A drive signal is generated having at least one pulsed curvilinear waveform shape. This drive signal is applied to a fluid dispenser to cause fluid ejection. Additionally, a drive signal is generated having one or more non-sinusoidal curvilinear waveform shapes. This drive signal is applied to a fluid dispenser to cause fluid ejection. Still further, a drive signal is generated having multiple segments including at least one segment having a curvilinear waveform shape. This drive signal is applied to a fluid dispenser to cause fluid ejection.
