A recording control method and a recording apparatus in which high accuracy in the position of a discharged liquid droplet is obtained irrespective of changes in the temperature of a recording head are provided. In a liquid discharging method in which a bubble is generated by supplying ink (a liquid) with thermal energy, and the generated bubble is caused to communicate with the atmospheric air, by controlling a driving signal so that a discharging state in which a part of the ink to be discharged falls even if the temperature of the recording head changes, the direction of ink discharge can be stabilized.
A liquid-discharge control method, in which a bubble is generated by supplying a liquid with thermal energy by driving one of electrothermal transducers, and the liquid is displaced and discharged from a corresponding one of nozzles by causing the bubble to communicate with the atmospheric air, said method comprising:
A liquid discharging apparatus comprising a head, which comprises electrothermal transducers, each for generating a bubble by supplying a liquid with thermal energy, and nozzles for discharging the liquid, for causing the bubble to displace and discharge the liquid by causing the generated bubble to communicate with the atmospheric air, said apparatus comprising:
