How to use a laptop screen as just a screen?

How can I use the "Print Screen" key on my laptop?

• on every keyboard there is always a "Print Screen" button/key. which is abbreviated as PrtSc or PrtScr on the button/key. And the "Print Screen" button/key on my keyboard is also the "End" button/key. The word "End" is in bold print, and in smaller grey print says "PrtSc" on the same button/key. But when I press that key, it only does what the "End" button/key would do. I want to use "Print Screen", but i don't know how. Since "End" and "Print Screen" are on the same button/key, i don't know how to use the "Print Screen" part. Do you know what I mean? Was it clear what I'm trying to ask?
