A printer includes a printing mechanism configured to print on a printing object held by a holder, a reciprocating mechanism configured to move the holder in a first direction and a second direction opposite to the first direction, and controller circuitry configured to control the printing mechanism and the reciprocating mechanism. When the controller circuitry executes a superimposed printing on the printing object, the controller circuitry causes the printing mechanism to execute a pre-printing process and a post-printing process that prints on the image printed by the pre-printing process while the holder is moved in the first direction from a waiting position, and the controller circuitry causes the reciprocating mechanism to stop a movement of the holder for a predetermined time period after the pre-printing process is terminated and the holder has returned to the waiting position.
