To automatically print a web page as soon as it has loaded, add this script.
<html>
<head>
</head>
<body>
<script type="text/javascript">
$(document).ready(function()
{
$(window).load(function()
{
window.print();
});
});
</script>
</body>
</html>
Alternatively you could add a Print button and call window.print() from the click handler.
