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 associated with a label length;
• 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;
• an image verifier disposed adjacent to the media path and is downstream of the print head in the print direction;
• a first media sensor disposed between the print head and the image verifier, wherein the first media sensor is positioned at a predetermined distance from the image verifier, 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 an edge of a label of the plurality of labels;
• and
• in response to detecting the edge of the label during the retraction of the media along the media path:
• cause the media to retract by at least a first distance when the label length is greater than the predetermined distance between the image verifier and the first media sensor, and
• cause the media to retract by at least a second distance when the label length is less than the predetermined distance between the image verifier and the first media sensor, wherein the first distance is different from the second distance.
