You might want to take screenshot your Kindle Fire tablet screen for any reason like for trouble shooting or sharing your game score on FaceBook or send few instructions to your family members etc. Fortunately, It is easy to take screenshots on the new Kindle Fire 2nd generation devices.
It was hard to take screenshots on 1st generation Kindle Fire tablet. You had to Android SDK etc and connect to your computer etc just to take a screenshot. We are used to Print Screen function on computers.
How to take screenshot of Kindle Fire HD or Kindle Fire 2
1. Press and hold Volume Down & Power buttons simultaneously. Your Kindle Fire screen flickers and takes a snapshot of tablet screen.
2. You can find the saved screenshot images in Photos > Screenshots. Make sure to select Device tab at the top as shown below.

You can send saved screenshot via email, skype etc. I did not any option to send them via Bluetooth. It seems Kindle Fire has limited sharing options.
