Compatible ink is a product marketed by someone other than the printer manufacturer, therefore it is a newly manufactured product and can not be exactly the same as the original so as not to violate any industrial property law. Its reliability will depend on the manufacturer and / or distributor. The remanufactured ink is an original ink in which a re-fabrication process has taken place, that is, the casing has been used, but everything inside it is new. Being a refabricated product does not violate the law of industrial property since it has not been manufactured, it has only been manipulated, and its reliability depends on who and how to do the process and the guarantees give us who the product is sold to us.
The refilled ink is an original ink that once again has been refilled with ink, but all its elements are old, therefore, it offers little reliability.
