Driver circuit for a printhead

A method comprising:

• controlling a printhead with a jetting controller, wherein the printhead comprises a plurality of jetting channels with nozzles of the jetting channels aligned in a row along a length of the printhead, wherein a first subset of two or more consecutive jetting channels in the row is configured to jet a first print fluid, and a second subset of two or more consecutive jetting channels in the row is configured to jet a second print fluid;
• the controlling comprising:
• generating a drive waveform comprising a plurality of print-fluid-specific jetting pulses provisioned for different print fluids, wherein the print-fluid-specific jetting pulses include first print-fluid-specific jetting pulses provisioned for jetting the first print fluid, and second print-fluid-specific jetting pulses provisioned for jetting the second print fluid, and wherein the first print-fluid-specific jetting pulses and the second print-fluid-specific jetting pulses are not shared between the different print fluids;
• and
• designating gating signals for jetting the first print fluid and the second print fluid;
• receiving the drive waveform and the gating signals at the printhead from the jetting controller;
• selectively applying the first print-fluid-specific jetting pulses from the drive waveform to actuators of the first subset based on the gating signals to jet the first print fluid from the first subset;
• and
• selectively applying the second print-fluid-specific jetting pulses from the drive waveform to the actuators of the second subset based on the gating signals to jet the second print fluid from the second subset.

A jetting system, comprising:

• a printhead comprising a plurality of jetting channels with nozzles of the jetting channels aligned in a first row along a length of the printhead, wherein a first subset of two or more consecutive jetting channels in the first row is configured to jet a first print fluid, and a second subset of two or more consecutive jetting channels in the first row is configured to jet a second print fluid;
• and
• a jetting controller that includes at least one processor configured to:
• generate a drive waveform comprising a plurality of print-fluid-specific jetting pulses provisioned for different print fluids, wherein the print-fluid-specific jetting pulses include first print-fluid-specific jetting pulses provisioned for jetting the first print fluid, and second print-fluid-specific jetting pulses provisioned for jetting the second print fluid, and wherein the first print-fluid-specific jetting pulses and the second print-fluid-specific jetting pulses are not shared between the different print fluids;
• and
• designate gating signals for jetting the first print fluid and the second print fluid;
• the printhead further comprising:
• a driver circuit configured to receive the drive waveform and the gating signals from the jetting controller, selectively apply the first print-fluid-specific jetting pulses from the drive waveform to actuators of the first subset based on the gating signals to jet the first print fluid from the first subset, and selectively apply the second print-fluid-specific jetting pulses from the drive waveform to the actuators of the second subset based on the gating signals to jet the second print fluid from the second subset.
