Trips learner, shattering computer peripheral (5,7)

I believe the answer is:

laser printer

'computer peripheral' is the definition.
(I've seen this before)

'trips learner shattering' is the wordplay.
'shattering' is an anagram indicator.
'trips'+'learner'='tripslearner'
'tripslearner' anagrammed gives 'LASER PRINTER'.

(Another definition for laser printer that I've seen is " Computer peripheral".)

I've seen this clue in The Times.
