Я хочу напечатать на принтере Bluetooth текст с изображением, которое находится на моем телефоне Android, но текст успешно распечатан, а изображение не напечатано на бумаге.

Я использовал следующий код:

public class SendingdataActivity extends Activity {
/** Called when the activity is first created. */
private BluetoothAdapter mBluetoothAdapter = null;
static final UUID MY_UUID =
UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66");
static String address = "50:C3:00:00:00:00";

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
Toast.makeText(this,
"Bluetooth is not available.",
Toast.LENGTH_LONG).show();
finish();
return;
}


if (!mBluetoothAdapter.isEnabled()) {
Toast.makeText(this,
"Please enable your BT and re-run this program.",
Toast.LENGTH_LONG).show();
finish();
return;
}
final SendData sendData = new SendData();
Button sendButton = (Button) findViewById(R.id.send);
sendButton.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
sendData.sendMessage();
}
});
}
class SendData extends Thread {
private BluetoothDevice device = null;
private BluetoothSocket btSocket = null;
private OutputStream outStream = null;

public SendData(){
device = mBluetoothAdapter.getRemoteDevice(address);
try
{
 btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
}
catch (Exception e) {
// TODO: handle exception
}
mBluetoothAdapter.cancelDiscovery();
try {
btSocket.connect();
} catch (IOException e) {
try {
btSocket.close();
} catch (IOException e2) {
}
}
Toast.makeText(getBaseContext(), "Connected to " + device.getName(),    
Toast.LENGTH_SHORT).show();
try {
outStream = btSocket.getOutputStream();
} catch (IOException e) {
}
}

public void sendMessage()
{
try {
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.white);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100,baos); //bm is the bi,tmap object
byte[] b = baos.toByteArray();
Toast.makeText(getBaseContext(), String.valueOf(b.length), Toast.LENGTH_SHORT).show();
outStream.write(b);
outStream.flush();
} catch (IOException e) {
}
}
}
}

Этот код работает и печатать только текст на бумаге.

Благодарю.
