Printing with bluetooth in phonegap

I'm needing of help for printing text in my aplication phonegap through of bluetooth of device...

I'm using this plugin for phonegap: http://ift.tt/1tLMPEU

but not working. I'm testing the android, I performed pairing the device put in applying appears that there is no active devices ...

Added this way in my files ...

Config.xml:

<feature name="BluetoothSerial">
            <param name="android-package" value="com.megster.cordova.BluetoothSerial"/>
        </feature>

<source-file src="src/android/com/megster/cordova/BluetoothSerial.java"
        target-dir="src/com/megster/cordova"/>
    <source-file src="src/android/com/megster/cordova/BluetoothSerialService.java"
        target-dir="src/com/megster/cordova"/>

    <!-- kludge for 2.9 -->
    <source-file src="src/android/org/apache/cordova/api/Dummy.java"
        target-dir="src/org/apache/cordova/api"/>

AndroidManifest:

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

This correct? What was missing?
