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 = ''; document.body.insertAdjacentHTML('beforeEnd', PrintCommand); PrintCommandObject.ExecWB(6, -1); PrintCommandObject.outerHTML = ""; } else { window.print();}
