Hi,
Try like this
In your aspx

OnNavigate="CrystalReportViewer1_Navigate" HasCrystalLogo="False" HasToggleGroupTreeButton="False"

Width="350px" HasToggleParameterPanelButton="False" ToolPanelView="None" Height="50px"

EnableDrillDown="False" EnableParameterPrompt="False" />

function printCrystal() {

var printContent = document.getElementById('printReady');

var windowUrl = 'about:blank';

var uniqueName = new Date();

var windowName = 'Print' + uniqueName.getTime();

var printWindow = window.open();

printWindow.document.write(''+printContent.innerHTML+'');

printWindow.focus();

printWindow.print();

printWindow.close();

}
