How do you use print screen key to copy a page?

Use the print screen key, u will get the full screen capture, press CTRL+Pr Scrn button, uwill get active window. But u wanna copy a page and if the page it too long, i think the print screen button couldnot help u.

So i recommend u try PCHand Screen Caputre. It could help u capture anything. It offers many different capture modes inculding a scrolling window. Using this mode u could get a long page directly without any treatment. Im using it, it is easy to use, even for a novice. I think it is pretty good. Hope it could help.
