Direct thermal printing is a digital printing process that creates an image directly on a heat-sensitive label material without using a ribbon, ink, or toner. The thermal printhead applies heat directly to the label, which causes a chemical reaction that darkens the material, forming the text and barcodes. This makes direct thermal a simpler and more cost-effective method than thermal transfer printing, as it requires fewer consumables.
It's a popular choice for applications where labels are needed quickly, are not exposed to harsh conditions, and have a relatively short lifespan.
