Do impressive work (5)
I believe the answer is:
'do impressive work' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
This is the entire clue.
Can you help me to learn more?
(Other definitions for print that I've seen before include "Stamp" , "Copy of a film" , "Photographic image" , "Produce (books, etc)" , "Reproduce - publish" .)
