Perfect print to order (8)
I believe the answer is:
copybook
'perfect' is the definition.
(I've seen this before)
'print to order' is the wordplay.
'print' becomes 'copy' (both can refer to printed text).
'to order' becomes 'book'.
'copy'+'book'='COPYBOOK'
(Other definitions for copybook that I've seen before include "Perfect (something blotted?)" , "Flawless" , "It contains models of writing for learners - don't blot it" , "It's used by schoolchild" , "Standard" .)
