Just wanted to say that Samsung makes it extremely difficult to use off-brand toner cartridges. They put a chip on the cartridge and on the printer and if you buy an off-brand cartridge, it will tell you that it does not recognize the toner cartridge you installed. There is a work around with it and if you are handy with computers, you can Google it and get around it, but if you are a novice, you either need to buy the higher priced Samsung cartridges or buy a different printer. Brother printers will allow you to use off-brand cartridge.
