Abstract
An ink container includes an ink chamber for storing ink, a print head installed below the ink chamber for receiving ink from the ink chamber, an ink channel installed between the ink chamber and the print head for passing ink from the ink chamber to the print head, a nozzle installed below the print head for injecting ink, and a heater installed beside the nozzle for heating ink so as to inject ink through the nozzle. The resistive layer of the heater has essentially refractory material, oxygen and nitrogen.
