Thermal printers need heat-sensitive paper because the main component of this type of printer is heat. The roll of paper is placed in a container that is part of the machine with the end of the roll fed into a slot. Pigments form letters and pictures on the paper as the paper reacts to the heat of the printer head.
These are some of the top brands for thermal printers: Hewlett-Packard, Zebra, Tektronix and ALPS MicroDry Printers.
The printing speed process of this printer makes the ink dry very quickly and this is what makes the printer work so well. Basic thermal printers move at speeds from 6 to 12 inches per second. Thermal fax machines work the same way but on a much larger scale.
These printers use barcode printing and label printing. Thermal printers are among the least expensive printers. In addition the process of printing made by this printer is relatively quiet. These printers are often used on calculators and very-low-priced computers. However, they require special paper that may discolor in time.
