Regarding Claim 8, Takahashi et al. teaches A non-transitory and computer-readable medium storing a program executable by a controller (22, Fig. 8) for a droplet ejecting apparatus (see Fig. 9) [Paragraph 0026 – Description of the Preferred Embodiments], the droplet ejecting apparatus (see Fig. 9) including: a head (600, Figs. 6 and 7) having a nozzle (618, Figs. 6 and 7), a channel (613, Figs. 6 and 7) communicating with the nozzle (618), and an actuator (601, Figs. 6 and 7) configured to apply pressure to a liquid in the channel (613) [Paragraphs 0002-0003]; a driving circuit (21, Fig. 8 ) configured to supply a driving signal to the actuator (601) [Paragraphs 0003-0005 and 0026 – Description of the Preferred Embodiments]; a mover (37/100, Figs. 6 and 8) configured to move the head (600) and a recording medium (700, Fig. 9) relative to each other along a moving direction [Paragraph 0002 and 0026 – Description of the Preferred Embodiments], wherein: the program is configured to cause the controller (22) to execute: causing the mover (37/100) to move the head (600) and the recording medium (700) relative to each other [Paragraphs 0002 and 0026; and causing the driving circuit to supply the driving signal to the actuator to cause the actuator to eject a droplet of the liquid from the nozzle [Paragraph 0003-0005 and 0026 – Description of the Preferred Embodiments]; the driving signal (not shown in Figures) includes a first driving signal (not shown in Figures) configured to cause the actuator (601) to eject the droplet of a first volume, and a second driving signal (not shown in Figures) configured to cause the actuator (601) to eject the droplet of a second volume different from the first volume, a resolution in the moving direction of the second driving signal (not shown in Figures) being higher than a resolution in the moving direction of the first driving signal (not shown in Figures) [Paragraph 0026 – Description of the Preferred Embodiments]; and the program is configured to cause the controller (22) to, in causing the driving circuit (21) to supply the driving signal (not shown in Figures) to the actuator (601) based on one recording instruction, cause the driving circuit (21) to selectively supply the first driving signal (not shown in Figures) or the second driving signal (not shown in Figures) to the actuator (601) [Paragraph 0026 – Description of the Preferred Embodiments]. Allowable Subject Matter Claims 3-6 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: The primary reason for the allowance of claim(s) 3 is the inclusion of the limitation of a droplet ejecting apparatus that includes a first waveform signal includes a first pulse wave causing an actuator to eject a droplet at a first timing , and a second pulse wave amplifying residual vibration in a channel after the first pulse wave. It is these limitations found in the claims, as it is claimed in the combination, that has not been found, taught, or suggested by the prior art of record, which makes these claims allowable over the prior art. The primary reason for the allowance of claim(s) 4 is the inclusion of the limitation of a droplet ejecting apparatus that includes a first and second waveform signal includes one pulse or a plurality of pulse waves, and changing a timing of a width of at least one voltage by the one pulse wave or the plurality of pulse waves of the first waveform signal and changing a timing of a width of at least one voltage by the one pulse wave or the plurality of pulse waves of the second waveform signal. It is these limitations found in the claims, as it is claimed in the combination, that has not been found, taught, or suggested by the prior art of record, which makes these claims allowable over the prior art. The primary reason for the allowance of claim(s) 5 is the inclusion of the limitation of a droplet ejecting apparatus that includes a third waveform signal causing an actuator to ejecting a droplet at both a first and second timing, a controller causing the driving circuit to supply the third waveform signal as a second driving signal, and at least a part of a pulse wave of the third waveform signal is different from obtaining a pulse wave from synthesizing a pulse wave of a first waveform signal and a pulse wave of a second waveform signal. It is these limitations found in the claims, as it is claimed in the combination, that has not been found, taught, or suggested by the prior art of record, which makes these claims allowable over the prior art. The primary reason for the allowance of claim(s) 6 is the inclusion of the limitation of a droplet ejecting apparatus that includes a first channel that flows a liquid of a first color and a second channel that flows a second color different from the first color, and a nozzle includes a first nozzle communicating with the first channel, and second nozzle communicating with the second channel. It is these limitations found in the claims, as it is claimed in the combination, that has not been found, taught, or suggested by the prior art of record, which makes these claims allowable over the prior art.
