Understanding Thermal Printers
A thermal printer is a printing device that uses heat to produce text, graphics, barcodes, and other information on compatible materials. Unlike conventional inkjet and laser printers, thermal printing technology does not depend on traditional ink cartridges or toner.
The printer uses a thermal printhead containing small heating elements. These elements activate specific areas of the printing material to create the required image.
Thermal printers generally operate through two main technologies: direct thermal printing and thermal transfer printing. Both use heat, but their printing materials and applications differ.
Direct thermal printers create images on specially coated heat-sensitive paper, while thermal transfer printers use a heated ribbon to transfer ink onto labels or other surfaces.
1. Direct Thermal Printers
