Cannot print on Embedded printer

[weyotech]

I am testing this library on JP-Q2i POS Terminal PDA (Embedded printer is configured as Bluetooth device)
but I cannot print a text.

Printama.with(this).connect(new Printama.OnConnected() {
                    @Override
                    public void onConnected(Printama printama) {
                        printama.printText("TEST");
                    }
                });

Library connect with MPT-II but not start a print

I have found the bug in PrinterUtil.java
The problem is when receive uuids = null so to solve this problemi you should change code with this

        @Override
        protected BluetoothSocket doInBackground(BluetoothDevice... bluetoothDevices) {
            BluetoothDevice device = bluetoothDevices[0];
            UUID uuid;
            if (device != null) {
//                uuid = device.getUuids()[0].getUuid();
                ParcelUuid[] uuids = device.getUuids();
                uuid = (uuids != null && uuids.length > 0) ? uuids[0].getUuid() : UUID.randomUUID();
            } else {
                return null;
            }
            BluetoothSocket socket = null;
            boolean connected = true;
            try {
                socket = device.createRfcommSocketToServiceRecord(uuid);
                socket.connect();
            } catch (IOException e) {
                e.printStackTrace();
            } catch (Exception e2) {
                connected = false;
            }
            return connected ? socket : null;
        }
