    url: "/aicmer/pdflicense",
    success: function (data) {
        var rawLength = data.length;
        var array = new Uint8Array(new ArrayBuffer(rawLength));
        for (var i = 0; i < rawLength; i++) {
            array[i] = data.charCodeAt(i) & 0xff;
        }
        var blob = new Blob([array], {type: 'application/pdf;charset-UTF-8'});
        // var fileName = 'PDF'+new Date().getTime()+'.pdf';
        //window.open(URL.createObjectURL(blob))
        $("#printIframe").attr("src", URL.createObjectURL(blob));
