Printer Inks & Toners and Imaging Supplies are printing equipmets, and are very essential to work. Printers are useless without these supplies. How would you be able to print without ink or toner? If you think that buying lower cost supplies will give you the best value for your money, then you're wrong. It's more practical to buy something a little bit costly but is good in the inside. You know it's worth the price because it lasts longer and works well.
