How a billing machine Works?
The Bill printing machines work on a process called Thermal printing. It is a digital printing process which produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image. Two-color direct thermal printers can print both black and an additional color (often red) by applying heat at two different temperatures. The technology is quite old but ideal for bill printing machines. Bill printers print by direct contact between the thermal head (which generates heat) and thermal paper (which is thermally coated to be sensitive to heat). The paper rolls available are sensitive to the heat and thus when the heat is produced it can easily initiate the process of printing. It can print more tha...
