print.always_print_silent is not working.
I am developing a Point of Sale application and want it to specifically run on Firefox. I am running Firefox 45.0.2
I created a boolean entry print.always_print_silent in about:config to enable silent printing but it is not working. Print dialog is still showing. How can I correct it ?

After a cross check now I found that it is working for all other pages except one. Even my other local developed pages are sent to printer without dialog. Following is the code for the page I want to print :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html;charset=utf-8" http-equiv="Content-Type"> <meta content="utf-8" http-equiv="encoding"> <title>Arfat Dairy</title> <style> body{width:68mm; font-family:'Calibri'; margin:10px;} h1{font-size:26px; line-height:28px; margin:0px; padding:0px;} h3{font-size:30px; margin:20px;} h4{font-size:20px; line-height:20px;} #wrapper{border:1px solid #000; width:68mm;} </style> </head> <body> <div id="wrapper"> <h1 style="text-align:center; font-size:36px; margin:0px;">ARFAT DAIRY</h1> <h5 style="text-align:center; margin:0px;">RISHI TOLA, CHOWK ROAD, FATEHGANJ, FAIZABAD</h4> <h4 style="text-align:center; margin:0px;">Permission Slip</h3> <table width="100%" style="font-size:20px; text-align:center;"> <tr> <td align="right">Date : <b>15-04-2016 <b style="font-size:16px;">01:04:34</b></b></td> </tr> <tr> <td>Sorry you have already received your <b style="font-size:26px;">BUFFALO MILK on 2016-04-15 00:04:34</b></td> </tr> </table> </div> </body> </html>

It is easier to share HTML on a site like Pastebin, to avoid the wiki engine trying to interpret it.
I can't think of any HTML that should cause Firefox to show the Print dialog for just the one page out of all the pages you tested. Is there any difference in how it is presented, for example, is it displayed in a frame or iframe?
