Thermal printing is a digital printing process in which coated thermochromic paper is selectively heated while passing over the thermal print head, and the coating turns black in areas where it’s heated thus generating your printed images. Dual colour direct thermal printers achieve black as well as one additional colour by applying heat on the thermochromic paper at two different temperatures.


Thermal transfer printing utilizes a heat sensitive ribbon instead of paper and apart from this is similar to thermal printing.

When compared to dot matrix printers, thermal printers are a lot more ideal for portable and retail applications as they make less sound, work faster, consume less power and are relatively less bulky.

They are also required for commercial applications as filling station pumps, voucher printers in slot machines, information kiosks, point of scale systems, print on demand labels and also for recording live rhythm on hospital cardiac monitors.
