Compatible vs. Remanufactured vs. Original

Original (OEM) supplies are new from the printer brand and cost the most. Compatible supplies, like this one, are newly manufactured by a third party to the original's size and page-yield specifications, so they drop into the same slot at a much lower price. Remanufactured supplies are emptied originals that have been cleaned and refilled.
