Abstract: A printing apparatus includes an automatic opening mechanism for an opening/closing cover, a carriage that has a print head configured to perform printing on a medium and that moves in a direction intersecting a transport direction of the medium, and a discharge portion that is exposed in a state in which the opening/closing cover is opened and that discharges a printed material. The automatic opening mechanism includes a lever for releasing maintenance of a closed state of the opening/closing cover by movement of the carriage. The discharge portion discharges the printed material outside the apparatus. The automatic opening mechanism is arranged so as to overlap a discharge opening region of the discharge portion in a height direction.
