摘要：An ink jet printing device supplies first and second signals to cause a pressure
generating chamber to jet out ink droplets. A third signal is applied to the pressuregenerating chamber to effectively attenuate the kinetic energy of the meniscus and tohold the meniscus at a position suitable for jetting out the next ink droplet to provide astable print output. Also, an ink-jet recording apparatus is provided with a control meansfor controlling the timing of the start of the second signal and the timing of the start ofthe third signal according to the environmental temperature. In the ink-jet recordingapparatus, the discharge speed of ink drops is made constant by regulating the starttime of the second signal so as to make constant the drawing position of a meniscuswhen the ink drops are discharged. Further, the pressure generating chamber isexpanded again by applying the third signal at the time the vibration of the meniscusgenerated by the discharge of the ink drops is moved closest to the pressure generatingchamber, so that the kinetic energy of the meniscus moving to the nozzle can effectivelybe attenuated.
