print() doesn't work in IE after opening a new window. It works in Chrome. Here's a tester:
<html>
<head>
<script type="text/javascript">
function openWin()
{
myWindow=window.open('','','width=200,height=100');
myWindow.document.write("<p>This is 'myWindow'</p>");
myWindow.focus();
myWindow.print(); //DOES NOT WORK
}
</script>
</head>
<body>
<input type="button" value="Open window" onclick="openWin()" />
</body>
</html>
