When you use JavaScript's window.print() to print a Web page in IE, by default, it prompts IE's printer dialog box. To avoid this, use the following JavaScript code:

if (navigator.appName == "Microsoft Internet Explorer")
{
var PrintCommand = '<object ID="PrintCommandObject" WIDTH=0 HEIGHT=0
CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></object>';
document.body.insertAdjacentHTML('beforeEnd', PrintCommand);
PrintCommandObject.ExecWB(6, -1); PrintCommandObject.outerHTML = "";
}
else {
window.print();
}
