Is there something more required to take screen shots than merely pressing print screen button??

I'm running a windows 8 based operating system on an hp laptop. perhaps there is some setting that I need to activate that I am not aware of.
Thanks for any information that will aide me on this lack of knowledge on my part of the new windows.
