1. Thermal cash register paper
Technical principle: Thermal paper is a single-layer paper with a special chemical coating on the surface. When the laser thermal head is heated, the coating undergoes a chemical reaction and changes color, thus revealing the printed text or image.
Advantages: No carbon ribbon, ribbon or ink cartridge is required, the printing speed is fast and the cost is low.
Technical details: The uniformity of the coating of thermal cash register paper directly affects the printing effect. If the coating is uneven, the printed color will be different in depth. In addition, the chemical formula of the coating determines the storage time of the paper.
2. Double-coated cash register paper
Technical principle: Double-coated paper is a kind of ordinary paper without special coating. It relies on the ribbon to print text on the paper.
Advantages: Suitable for scenes that require carbon copying, such as triplicate or quadruple copies.
Technical details: The quality of double-coated cash register paper depends on the folding resistance and printing clarity of the paper. High-quality paper can withstand repeated folding and friction, and the printed text is clear and readable.
3. Carbonless cash register paper
Technical principle: Carbonless paper uses microcapsule technology to achieve the carbon copying function. When the print head pressure acts on the first copy, the microcapsules break and release ink or toner, making the following copies colorable.
Advantages: clear writing, not easy to fade, suitable for long-term storage.
Technical details: Carbonless cash register paper is usually composed of two or more layers, and the copying effect between each layer depends on the distribution of microcapsules and the pressure of the print head.
4. Environmentally friendly cash register paper
Technical principle: Environmentally friendly cash register paper is made of degradable or recycled materials to reduce the impact on the environment.
Advantages: Meet environmental standards and reduce pollution.
Technical details: The manufacturing process of environmentally friendly cash register paper requires strict control of the source and treatment of materials to ensure that it meets environmental requirements.
