cartridges

Cartridges are self-contained units used in firearms and some printers. In firearms, a cartridge includes a bullet, propellant (gunpowder), and primer all assembled in a casing, which holds everything together for firing. When triggered, the primer ignites the gunpowder, propelling the bullet forward. In printers, a cartridge contains ink or toner used to produce images or text on paper. Both types are replaceable modules designed for specific devices, ensuring convenience and consistent performance.
