Change I printed in bold (8)
I believe the answer is:
intrepid
'bold' is the definition.
(similar in meaning)
'change i printed' is the wordplay.
'change' indicates anagramming the letters.
'i'+'printed'='iprinted'
'iprinted' is an anagram of 'INTREPID'.
'in' is the link.
(Other definitions for intrepid that I've seen before include "Novel" , "Fearless, adventurous" , "Brave and fearless" , "'Brave, dauntless (8)'" , "Undaunted" .)
