Inkjet printers has to be refilled with a fresh ink when the ink on that printers are used.You can change the inkjet catridges as well as the ink.Refilling the ink will cost less then changing the catridge.Because catridges contain printer head,roller and ink in them.But the ink is very heap and easy to refill.So almost all people will refill the ink alone until the catridge is very good for their use.If the catridge is not good in its work then they have to replace another catridge which is suitable for their printer. http://www.cheaprefills.info
