They are small plastic or metal cartridges that contain the ink or toner for your printer. The cartridge contains a sponge-like material that absorbs the ink and transfers it to the page, as well as a print head that delivers the ink to the page. Ink cartridges can be refilled or replaced with new ones. Inkjet printers come with different types of ink cartridges: black, photo, and color. Black ink is the most common type used in home and office printers because it can print text documents in high definition and quality without straining your eyesight. Photo ink allows you to print out high-quality photos with vivid colors and textures. Photo-grade printers have separate photo-quality ink cartridges but they may not be compatible with other types of printers
