    Abstract: A label modification unit may receive a label modification input associated with an image. The label modification unit may obtain a bitmap associated with a modification to the rewriteable label. The label modification unit may determine, based on the bitmap and using a heat dissipation model, temperature profiles for a plurality of raster print paths of the laser. The label modification unit may select, based on the temperature profiles and from the plurality of raster print paths, a raster print path for the modification. The label modification unit may control at least one of the laser, the optic, and the reflector system to: cause the light beam to follow the raster print path, and emit the light beam according to an array of power factors that are associated with the raster print path.

    Abstract: A label modification unit may receive a label modification input associated with an image. The label modification unit may process, using an image filtering, the label modification input to convert the image to a bitmap for raster printing the image via a laser printhead. The label modification unit may determine, based on the bitmap, an array of power factors for a light beam that is configured to be emitted by a laser of the laser printhead and raster print the image. The label modification unit may control the laser of the laser printhead in association with raster printing the image on a rewriteable label according to the array of power factors.

    Abstract: 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.
