如何从Android应用程序将图像打印到MZ220打印机？

Question

I have a Zebra MZ220 portable Bluetooth printer.

currently i am able to print text/string on the printer through my android application 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 i can print an image on the printer through my android application, if so how? The image is stored on the SD card. Any assistance? Thanks

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

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

Here is how you get a Bitmap:

BitmapFactory.decodeFile(file.getAbsolutePath())

and you can pass that to the printer via

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