Make an impression and so on with Henry (4)
I believe the answer is:
etch
'make an impression' is the definition.
(to etch is to make an impression in something)
'and so on with henry' is the wordplay.
'and so on' becomes 'etc' (synonyms).
'with' means one lot of letters go next to another.
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'etc'+'h'='ETCH'
(Other definitions for etch that I've seen before include "Use acid to design on metal or glass" , "Carve into surface of something" , "What most engravers presumably find easy to do" , "Cut deeply (with acid?)" , "Use acid to cut design" .)
