-'''Location:''' Place the image in the ''''assets'''' folder of your application project.
-'''Image Specifications:'''
-* '''Width:''' The width of the image should be 384 dots or less.
-* '''Height:''' The height should be a multiple of 24 dots. If the height is not a multiple of 24, the excess will result in blank printing at the bottom of the image.
-== Printing the Image ==
-'''Using the Print Image API:''' To print the image, call the print image API provided in the Java API. The necessary code snippet for this process is as follows:
-<syntaxhighlight lang="java">
-    public void printBitmap(Map<String, Object> param, ActionCallback callback) {
-        Bitmap bitmap =null;
-        try {
-            bitmap = BitmapFactory.decodeStream(mContext.getResources().getAssets()
-                    .open("photo.bmp"));
-        } catch (IOException e1) {
-            // TODO Auto-generated catch block
-            e1.printStackTrace();
-        }
-        try {
-            device.printBitmap(bitmap);
-            sendSuccessLog(mContext.getString(R.string.operation_succeed));
-        } catch (DeviceException e) {
-            e.printStackTrace();
-            sendFailedLog(mContext.getString(R.string.operation_failed));
-        }
-    }
