Abstract
A printhead is provided having elongate printhead modules arranged parallel to each other to extend across a pagewidth and controllers for processing print data into dot data and for controlling the printhead modules in accordance with the dot data. Each printhead module has plural ink ejection nozzles. At least one of the printhead modules is longer than the other printhead modules. The controllers control ink ejection of the nozzles of the printhead modules in accordance with the dot data. At least one of the controllers is arranged to control all of the printhead modules and at least one other of the controllers is arranged to control only one of the printhead modules. Each controller has serial outputs for supplying the dot data for channels of the associated printhead module or modules.
