The present disclosure discloses an operation panel for an imaging device and an imaging device thereof. The operation panel comprises: a panel body hinged to a connector through a pin shaft; a positioning system comprising a first ratchet wheel and a backstop, wherein the first ratchet wheel is sleeved on the pin shaft and coupled to the panel body, the backstop is arranged on the connector and configured to clamp the first ratchet wheel when the first ratchet wheel rotates reversely so as to position the first ratchet wheel, and the backstop is coupled to the connector and slides at least in a direction parallel to an axial direction of the pin shaft; and a driving system coupled to the backstop and configured to drive the backstop to slide at least in the direction parallel to the axial direction of the pin shaft.

An air bearing assembly is disclosed. The air bearing assembly may comprise a print component to interact with an imaging plate, the imaging plate being rotatable relative to the print component. The air bearing assembly may comprise an air bearing pad positioned adjacent to a surface of the imaging plate, the air bearing pad to generate a cushion of air to maintain a defined distance between the print component and the imaging plate. A method and a print apparatus are also disclosed.

A direct thermal printer including a latch assembly, a media storage assembly, a media centering assembly, a print assembly, and a temperature sensing member. The latch assembly includes a single latch lever in mechanical communication with latch tabs disposed in the cover of the printer that are received by openings in the base of the printer to engage and disengage the cover from the base. The media storage assembly includes media guides with removable tabs having more than one available position to provide storage of different size media. The media centering assembly includes pulley assemblies that bias the media guides towards each other to secure media between the media guides. The print assembly includes a platen disposed in the base of the printer having cams on each end that are rotatable and positioned to adjust printing characteristic of a printhead disposed in the cover.
