How to print data on a new line and set page layouts to print data from android

I am creating an Android application that consists of printing data from a usb connected printer. This is where I want to set page layouts like new line prints when they are reached at the end of the page and page border, etc. Is this possible with software processing. Please help me how to do this.

This is what I did to print the data:

public class DemoPrinter extends Activity {

    private final String ACTION_USB_PERMISSION = "com.android.example.USB_PERMISSION";
    Button create_file;
    PendingIntent mPermissionIntent;
    UsbManager usbManager;
    UsbDevice device;
    EditText print_text;
    UsbDevice printer = null;
    private static final int PRINTER_VENDOR_ID = 1256;
    private String filename = "MySampleFile.txt";
    private String filepath = "PanelFilesstorage";
    File myInternalFile;

    String data= "This is a sample text";

    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        try 
        {
            setContentView(R.layout.activity_demo_printer);
            ContextWrapper contextWrapper = new ContextWrapper(getApplicationContext());
            File directory = contextWrapper.getDir(filepath, Context.MODE_PRIVATE);
            myInternalFile = new File(directory , filename);



            print_text = (EditText)findViewById(R.id.editText_printer);

            usbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
            HashMap<String, UsbDevice> deviceList = usbManager.getDeviceList();

            if (deviceList.size() <= 0) 
            {
                Toast.makeText(getApplicationContext(), "Info: No device found", Toast.LENGTH_SHORT).show();
            }
            else 
            {
                Toast.makeText(getApplicationContext(), "No of devices"+deviceList.size(), Toast.LENGTH_SHORT).show();
                ((TextView) findViewById(R.id.textView_devices))
                        .setText("No of device : " + deviceList.size());
            }
            Iterator<UsbDevice> deviceIterator = deviceList.values().iterator();
            int count = 0;
            mPermissionIntent = PendingIntent.getBroadcast(getBaseContext(), 0,
                    new Intent(ACTION_USB_PERMISSION), 0);
            while (deviceIterator.hasNext()) {
                count++;
                device = deviceIterator.next();
                Log.i("info", "Device No " + count + "........");
                Log.i("info", "Vendor id : " + device.getVendorId());
                Log.i("info", "Product id : " + device.getProductId());
                Log.i("info", "Device  name : " + device.getDeviceName());
                Log.i("info", "Device class : " + device.getClass().getName());
                Log.i("info", "Device protocol: " + device.getDeviceProtocol());
                Log.i("info", "Device subclass : " + device.getDeviceSubclass());
                if (device.getVendorId() == PRINTER_VENDOR_ID) {
                    printer = device;
                    break;
                }
            }
