Abstract
The present disclosure relates to an inkjet printhead having a plurality of drop generators responsive to drive current and address signals for dispensing ink. The inkjet printhead includes first and second drop generators disposed on the printhead with each of the first and second drop generators configured to receive drive current from a drive current source. Each of the first and second drop generators is configured to receive address signals from a common address source. The inkjet printhead further includes a switching device connected between the common address source and each of the first and second drop generators. The switching device is responsive to enable signals for selectively providing the address signal to only one of the first and second drop generators.
