function print(o) {
        if (jspmWSStatus()) {
            var cpj = new JSPM.ClientPrintJob();
            if ($('#useDefaultPrinter').prop('checked')) {
                cpj.clientPrinter = new JSPM.DefaultPrinter();
            } else {
                cpj.clientPrinter = new JSPM.InstalledPrinter($('#installedPrinterName').val());
            }
            var esc = '\x1B';
            var newLine = '\x0A';

            <?php
            include "../conn.php";
            $id = $_GET['id'];
            $qry = mysqli_query($koneksi, "SELECT * FROM table WHERE id='$id'");
            $data = mysqli_fetch_array($qry);
            $agent_code = $data["agent_code"];
            $agent_name = $data["agent_name"];
            $achievement = $data["achievement"];
            ?>

            var cmds = esc + "@";
            cmds += esc + '!' + '\x38';
            cmds += 'COMPANY\n';
            cmds += newLine + newLine;

			// cmds += "\x1d\x6b\x04<?=$id?>\x00"; //BARCODE (BERHASIL TAMPIL)
			// cmds += esc + 'iQ\x04\x02\x00\x00\x00\x00\x02\x00123456789\\\ '; //QR CODE
            cmds += esc + 'i Q \x04 \x02 \x01 \x01 \x03 \x31 \x02 \x00 123 \\\ ';
            cmds += esc + 'i Q \x04 \x02 \x01 \x02 \x03 \x31 \x02 \x00 456 \\\ ';
            cmds += esc + 'i Q \x04 \x02 \x01 \x03 \x03 \x31 \x02 \x00 789 \\\ ';

            cmds += esc + '!' + '\x00';
            cmds += 'ID : ' + '<?=$id?>';
            cmds += newLine;
            cmds += 'AGENT CODE : ' + '<?=$agent_code?>';
            cmds += newLine;
            cmds += 'NAME : ' + '<?=$agent_name?>';
            cmds += newLine;
            cmds += 'ACHIEVEMENT : ' + '<?=$achievement?>\n';
            cmds += esc + '!' + '\x00'; //Character font A selected (ESC ! 0)
            cmds += newLine + newLine;

            cpj.printerCommands = cmds;
            cpj.sendToClient();
        }
    }
