Abstract
An inkjet printhead assembly includes at least one inkjet printhead including N primitives and an address having M possible address values. Each primitive includes a group of at most M drop generators. The address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time. One drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives. A primitive to address ratio (N/M) of the printhead is at least 10 to 1.
