The term 'Type of Cartridge' can refer to two different types of cartridges: TONER (5 letters) and Rimfire (7 letters). TONER is a powder-like substance used in laser printers and photocopiers to create images on paper. It is made up of particles of plastic, carbon, and iron oxide. Rimfire cartridges are a type of ammunition used in firearms. They are made up of a metal case that contains a primer, propellant, and a bullet.
