Printscreen Not Working

I'd wanted to copy a screenshot from the video of What is Love by Never Shout Never but I didn't know how to use Printscreen on my netbook. I'd tried to press Printscreen button but when I pasted it into paint, there is no photo came out. I  am used to click just printscreen on my desktop computer with my keyboard but this netbook has this button with dual function. I just learned that you have to hold down Fn (it's located between Ctrl key and Home) while pressing PrtSc button.

So that solved my computer ignorance for today. :D
