Pos打印机制表符\t不起作用？

我是用蓝牙去连接Pos打印机，之后发现制表符不起作用，然后去阅读了一下打印机的SDK,发现需要提前设置水平指标位置 使用命令为ESC D:
代码如下：（outputStream是从连接好的socket中取到的输出控制流）
//set horizontal table charactor
outputStream.write(0x1B);//ESC
outputStream.write(0x44);//D
outputStream.write(9); //以下为8个制表位置
outputStream.write(16);
outputStream.write(25);
outputStream.write(33);
outputStream.write(41);
outputStream.write(49);
outputStream.write(57);
outputStream.write(65);
outputStream.write(0);//结束符
//test print string
outputStream.write('Hello\tWorld\n');
