If you already know how the Print Screen key works then maybe your Print Screen key is defective.
1. Have you tried another keyboard?
2. Is the information appearing in your clipboard viewer after using the key?
3. When was it last working?
This sort of information is more useful than ranting about others.
There is nothing you normally have to change to get this function.
If it is not working then you have a fault which requires diagnosis.
Always pop back and let us know the outcome - thanks
