A compatible inkjet cartridge is a brand new ink cartridge manufactured by a third party for the brand name it is compatible with. In other words, an Epson compatible cartridge isn't manufactured by Epson but by a third party meeting OEM's specifications. What is OEM mean? OEM stands for original equipment manufacturer, in this case, Epson. Compatible ink cartridges provide the same high quality print out and contain the same amount of ink as the OEM inkjet cartridges.
