How to take printout of my layout using wifi printer?

I am developing Restaurant application. After the order completion, i need to display bill (items price and total amount) in AlertView.

Is it possible to take print out of that AlertView in wifi printer? How to make it?

Yes it is possible to print a layout create a bitmap from the layout and send a intent to the printer app as in the following code

    yourRootLayout.setDrawingCacheEnabled(true);
    yourRootLayout.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
    yourRootLayout.buildDrawingCache();

    Bitmap dummyImageBitmap = Bitmap.createBitmap(yourRootLayout
            .getDrawingCache());
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    dummyImageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
    byte[] photoArray = out.toByteArray();
    yourRootLayout.setDrawingCacheEnabled(false);

    try {

        File file = new File(getFilePath());//path to sdcard
        if (file.exists()) {
            file.delete();
        }
        FileOutputStream outPut = new FileOutputStream(file);
        outPut.write(photoArray);
        outPut.flush();
        outPut.close();
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_SEND);
        intent.setType("application/pdf");
        intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));
        startActivity(intent);


    } catch (Exception e) {
        throw new Exception("Error generating file", e);
    }

now this will pop a a list of apps you will have to select the printers app that allows printing via wifi
