What is the difference between direct thermal and thermal transfer printing? There are two thermal printing methods: direct thermal and thermal transfer. Each method uses a thermal printhead that applies heat to the surface being marked. Thermal transfer printing uses a heated ribbon to produce durable, long-lasting images on a wide variety of materials.
