an induction portion disposed at the second support body, the induction portion being configured to guide the suppression portion to a suppression release position in the opening operation of the printing head portion and guide the suppression portion to a suppression position in the closing operation of the printing head portion.
4. The printer according to claim 1 , wherein
the damper portion is constituted of a transparent material.
5. The printer according to claim 1 , wherein
the damper portion comprises:
a guide piece that contacts at least one side edge of the print medium to guide a feed of the print medium; and
