My aim is to use the simplest way to print from a Bluetooth printer.

Screen Shots

Works only on supported printers

Usage

Step 1

allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Step 2

Add dependencies in build.gradle.

    dependencies {
       compile 'com.github.barisatalay:thermalprinterhelper:v1.2.2'
    }

Step 3 (Use of library)

Create BluetoothProvider;

   //Parameter 1: Activity,
   //Paremeter 2: BluetoothCallback interface
   BluetoothProvider bluetoothProvider = new BluetoothProvider(this, this);

Code to connect to the terminal

   //Control of required permissions.
   //Check terminal device pair / unpair control.
   //Connect to BluetoothSocket
   //If don't have any pair devices, if it have permission open devices activity 
   bluetoothProvider.connect()

If you want print test page

   bluetoothProvider.printText(bluetoothProvider.prepareTestData())

Define the base64Image to print

   //Works only on supported printers
   bluetoothProvider.printImageText("...")

Define the text to print

   bluetoothProvider.printText("This is PRINT EXAMPLE!!!")

Define the byte array to print

   //This value default false
   bluetoothProvider.printByteArray(PrinterCommands.FEED_LINE_2)

If you do not want to open the terminal device screen use this method

   //This value default false
   bluetoothProvider.showPrinterListActivity(false);
   bluetoothProvider..setDeviceAddress("98:D3:31:B2:A5:AA");

!!IMPORTANT!! You are must be defined this codes

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


   <activity
            android:name="com.atalay.bluetoothhelper.View.PrinterList.PrinterListActivity"
            />
