• What is the difference between direct thermal and thermal transfer printing?

  Direct thermal printing uses heat-sensitive paper and does not require a ribbon, making it simpler but less durable. Thermal transfer printing uses a ribbon to transfer ink onto the label, offering greater durability and resistance to environmental factors.
