print.js

function printcontent() { 
	var disp_setting="toolbar=yes,location=no,directories=yes,menubar=yes,"; 
	disp_setting+="scrollbars=yes,width=300, height=350, left=50, top=25"; 
	var content_vlue = document.getElementById("content").innerHTML; 
	var w = window.open("","", disp_setting);
	w.document.write(content_vlue); //only part of the page to print, using jquery
	w.document.close(); //this seems to be the thing doing the trick
	w.focus();
	w.print();
	w.close();
}
