In
inkjet printing, a compatible cartridge refers to an ink
cartridge that is not manufactured by the original manufacturer of your
printer (called an
OEM cartridge), but will function and work in the same way that an OEM cartridge would. Many printer manufacturers will state that using any compatible cartridge in your printer will void the warranty. However, compatible cartridges are popular with consumers because of the lower cost to purchase, compared to an OEM cartridge.
