Impact cash register carbonless paper is a type of multi-ply carbonless paper specifically designed for dot matrix printers, achieving color development through pressure-sensitive technology. Its core structure consists of the upper ply (CB Layer) and the lower ply (CFB Layer). When the needle of the dot matrix printer strikes the upper ply, the microcapsules rupture and release the color former. The color former reacts with the color developer on the lower ply to produce clear characters, eliminating the need for ribbons or ink. It serves as a crucial supplement to thermal cash register paper in specific scenarios and is widely used in retail, catering, finance, and other fields.
