window.print() not working in IE

Add these lines after newWin.document.write(divToPrint.innerHTML)

newWin.document.close();
newWin.focus();
newWin.print();
newWin.close();

Then print function will work in all browser...

Add newWin.document.close();, like so:

function printDiv() {
   var divToPrint = document.getElementById('printArea');
   var newWin = window.open();
   newWin.document.write(divToPrint.innerHTML);
   newWin.document.close();
   newWin.print();
   newWin.close();
}

This makes IE happy. HTH, -Ted

function printDiv() {
    var divToPrint = document.getElementById('printArea');
    newWin= window.open();
    newWin.document.write(divToPrint.innerHTML);
    newWin.location.reload();
    newWin.focus();
    newWin.print();
    newWin.close();
}
