Printing house that is making a gift (7)
I believe the answer is:
pressie
'a gift' is the definition.
(short for 'present')
'printing house that is' is the wordplay.
'printing house' becomes 'press' (I've seen this before).
'that is' becomes 'ie' (synonyms).
'press'+'ie'='PRESSIE'
'making' acts as a link.
(Other definitions for pressie that I've seen before include "Gift (colloq.)" , "Informally, offering" , "Something freely given" .)
