Using print button, I am printing the html page from google chrome Able to print the page but title text is not appearing in the print preview for printing we are using JavaScript

Can anyone help me how to resolve this issue?

JavaScript Code:

   var contentWindow = proxyIframe.contentWindow;
   contentWindow.document.open();
   contentWindow.document.write('<iframe src="' + url + '" onload="print();" width="1500" height="' + (height + 700) + '" frameborder="0" marginheight="0" marginwidth="0"></iframe>');
contentWindow.document.close();

Thanks in Advance!
