A method and an apparatus to control a temperature of a printer head chip. The temperature control apparatus includes a heater, a temperature sensor, and a controller. The heater heats a predetermine portion of the printer head chip. The temperature sensor senses the temperature of the printer head chip. The controller is provided in the printer head chip and provides a control signal to the heater according to the sensed temperature. Accordingly, damage to the printer head chip can be prevented and safety in using the printer can be guaranteed. Also, ink droplets can be accurately ejected from the printer head chip such that printing quality is improved and a life span of the heater is extended.
