CONTROL OF LASER PRINTHEAD FOR WRITING OR ERASING CONTENT

A label modification unit may receive a label modification input that indicates a label modification associated with content being written to a label or erased from the label. The label modification unit may identify an area of the label that is associated with the label modification according to the label modification input. The label modification unit may determine, based on a size of the area, a spot size of a light beam that is configured to be emitted by a laser printhead to modify the content within the area. The label modification unit may determine, based on the spot size and the content, an optical path configuration for the laser printhead. The label modification unit may operate the laser printhead according to the optical path configuration to write the content to the area or erase the content from the area. La présente invention concerne une unité de modification d'étiquette qui peut déterminer, sur la base de la taille de point et du contenu, une configuration de trajet optique pour la tête d'impression laser. L'unité de modification d'étiquette peut faire fonctionner la tête d'impression laser selon la configuration de trajet optique pour écrire le contenu dans la zone ou effacer le contenu de la zone.
