var sURL = document.location.href;
var WshShell = new ActiveXObject("wscript.shell");
WshShell.run("rundll32.exe c:\windows\system32\mshtml.dll, PrintHTML " + sURL);

But it is not working as well

function printPartOfPage(elementId)
        {
         var printContent = document.getElementById(elementId);
         var windowUrl = 'about:blank';
         var uniqueName = new Date();
         var windowName = 'Print' + uniqueName.getTime();
         var printWindow = window.open(windowUrl, windowName, 'left=50000,top=50000,width=0,height=0');
         printWindow.document.write(printContent.innerHTML);
         //var sURL = document.location.href;
         //var WshShell = new ActiveXObject("wscript.shell");
         //WshShell.run("rundll32.exe c:\windows\system32\mshtml.dll, PrintHTML " + windowUrl);
