Ribbon is a special material used for printing in devices such as computer printers. It is made up of a ribbon and hundreds of thousands of small carbon balls covered on it. When printing, the ribbon comes into contact with the paper in accordance with the pattern, and the carbon balls release carbon ink that covers the paper to form the text or pattern. Ribbon is suitable for both black and white and colour printers, and prints more clearly and with greater durability than common ink cartridges and toner cartridges.

Ribbon is also a printing material for thermal printers. Thermal printers are printers that use a thermal print head to heat a specific area during printing, which transfers the dye on it to the print media. Each time a print is made, the ribbon forms a layer of toner between the thermal print head and the media, the print head heats up on it at a specified location, and the toner melts onto the media to form text and patterns. The use of ribbons in thermal printers is characterised by low cost and low noise and is suitable for offices and homes.

In addition to being used in printers, ribbons can also be used in a number of specialised areas. For example, in the field of industrial automation, ribbons are often used for logo printing and barcode printing. The high definition and long colour development of ribbons make them a reliable printing medium. In addition, ribbons are used as measuring tools in construction and underground engineering, where they are used to record measurements by attaching them to the surface of various construction materials. The wide range of applications makes ribbon a powerful and indispensable printing material.
