Misprint (4)
I believe the answer is:
typo
'misprint' is the definition.
(I know that misprint can be written as typo)
This is all the clue.
(Other definitions for typo that I've seen before include "Printer's error" , "Keyboard slip-up" , "Mistake in printed matter, in short" , "literal, perhaps" , "Spelling mistake" .)
