'one who runs a' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'small computer peripheral' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'computer peripheral' becomes 'printer' (I've seen this before).
's'+'printer'='SPRINTER'

Can you help me to learn more?
