Print out again, in entirety, permit (6)
I believe the answer is:
retype
'print out again' is the definition.
(type out again)
'in entirety permit' is the wordplay.
'in' says the answer is hidden in the clue.
'RETYPE' is hidden within 'entirety permit'.
(Other definitions for retype that I've seen before include "Repeat work in pool" , "Key in again" , "Put into printed characters again" , "impress again" , "Produce amended" .)
