Print screen makes you 'lag' and freezes you for a second or so. Test it for yourself - get a friend, stand in a line with him, start auto-running at the same time and start spamming print screen - you will fall behind.
This may have some use, but I doubt it - still, it's an interesting thing to notice, I wonder what it looks like from the perspective of other players? Can someone test?
