I’m sure you would have heard from some misinformed people that compatible printer ink cartridges damage printers and don’t print as well as genuine printer cartridges, but this is simply not true. The realism is that compatible Epson D92 ink cartridges on average cost 60% less than the genuine OEM equivalents, and these are not the only ones. Compatible inks for Epson printers offer the biggest savings because of the design of cartridge Epson printers use, they are cheap to manufactures which means third party companies can manufacture them and sell them far cheap than Epson because they have much lower overhead than Epson.
Compatible inks for other brands including HP and Lexmark are slightly different as each cartridge has an integrated print head which makes them expensive to manufacture. Instead of making new ones third party companies recycle OEM cartridges and re-branded as their own instead, this process is known as remanufacturing and is slightly more expensive than manufacturing new compatible Epson ink cartridges but still produces cartridges that offer great savings over the OEM equivalents. Because ink cartridges are consumable items, meaning they are bought many times over by the same people, the third party companies who make compatible ink cartridges rely on consumers buying their products more than once so if their products caused damaged to printer they would go out of business pretty quickly wouldn’t they?
