If you don't want it to do PostBack then why use an ASP.NET button?
you can use any html tag from image to button according to your needs.

Then you can add onClick JS and you get what you wanted, you can call PrintGridView();
and\or other methods if you like.

Cheers,
Edo

Place this javascript on the Memo_print.aspx page

JavaScript

window.onload=function PrintGridView()
            {
                var gridInsideDiv = document.getElementById('grd_div');
                /*var printWindow = window.open('gview.htm','PrintWindow','letf=0,top=0,width=800,height=600,toolbar=1,scrollbars=1,status=1');*/
                var printWindow = window.open();
                printWindow.document.write(gridInsideDiv.innerHTML);
                printWindow.document.close();
                printWindow.focus();
                printWindow.print();
                printWindow.close();
            }
