Printed stationery (10)
I believe the answer is:
letterhead
'printed stationery' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for letterhead that I've seen before include "Address, name etc printed at top of notepaper" , "Printed address on stationery" , "Heading on stationery" , "Where name and address are shown" , "Preprinted name, address etc at top of notepaper" .)
