Depricated networking that apple developed that supported network device discovery and configuration. It's quite legacy.
 
Some old ethernet printers hanging around that use it though.

And if you turn it off, sometimes some of the printers and computers file sharing will vanish.

Mainly the Apple File stuff is likely all that is left, along with some old printers.

Some interesting trivia about AppleTalk...

AppleTalk was called that originally because of the same apple orchard acid trip that gave Steve Jobs the idea to call the company "Apple."

The Autobiography of Steve Jobs said:
(top of page 48)
"... As I climbed up the ladder I could see the whole orchard laid out before me, the trees swaying in the summer breeze, their outstretched leaves touching each other in turn, as if tickling each others palms with some secret leafy handshake. All of a sudden, "boom!" I had another realization. The trees were using the wind to talk to each other! Each tree would lean over and touch the leaves of the tree next to it passing the whispered messages on down the line.

I threw my arms up in the air and made the "Y" shape to better tune myself to the universe and the amazing spectacle laid out before me. The more I tuned in the more I could hear. Fantastic conversations about sugar and soil, about the weather and ants who lived in the wooded area to the north. My mind was filled with so many snippets of conversation that it seemed it was about to explode. The orchard was alive.

'The Apples are talking to me!' I shouted from the top of my ladder, and began to laugh uncontrollably.

The Apples are talking! The Apples are talking! The Apples are talking! I shouted over and over again .... "

There's more of course. Very moving stuff. I recommend the book to everyone.
