Many people have a question: Can Bluetooth thermal printers print in color? There are two concepts here. The first is whether the thermal printer model uses thermal sensing for color or the thermal paper has color content. These are two different concepts.
Generally speaking, thermal printers use thermal transfer technology to heat the coating on thermal paper for printing, and the result is usually black. However, in certain circumstances, thermal paper can also contain colored content, but this is not the color printed by the printer itself.
Thermal paper can print in color, but it usually can only print monochrome labels. With the advancement of technology, new types of thermal label paper have emerged. These papers contain multiple coatings and can produce reactions of different colors under the heating effect of the print head, thus achieving color printing. Although ordinary thermal printers cannot directly print color labels, they can also achieve color effects through special label paper and printing technology.
Thermal printers must use heat-sensitive printing paper. Generally, white thermal paper prints black characters, while red and yellow thermal paper prints blue characters. This is related to the coating on the thermal paper. The color of the coating determines the color of the printed characters.
