a iframe
Can it be done?

My code/html looks like this at the moment. But i havenīt got at print to test it at the moment

HTML Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Print af opgaver | Cirkus Summarum DR Big Bandet &amp; Muskelsvind Fonden</title>

<style type="text/css">

* {
	margin:0; 
	padding:0;
}

html, body {
	height:100%;
	width:100%;
	overflow:hidden;
	background:#fff;
}

</style>

<script>

function printPDF() {
	frame = document.getElementById("printpdf");
	framedoc = frame.contentWindow;
	framedoc.focus();
	framedoc.print();
}

function executePrint() {
   setTimeout( printPDF, 2000 )
}

window.onload = executePrint;

</script>

</head>

<body>

<div style="width:100%; height:100%;">
 <iframe id="printpdf" src="/images/cirkussummarum/pdf/Cirkusopgaver.pdf" frameborder="0" width="100%" height="100%"></iframe>
</div>

</body>
</html>
