Sort of printer that turns up in fire sale (5)
I believe the answer is:
laser
'sort of printer' is the definition.
'turns up in fire sale' is the wordplay.
'turns up' is a reversal indicator.
'in' indicates a hidden word.
'resal' is hidden within 'fire sale'.
'resal' backwards is 'LASER'.
'that' is the link.
(Other definitions for laser that I've seen before include "Scientific apparatus" , "scientific device" , "Surgical device" , "type of surgery" , "modern light industry" .)
