'prepare text for printing' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'works on the computer and french' is the wordplay.
'works on the computer' becomes 'types' (I can't justify this - if you can you should give a lot more credence to this answer).
'and french' becomes 'et' ('and' in French).
'types'+'et'='TYPE SET'

'to' acts as a link.
