code in attached file:

[for some reason it does not seem to work in Opera, although Opera does support window.print()]

<html>
 <head>
  <title> self-printing web page </title>
 </head>
 <body>
  self-printing page
  <div id="noprint" style="color: red; font-weight: bold; visibility: hidden;"> <h3>automatic printing is not supported by your browser</h3> </div>
  <script type="text/javascript">
<!--
	if(window.print)window.print();
	else document.getElementById('noprint').style.visibility = "visible";
//-->
</script>
 </body>
</html>
