What is my capture?

Print screen, if on the computer, is a process that u could get the image on the screen by using it.
There is a print screen key on ur keyboard. Press it, u will get a full screen capture, then u can paste it in any graphic editors like MS Paint.
If u wanna capture anything on the screen, i recommend u try PCHand Screen Caputre. It could help u capture anything. Im using it, it is easy to use, even for a novice. I think it is pretty good.
