What is the deal with using non oem ink for printers? Is it harmful to printers? I hate to spend a fortune on genuine ink when when I can get non oem for so much cheaper. I have a Brother J825DW and I can get a 10 pack of black and color for $14. If I were to buy a 10 pack of genuine Brother ink, I would probably be spending $100 or more. I really don't need a 10 pack, just used that as an example. I don't print that much. Sorry if this has been asked before.
