1. A method, comprising:
receiving, by a device, an input that indicates a label modification associated with writing content to a label or erasing content from the label, the device utilizing one laser printhead having a single laser to write the content to the label or erase the content from the label;
identifying, by the device, an area of the label that is associated with the label modification according to the input;
determining, by the device and based on a size of the area, a spot size of a light beam that is configured to be emitted by the single laser of the one laser printhead to modify the content within the area;
determining, by the device and based on the spot size and the content, an optical path configuration for the one laser printhead; and
operating, by the device, the one laser printhead according to the optical path configuration to write the content to the area or erase the content from the area.
