How to print the image on the MZ220 printer from the Android application?

I have a Zebra MZ220 portable Bluetooth printer.

Currently, I can print text / line on a printer through an Android app using the following code ...

private static void sendZplOverBluetooth(final String theBtMacAddress, final String Data) {
        new Thread(new Runnable() {
            public void run() {
                try {
                   ZebraPrinterConnection thePrinterConn = new BluetoothPrinterConnection(theBtMacAddress);
                   Looper.prepare();
                   thePrinterConn.open();
                   String zplData = Data;
                   thePrinterConn.write(zplData.getBytes());
                   Thread.sleep(500);
                   thePrinterConn.close();
                   Looper.myLooper().quit();
                } 
                catch (Exception e) {
                   e.printStackTrace();
                }
           }
       }).start();

}

I want to know if there is a way to print the image on the printer through the Android application, if so, how? The image is saved on the SD card. Any help? thank

Yes there is! Check out the developer demos that appeared in the developer demos that came with the SDK

<install_dir>\android\<version>\demos\src\com\zebra\android\devdemo\imageprint\ImagePrintDemo.java

Here's how you get a bitmap:

BitmapFactory.decodeFile (file.getAbsolutePath ())

and you can transfer this to a printer using

getGraphicsUtil(). printImage (pathOnPrinter, bitmap, [x], [y])
