摘要： An ink drop let jetting method and an apparatus are provided to easily and arbitrarily control a volume of ink droplets without changing the voltage value of a jet pulse. Thus, printing with a desired resolution may be achieved. When the volume of ink droplets (or printing density) is increased, the printing frequency of a timing period of the jet pulse is set to a reciprocal of an even-numbered multiple of the time T in which a pressure wave propagates within an ink chamber in one-way. Also, when the volume of ink droplets is decreased, the printing frequency is set to a reciprocal of an odd-numbered multiple of the time T in which a pressure wave propagates within an ink chamber in one-way. Alternatively, printing is executed at intermediate frequencies. According to this method, it becomes possible to print dots with an arbitrary resolution.

摘要： When a print data reception circuit 2 receives a print command, the print data reception circuit 2 transmits data indicating this to a drive signal generating circuit 6, and also transmits data indicating a desired member of ejections per dot to a drive signal correction circuit 8. Based on memory content of a reference data storage circuit 4, the drive signal generating circuit 6 produces a reference drive signal, which includes a predetermined maximum number of ejection pulses for printing each single dot, and transmits it to the drive signal correction circuit 8. The drive signal correction circuit 8 produces a print drive signal by removing unnecessary ejection pulses from the reference drive signal, in accordance with the desired number of ejection pulses indicated in the print command, and than transmits the print drive signal to a charge/discharge circuit 10. The charge/discharge circuit 10 controls electric potential difference between electrodes 619, 921 in accordance with high and low levels of the application drive signal. The piezoelectric material between the electrodes 619 and 621 deforms according to the electric potential difference, so that a desired number of ink droplets are ejected.
