Question

How to save screenshot of the application screen or search for a wifi printer and print the application screen?

Answer 1

To save the screen shot:

View view=mTextView.getRootView(); /*mTextView is a textview on my screen. Instead you can take any of your views(imageview, textview or even button)*/
view.setDrawingCacheEnabled(true);
Bitmap bmp=view.getDrawingCache();

Now, you save bitmap to a file to save it.

EDIT:
I wonder if you are not asking about programmatic way? If you are looking for manual way, Raj’s answer may help you.
