Examples of the present disclosure relate generally to a printing apparatus and, more particularly, to apparatuses, systems, and methods for printing utilizing laser print head and reactive media.

Print media conveyance method and apparatus thereof

Various embodiments disclose a method for operating a printer apparatus that includes a print head. The method includes causing a media hub to retract a media in a retract direction along a media path. Further, the method includes causing a first media sensor to generate a first signal during retraction of the media. Furthermore, the method includes monitoring the first signal to detect at least one of a leading edge or a trailing edge of a label of the plurality of labels. Upon detecting the at least one of the leading edge or the trailing edge of the label, causing the media hub to retract the media by at least a predetermined distance, wherein the predetermined distance is a distance between the print head and the first media sensor.

Methods, apparatus, and systems for improving printing precision

An example printing apparatus is illustrated. The printing apparatus includes a print engine assembly. The print engine assembly further includes a bottom chassis portion. The print engine assembly also includes a top chassis portion. The print engine assembly also includes a print head positioned within the top chassis portion. The print engine assembly also includes a plurality of offset pins coupled to the print head, where the plurality of offset pins abuts the bottom chassis portion, and where the plurality of offset pins enables the print head to be positioned at a predetermined distance from the bottom chassis portion.

Printing apparatus and a print engine assembly

Printing apparatus

A system to calculate line feed error in labels on a printer includes a holder assembly under the label line feed and before the printer burn line; a first sensor and a second sensor on the holder assembly, a fixed distance, L, between them; and a processor. The first sensor senses a first position of a label edge, LA. The second sensor senses a second position of the label edge, LB. The processor calculates the distance, LAB, between the first position and the second position and calculates the line feed error over the fixed distance, L, by taking the difference (L&#x2212;LAB). The processor calculates the feed correction to be done to the label, given by [(L&#x2212;LAB)/L]&#xd7;D, where D is a distance between the first sensor and the burn line of the printer. The processor instructs the printer line feed to implement the calculated feed correction.

A system to calculate line feed error in labels on a printer includes a holder assembly under the label line feed and before the printer burn line; a first sensor and a second sensor on the holder assembly, a fixed distance, L, between them; and a processor. The first sensor senses a first position of a label edge, L1A. The second sensor senses a second position of the label edge, L1B. The processor calculates the distance, L1AB, between the first position and the second position and calculates the line feed error over the fixed distance, L, by taking the difference (L&#x2212;L1AB). The processor calculates the feed correction to be done to the label, given by [(L&#x2212;L1AB)/L]&#xd7;D, where D is a distance between the first sensor and the burn line of the printer.
