Android調用藍牙打印機

首先需要一個jar包，bluesdk，請自行百度。

具體排版樣式跟網絡打印機打印排版樣式實現一樣，這里不多敘述，只貼一個實現方法代碼。藍牙打印機使用前需要先跟手機配對，可以保存在本地，記錄下地址，這里可以看到我每次調用這個方法 讓線程休息了1s，原因是通過測試發現，當數據量特別大的時候，反復調用這個方法會出現丟失數據的現象，所以，每次執行完畢，都讓他休息1s鍾。

  public void printData(String data) {
    if (Settings.BluetoothDeviceAddress.equals("")) {
      MyToast.MyLogo(History.this, "打印錯誤，請檢查打印機或重試");
      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, "打印錯誤，請檢查打印機或重試");
      } else {
        Settings.BluetoothManager.PrintData(data);
      }
    } catch (Exception e) {
      MyToast.MyLogo(History.this, "打印錯誤，請檢查打印機或重試");
      e.printStackTrace();
      try {
        Settings.BluetoothManager.shutdownServer();
        Settings.BluetoothManager.ConnectServer();
        Settings.BluetoothManager.PrintData(data);
      } catch (IOException e1) {
        MyToast.MyLogo(History.this, "打印錯誤，請檢查打印機或重試");
        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();
    }
  }
