OEM (Original Equipment Manufacturer) Cartridges refers to the cartridges which are manufactured and marketed by printer manufacturer viz. HP, Samsung, Canon, Epson, etc. in their brand.
Compatible Cartridges are cartridges manufactured & marketed by a company (other than OEM) to suit & work on the printers made by other companies HP, Samsung, Canon, Epson, etc.
Remanufactured- Some manufacturers collect used (empty) cartridges, clean and refill and market them as remanufactured cartridges in their own brand. Remanufacturing of toner cartridges may also require replacement of some worn out components, viz. blades, OPC drums, PCRs etc.
OEM cartridges – Made by the manufacturer of the original printer. Fit best, and typically have the highest quality ink, but also cost the most.
Compatible cartridges – made by a 3rd party company, but designed to fit and work in the same model printer. Typically much cheaper than the OEM cartridges. Quality is generally pretty close, but some generic cartridges may not fit as well, might not be as UV resistant, and aren’t quite a perfect match to the OEM tints. No part of these is made by the original company. They’re entirely cloned cartridges, including the lock chips. Some do not include the lock chips, and require that you salvage the chips off your old cartridges.
Remanufactured cartridges — They only do this with the cartridges that have a built in print head. The remanufactured cartridges salvage the OEM cartridge hulls that some companies have you send in for recycling. The cartridges are opened, cleaned, and have the flow control batting swapped out.
The ones sold under the OEM branding will be refilled with the same ink as the new OEM ones (HP and Lexmark offer remanufactured cartridges as well as new). These should perform identically to the new OEM cartridges, but cost 1/2 or 1/3 less than the new ones. Lexmark claims the new ones have sharper printing for text and pictures, but I doubt anyone could tell the difference without a microscope.
The ones sold under 3rd party branding will be refilled with some other inks, and should be considered the same as “compatible” cartridges in terms of performance and price — they just fit better, as the hulls are from old OEM cartridges.
OEM Cartridge – An OEM Cartridge is one made by the Original Equipment Manufacturer. If you own a Hewlett-Packard Laserjet printer for instance, then the Hewlett-Packard brand is the OEM cartridge for your printer.
Remanufactured Toner Cartridge – A remanufactured toner cartridge is when a manufacturer takes an original oem cartridge, disassembles it, tests and replaces any worn parts, fills it with toner and re-assembles.
Compatible Toner Cartridge – A compatible toner cartridge is made by a third party manufacturer and is made up of all new compatible parts. It has a similar quality to an OEM cartridge.
OEM (Original Equipment Manufacturer) Laser Printer Cartridges refers to the cartridges which are manufactured and marketed by printer manufacturer viz. HP, Samsung, Canon, Epson, etc. in their brand.
Compatible Laser Printer Cartridges are cartridges manufactured & marketed by a company (other than OEM, say ProDot) to suit & work on the printers made by other companies HP, Samsung, Canon, Epson, etc.
OEM stands for original equipments and compatible means it is perfect for other equipments.
