A printing apparatus includes a detection unit configured to detect that a predetermined user operation for unlocking an opening and closing portion is made on a predetermined screen displayed on a display portion in a state where the opening and closing portion is locked, an unlock unit configured to, in a case where the predetermined user operation is detected to be made, unlock the opening and closing portion, and an execution unit configured to, in a case where the predetermined user operation is detected to be made, execute predetermined preparation processing on a printing portion.

An image forming apparatus includes a carriage which is movably provided in a main scanning direction, a sub-carriage which is movably supported in a sub-scanning direction substantially orthogonal to the main scanning direction with respect to the carriage and performs recording on a recording medium from a held recording head, and a biasing member which is attached to a locking portion of the carriage and a locking portion of the sub-carriage and applies a force to the sub-carriage with respect to the carriage in three directions of the main scanning direction (first direction), the sub-scanning direction (second direction), and a vertical direction (third direction) substantially orthogonal to the main scanning direction and the sub-scanning direction.

In a liquid discharge device that discharges liquid while relatively rotating a medium and a discharge unit that discharges the liquid, a degradation of quality of the discharged liquid material caused by a difference of a relative moving distance between the medium and the discharge unit per unit time when the liquid is discharged is suppressed. The liquid discharge device includes a discharge unit (3) that discharges liquid from nozzles (4) to a medium (M), a rotating mechanism (14) that relatively rotationally moves the medium (M) and the discharge unit (3) around a rotation axis direction Z crossing a discharge direction of the liquid, and a control unit (6) that controls a discharge frequency of the liquid according to a relative moving distance between the medium (M) and the discharge unit (3) per unit time.

A thermal printer of an embodiment includes: a main body; an opening and closing lid; a printing portion that includes a platen and a thermal head; a locking portion locks the opening and closing lid; a detection unit that detects a predetermined pressing state between the thermal head and the platen when a sensor detects a detection target portion; a controller that prohibits printing by the printing portion when the detection unit does not detect the predetermined pressing state; and a biasing member that biases the main body and the opening and closing lid in a direction in which the main body and the opening and closing lid are separated from each other so that the sensor does not detect the detection target portion in a state where the opening and closing lid is not locked to the locking portion.

A liquid ejection apparatus includes a holding unit configured to hold a tray on which a container configured to contain liquid to be supplied to an ejection head is detachably mounted, a first restriction unit configured to be movable to a restriction position where the first restriction unit restricts pulling the tray out of the holding unit and to a non-restriction position where the first restriction unit does not restrict pulling the tray out of the holding unit, a connector configured to be in contact with a substrate of the container, and a second restriction unit configured to, in a case where the substrate is in contact with the connector and the first restriction unit is at the restriction position, restrict movement of the first restriction unit to the non-restriction position.
