Discover paired printers

I'm following the ZSDK_DemosAndroid project to discover bluetooth paired Zebra Printer's so as to get their mac address.My code for this runs on my main Activity and is like this,

 

new Thread(() -> {

  Looper.prepare();

   try {

 

BluetoothDiscoverer.findPrinters(this, new DiscoveryHandler() {

 

   @Override
   public void foundPrinter(DiscoveredPrinter discoveredPrinter) {  runOnUiThread(() -> System.out.println("FOUND PRINTER " + discoveredPrinter));}

 

   @Override
   public void discoveryFinished() {runOnUiThread(() -> System.out.println("FINISHED DISCOVER"));}

 

   @Override
   public void discoveryError(String s) {}

 

  });

  } catch (ConnectionException e) {e.printStackTrace();} finally {Looper.myLooper().quit();}

}).start();

 

Although i do have a paired printer, foundPrinter() never runs but discoveryFinished() does.Thus i don't get the connected Printer.Could this be permission-related?I've already set the following permissions in my manifest though.

 

<uses-permission android:name="android.permission.BLUETOOTH" />

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

I have a similar behavior.

I have a similar behavior. The BluetoothDiscoverer will return a list of discoverable, unpaired printers, but it will not return printers that have already been paired. Very frustrating.
