Print Screen
What does the print screen key do in macOS? Is there a driver for macOS to make it work like it would on Microsoft Windows?

Not every key on your Windows-oriented keyboard is supported in macOS — unless you are running Windows in Boot Camp, or a Virtual Machine where Windows honors the Print Screen button. Apple keyboards do not have a Print Screen button, because that functionality is not implemented in macOS.
