Printing the content of div or panel

In general, we required to print the content of a portion of page. We don't need that whole page will get printed. So here I am going to provide a small java script function that can solve this problem.
Here is the code for print a specific area.

function PrintDiv() {    
var prtContent = document.getElementById('<%=divPrintArea.ClientID%>');   
var WinPrint = window.open('', '', 'left=0,top=0,width=900,height=600,

toolbar=1,scrollbars=1,status=0');    
WinPrint.document.write(prtContent.innerHTML);    
WinPrint.document.close();   
WinPrint.focus();   
WinPrint.print();   
WinPrint.close();    
}
