Android调用蓝牙打印机

首先需要一个jar包,bluesdk,请自行百度。

具体排版样式跟网络打印机打印排版样式实现一样,这里不多叙述,只贴一个实现方法代码。蓝牙打印机使用前需要先跟手机配对,可以保存在本地,记录下地址,这里可以看到我每次调用这个方法 让线程休息了1s,原因是通过测试发现,当数据量特别大的时候,反复调用这个方法会出现丢失数据的现象,所以,每次执行完毕,都让他休息1s钟。

  public void printData(String data) {
    if (Settings.BluetoothDeviceAddress.equals("")) {
      MyToast.MyLogo(History.this, "打印错误,请检查打印机或重试");
      return;
    }
    System.out.println("Settings.BluetoothDeviceAddress:" + Settings.BluetoothDeviceAddress);
    try {
      Settings.BluetoothManager.setServerAddress(Settings.BluetoothDeviceAddress);
      if (!Settings.BluetoothManager.IsConnected()) Settings.BluetoothManager.ConnectServer();
      if (!Settings.BluetoothManager.IsConnected()) {
        MyToast.MyLogo(History.this, "打印错误,请检查打印机或重试");
      } else {
        Settings.BluetoothManager.PrintData(data);
      }
    } catch (Exception e) {
      MyToast.MyLogo(History.this, "打印错误,请检查打印机或重试");
      e.printStackTrace();
      try {
        Settings.BluetoothManager.shutdownServer();
        Settings.BluetoothManager.ConnectServer();
        Settings.BluetoothManager.PrintData(data);
      } catch (IOException e1) {
        MyToast.MyLogo(History.this, "打印错误,请检查打印机或重试");
        e1.printStackTrace();
        return;
      }
    }
    try {
      // 每次打印后休息1s
      Thread.sleep(1000);
    } catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
  }
