Abstract
An inkjet printing system having multiple independent power supplies for providing firing energy to the ink ejection elements of one or more printheads. Different ones of the power supplies can be connected to different print cartridges each of which prints a different color ink; to different arrays of ink ejection elements within a single print cartridge, where each array prints a different color ink; or to different sections of the ink ejection element array of a single printhead for a single color ink. The output of each power supply is independently set to an appropriate voltage level for each different print cartridge, ink ejection element array, or section of an array.
