Various embodiments illustrated herein disclose a printing apparatus comprising a media supply spool configured to supply print media along a media path. The printing apparatus further comprises a first media sensor positioned in a first plane in the printing apparatus. Further, the printing apparatus comprises a second media sensor positioned in a second plane in the printing apparatus. Additionally, the printing apparatus comprises a first media guide defining a section of the media path, wherein extremities of the first media guide are positioned to be at a negative offset from the second plane.

Media guide assembly for printing apparatus

A verifier and printer assembly are provided. The verifier and printer assembly include a verifier module and a printer. The verifier has a magnetic docking element and the printer includes a docking portion operable to dock the verifier module. The magnetic docking element and the docking portion interact with each other to removably couple the verifier module to the printer. A magnetic attachment system for the verifier module and methods for removably coupling the verifier module and the printer for verification of a printed machine-readable symbol are also provided.

Removably couplable printer and verifier assembly

Provided herein is a printer comprising a printing assembly. The printing assembly comprises a printhead bracket fixedly attached to the printer, a printhead that defines a groove, the printhead aligned at a first alignment, an alignment adjuster fastened between the printhead bracket and the printhead, and a plurality of fasteners operatively engaged with the alignment adjuster. The alignment adjuster comprises a gear rack that is adjacent to the printhead bracket, and a protrusion that is received by the groove of the printhead. The plurality of fasteners comprises at least one selected from a group of a lateral adjustment fastener operatively engaged with the gear rack, and a rotational adjustment fastener operatively engaged with a transverse edge of the printhead. The lateral adjustment fastener is configured to provide lateral movement to the alignment adjuster and the printhead. The rotational adjustment fastener is configured to provide rotational movement to the printhead.

Optimal alignment of a printhead in a thermal printing apparatus

Media path for print registration

The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes 'print as you glide' (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.

Method and apparatus for printing

Provided herein is a printing apparatus including a printhead movable between a first position and a second position. The printhead includes a first substrate and a second substrate. The first substrate and the second substrate define at least a first burn line and a second burn line, respectively, of heating elements disposed adjacent to a first edge and a second edge, respectively of the printhead. A printhead bracket receives the printhead in one of the first position or the second position. In the first position, the heating elements of the first burn line perform a printing operation and the printhead bracket is configured to preclude operation of the heating elements of the second burn line. In the second position, the heating elements of the second burn line perform a printing operation, and the printhead bracket is configured to preclude operation of the heating elements of the first burn line.

Printhead for a printing apparatus

Printing apparatus

Provided herein is a printing apparatus that includes a printhead assembly and a plurality of printhead pressure load modules that are adjustable on a shaft of a printhead pressure load assembly and engaged with a printhead member. The printhead pressure load module has a hollow housing, a plunger member, and a rotary cam. The plunger member and the rotary cam are movably engaged in the hollow housing. The rotary cam includes a plurality of channel members defined at an outer surface. Each channel member has a depth that is different from a depth of an adjacent channel member. A movement of the plunger member inwardly through the hollow housing defines a position of the rotary cam along the longitudinal axis with respect to the hollow housing. Position change of the rotary cam defines a force that acts on a pressure contact member and adjusts a load on the printhead assembly.
