Optimal alignment of a printhead in a thermal printing apparatus

A printing assembly comprising:

• a printhead bracket having a first lower lateral surface and a longitudinal channel parallel to a longitudinal edge of the printhead bracket;
• an alignment adjuster having a second upper lateral surface and a second lower lateral surface,
• wherein the second upper lateral surface of the alignment adjuster is adjacent to the first lower lateral surface of the printhead bracket, and wherein the second upper lateral surface of the alignment adjuster comprises a gear rack, and
• wherein the second lower lateral surface of the alignment adjuster comprises a protrusion, and
• wherein the alignment adjuster includes a slot along a transverse edge of the alignment adjuster;
• a printhead having a third upper lateral surface and a third lower lateral surface, wherein the third upper lateral surface of the printhead is adjacent to the second lower lateral surface of the alignment adjuster, and
• wherein the third lower lateral surface of the printhead comprises at least one burn line, and
• wherein the third upper lateral surface of the printhead comprises a groove configured to receive the protrusion of the second lower lateral surface of the alignment adjuster;
• and
• a plurality of fasteners comprising at least one of a lateral adjustment fastener, a rotational adjustment fastener, and a set of additional fasteners,
• wherein the lateral adjustment fastener is arranged laterally on the second upper lateral surface of the alignment adjuster through the longitudinal channel of the printhead bracket,
• wherein the rotational adjustment fastener is received in the slot of the alignment adjuster,
• wherein the set of additional fasteners is received in a set of slots aligned in parallel in each of the printhead bracket, the alignment adjuster, and the printhead.

A printer comprising a printing assembly, the printing assembly comprising:

• 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;
• a plurality of fasteners, wherein the plurality of fasteners comprises at least one selected from a group of:
• a lateral adjustment fastener operatively engaged with the alignment adjuster;
• and
• a rotational adjustment fastener operatively engaged with a transverse edge of the printhead.
