Is it good for user experience to duplicate browser/keyboard functionality?

For example: to provide these links on a web-page.

"Back to top" link
"Print this page" link
"Add to Favorite" link
"Back" button/link
"Text zoom" button

Are they really create Site's usability and accessibility?

How screen reader will behave these links, will these confuse to screen reader users?
