Considers the endless requirements in printing (6)
I believe the answer is:
thinks
'considers' is the definition.
The answer and definition can be both related to thinking as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?
'the endless requirements in printing' is the wordplay.
'endless' means to remove the last letter.
'requirements in printing' becomes 'inks' (I can't explain this - if you can you should believe this answer much more).
'the' with its last letter taken off is 'th'.
'th'+'inks'='THINKS'
Can you help me to learn more?
(Other definitions for thinks that I've seen before include "Exercises the mind" , "Ponders" , "Reflects, cogitates" , "Believes" .)
