A dot matrix printer is a type of printer that produces text and images by striking an ink-soaked ribbon against paper using a series of tiny pins. These pins create dots, which combine to form characters and graphics. This technology allows for multi-part forms, making it useful in business settings where carbon copies are needed. Dot matrix printers are known for their durability and ability to print on various types of media, including labels and envelopes. While they are less common today due to the rise of inkjet and laser printers, they are still used in specific applications where low-cost printing and continuous forms are required.
