An inkjet printer is a type of computer printer that forms characters and images by propelling droplets of ink onto paper or other substrates. It works on the principle of spraying tiny ink particles through nozzles. These nozzles are precisely controlled, and the ink droplets are ejected in a pattern determined by the digital data it receives from a connected device, such as a computer. Inkjet printers are popular for home and small office use due to their relatively quiet operation, ability to produce high-quality color prints, and affordable price points. They can handle a variety of print jobs, including printing documents, photos, and marketing materials.
