I have get this Solution - Converting the QR Code to an Image

var canvas = $('#qrcode canvas');
var img = canvas.get(0).toDataURL("image/png");
newWin = window.open("");
var ig = '<p style="text-align: center;">Powered by <img src="{{env('APP_URL')}}/public/{{$app_setting->webLogo}}"  alt="logo icon" style="width:40px;"></p>';
newWin.document.write("<h3 align='center'>QR Code</h3>");
newWin.document.write('<img style="display: block; margin: 0 auto;" src="' img '"/>');
newWin.document.write(ig);
setTimeout(function() {
newWin.print();
newWin.close();
}, 250);
}
