Claim 0:
1. An inkjet head for printing using a solvent-based glass ink, comprising:
a pressure chamber in which the ink is to be stored;
a nozzle plate including a nozzle which connects to the pressure chamber;
an actuator configured to change a volume of the pressure chamber; and
a drive circuit configured to, before printing is performed:
output a first signal to the actuator for a first time period 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, output a second signal to the actuator for a second time period for changing the volume of the pressure chamber such that the ink is ejected 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, output a third signal to the actuator for a third time period 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.
