Hi,
We have a native android app which you can print invoice an waybill from it via bluetooth. i used default bluetooth adapter. When i hit print button from app, the bluetooth printer prints what i sent with no problem, but when i print again, printing text is corrupted. At the half of the document printer just stop and rewind the paper and print the left of the text that i sent. At that point i switch-off the printer and switch on again. then i press print from app. Again printer works fine in the first print. but when i print second copy, printer fail again. i couldnt understand whats going on. If i have a problem with the code or adapter that i used, i couldnt print any text message, but i have problem only in second copies.

Here is my code:

public BluetoothDevice FindPrinter() {
		BluetoothDevice currentDevice = null;

		try {
			mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
			if (mBluetoothAdapter == null) {
				throw new Exception("Bluetooth adaptorü bulunamadı");
			}
			if (!mBluetoothAdapter.isEnabled()) {
				Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
				Activity a = new Activity();
				a.startActivityForResult(enableBluetooth, 0);
			}
			Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
			if (pairedDevices.size() > 0) {
				for (BluetoothDevice device : pairedDevices) {
                                     if(device.getName().equals(SharedPreferenceSettings.getPrinterPort(context))) {
						currentDevice = device;
					}
				}
			}

		} catch (Exception e) {
			Toast.makeText(context, e.getMessage(), Toast.LENGTH_SHORT).show();
		}
		return currentDevice;
	}

public void Print() {

		try {
			int current = 0;
			FormatData();
			int line = 0;
			
			Method m = mmDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
			mmSocket = (BluetoothSocket) m.invoke(mmDevice, 1);
			mmSocket.connect();
			while (current < Data.length) {
				mmOutputStream = mmSocket.getOutputStream();
				int len = 256;
				if (current + 256 > Data.length) {
					len = Data.length - current;
				}
				byte[] temp = new byte[len];
				System.arraycopy(Data, current, temp, 0, len);
				int currentLine = CountLines(temp);
				line = line + currentLine;
				mmOutputStream.write(temp);
				current += len;
				Thread.sleep(1700);
			}
			mmOutputStream.close();
			if(mmSocket.isConnected())
				mmSocket.close();
		} catch (Exception e) {
			Log.e("Print ERROR", e.getMessage());
		}

	}
