Turning to AI, teen derided physical work (4,4,7)

I believe the answer is:

dead tree edition

I'm a little stuck... Click here to teach me more about this clue!

'physical work' is the definition.
The definition suggests a singular noun which matches the answer.

'turning to ai teen derided' is the wordplay.
'turning' indicates an anagram.
'to'+'ai'+'teen'+'derided'='toaiteenderided'
'toaiteenderided' with letters rearranged gives 'DEAD TREE EDITION'.

Can you help me to learn more?

(Other definitions for dead tree edition that I've seen before include "Paperback" , "hard copy" .)

I've seen this clue in The Independent.
