ABSTRACT:
An ink-jet printhead accepts a series of digital addresses as image data. Each digital address causes an individual ejector in the printhead having the particular address to be activated. The frequency of operation of the printhead can be directly related to the frequency at which addresses are submitted to the printhead. A scheduler polls image data for spot placements which require simultaneous activation of a plurality of ejectors in a set of interdependent ejectors, and then reschedules the activation of ejectors to avoid conflicts.
