Printer with interchangeable printing heads.

摘要

An ink jet printing head (14) is mounted on a movable carriage (13) and a fixing device (32) removably fixes the head (14) by means of a hook (111) adapted to cooperate with a shoulder of the head (14) or an alternative printing head (16) of the wire type. An electronic control unit (22) controls a control device (156) adapted to recognise which type of head is mounted on the carriage (13) and actuates it.
