Original ink cartridges are produced by the original manufacturer (e.g. Canon, Epson, HP, Lexmark).
Eco-cartridges or Remanufactured ink cartridges are recycled original cartridges, thus reducing environmental side effects from ink cartridges as a “consumable”. The cartridge has been cleaned professionally, refilled and tested by a third party and not by the original manufacturer. These cartridges are much cheaper compared to the price of an original cartridge since the cartridge is recycled.
Compatible cartridges will work just as good for your inkjet printer but are not produced by the original manufacturer. The upside is that they are sold at a considerable lower price than original ink cartridges.
Independent tests have confirmed the quality of compatible cartridges compared to original cartridges and the fact that a consumer will save a lot of money by using alternatives to original ink cartridges.
