The Free On-line Dictionary of Computing (30 December 2018):

output device

    Equipment connected to a computer that is used to
   transfer data out of the computer, either to a human user
   (e.g. as images on a monitor or sound from a loudspeaker)
   or to some form of permanent record (e.g. printed text).
   Most output devices are electronic with electromechanical
   components (e.g. a printer or loudspeaker) and/or
   electro-optical (e.g. a display screen).

   Storage devices such as disk drives and magnetic tape
   drives act as both input devices and output devices (they
   are "read-write" devices), others such as some CD-ROMs may
   be input only ("read-only").
