A ribbon cartridge is a key component used in dot matrix printers, typewriters, and some calculators to transfer ink onto paper. It consists of a fabric ribbon, typically made of nylon, which is coated with ink and housed in a plastic casing. As the printer's print head strikes the ribbon, ink is imprinted onto the paper, producing text or images. Ribbon cartridges are durable and can handle continuous, high-volume printing, making them ideal for environments that need consistent output, such as banking, retail, or industrial settings. They are cost-effective and provide reliable performance for printing documents, receipts, or multi-copy forms. Though less common today, they remain valuable for specific applications requiring robust, low-maintenance printing solutions.
