Methods, apparatus, and systems for improving printing precision

A printer apparatus comprising:

• a printer housing having at least a printer media output;
• a media hub configured to receive a media roll and supply a media from the media roll along a media path in a print direction to the printer media output, wherein the media includes a plurality of labels;
• a print head disposed adjacent to the media path and is downstream of the media hub in the print direction, wherein the print head is configured to print content on the plurality of labels;
• a first media sensor disposed downstream of the print head in the print direction at a predetermined distance from the print head, wherein the first media sensor is disposed between the print head and the printer media output in the print direction, wherein the first media sensor is configured to generate a first signal indicative of a position of the plurality of labels on the media path;
• and
• a processor communicatively coupled to the media hub, the first media sensor and the print head, wherein the processor is configured to:
• cause the media hub to retract the media in a retract direction along the media path, wherein the retract direction is opposite to the print direction;
• monitor the first signal received from the first media sensor, during the retraction of the media along the media path, to detect at least one of a leading edge or a trailing edge of a label of the plurality of labels;
• and
• in response to detecting the at least one of the leading edge or the trailing edge of the label during the retraction of the media along the media path, cause the media to retract by at least the predetermined distance between the first media sensor and the print head to align the label with the print head.
