I have found the solution to the problem

In Chrome:

• step 1:

config run chrome silent printing on mode --kiosk-printing edit target on chrome shortcut properties Ex:"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk-printing "http://localhost:8080/this"

• step 2:

code

var iframe = document.createElement('iframe');
            document.body.appendChild(iframe);
            iframe.style.display = 'none';
            iframe.onload = function() {
                setTimeout(function() {
                    iframe.focus();
                    iframe.contentWindow.print();
                }, 0);
            };
            iframe.src = _blobUrl;

In Firefox:

• step1: config printing silent

goto about:config create new Boolean preference name="print.always_print_silent" Value=true

• step 2: code

  var myWindow = window.open(_blobUrl, '_blank', 'width=800,height=600'); myWindow.focus(); myWindow.print(); myWindow.close();
