title: Send Excel file to client's printer
body: <p>i have a PHP web site and i am writing some data to an Excel file. My Excel file can be downloaded with a button. It opens a window or download manager (if configured). So far everything is ok. Now i want to send this file <strong>automatically</strong> to the Client's default printer. When users click print, web page must send the "EXCEL FILE" to printer. NOT like the "window.print()" function in JavaScript.</p>
  
  <p>Is there a way to do this with javascript or AJAX ? Does the client have to download the Excel file in order to send it to default printer ? I tried to use a hidden "iframe" with "src = bla_bla.xls" but it automatically opens the download window.</p>
  
  <p>Briefly i want this <strong>Excel</strong> file, which is prepared on server, to be sent to <strong>client's default printer</strong> and open up the print options window.</p>
