Control of laser printhead for writing or erasing content

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.

2. The method of claim 1 , wherein the content is associated with an image depicted by one or more pixels, and

wherein the size of the area is based on the one or more pixels in the area and a size of the label.

3. The method of claim 1 , further comprising:

determining the size of the area based on a quantity of pixels in an image associated with the content;

determining a size of the label; and

determining the size of the area based on the size of the label and the quantity of pixels.

4. The method of claim 1 , wherein the spot size of the light beam is configured to be relatively smaller to perform a write operation associated with the size of the area and relatively larger to perform an erase operation associated with the size of the area.

5. The method of claim 1 , wherein determining the optical path configuration comprises:

determining, based on the spot size and the content, a power level of the light beam to write or erase the content in the area; and

generating the optical path configuration according to the power level.

6. The method of claim 1 , wherein the optical path configuration includes information that identifies at least one of:

a duration of time associated with operating the one laser printhead to emit the light beam on the area, and

a movement rate for operating the single laser to emit the light beam between portions of the area.

7. The method of claim 1 , wherein, when the label modification indicates a write operation associated with the content and the area, the optical path configuration is configured to cause the one laser printhead to heat the area to a writing temperature and cool the area at a writing rate,

wherein the writing temperature is warmer than an erasing temperature for an erase operation associated with the label and the writing rate is faster than an erasing rate for the erase operation.

8. The method of claim 1 , wherein, when the label modification indicates an erase operation associated with the content and the area, the optical path configuration is configured to cause the one laser printhead to heat the area of the label to an erasing temperature and cool the area at an erasing rate,

wherein the erasing temperature is cooler than a writing temperature for a write operation associated with the label and the erasing rate is slower than a writing rate for the write operation.

9. A device, comprising:

a memory; and

a processor communicatively coupled to the memory configured to:

receive an input associated with modifying content in an area of a label;

determine, based on a size of the area, a spot size of a light beam that is configured to be emitted by a single laser of one laser printhead to modify the content within the area;

determine, based on the spot size and the content, a laser configuration for the single laser; and

operate the single laser according to the laser configuration to modify the content in the area, wherein

the content is modifiable by utilizing the one laser printhead to write the content to at least a portion of the area or erase the content from at least a portion of the area.

10. The device of claim 9 , wherein the content includes a monochromatic pattern of one or more pixels in the area.

11. The device of claim 9 , wherein the processor, when determining the spot size, is configured to:

determine a label modification associated with the content being written to the area or erased from the area; and

determine the spot size based on the label modification.

12. The device of claim 9 , wherein the laser configuration identifies, based on the spot size, at least one of:

a duration of time associated with operating the single laser to emit the light beam over the area,

a movement rate operating the single laser to emit the light beam over the area, and

a power level associated with the single laser emitting the light beam over the area.

13. The device of claim 9 , wherein the processor, when operating the single laser, is configured to control modifying a dimension of the content based on at least one of:

controlling a power level of the light beam,

controlling a configuration of an optical element to focus the light beam or adjust the spot size, and

controlling a position of a reflector to cause the light beam to be directed over the area at a particular movement rate.

14. The device of claim 9 , wherein the label is a rewritable label.
