Claim 8:
9. A method of driving an inkjet head configured to eject a solvent-based glass ink from a nozzle which connects to a pressure chamber by changing a volume of the pressure chamber using an actuator, the method comprising, before performing printing:
outputting, to the actuator for a first time period, a first signal for changing the volume of the pressure chamber such that the ink forms a meniscus in the nozzle without being ejected from the nozzle;
after outputting the first signal, outputting, to the actuator for a second time period, a second signal for changing the volume of the pressure chamber for ejecting the ink from the nozzle, wherein the second time period is a time period required for the ink that has formed the meniscus to be ejected from the nozzle; and
after outputting the second signal, outputting, to the actuator for a third time period, a third signal for changing the volume of the pressure chamber without ejecting the ink from the nozzle, wherein
a length of each of the first and third time periods is determined based on a half of a characteristic vibration period of the ink and a particular coefficient.
