Sets about Republican involved with hard copies (9)
I believe the answer is:
Here is my best explanation:
'hard copies' is the definition.
'sets about republican involved with' is the wordplay.
'sets' becomes 'puts' ('put' can be a synonym of 'set'**).
'about' is an insertion indicator.
'republican' becomes 'r' (abbreviation).
'involved with' becomes 'into' (I've seen this before).
'puts' placed around 'rinto' is 'PRINTOUTS'.
(Other definitions for printouts that I've seen before include "Computer documents" and "Hard copies of computer documents".)
