    摘要: A printhead is provided having elongate printhead modules arranged to aggregately 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 rows of ink ejection nozzles. The nozzle rows of at least one of the printhead modules are longer than the nozzle rows of 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.

    摘要: A printer includes a printhead having first and second elongate printhead modules; and first and second printer controllers receiving print data and processing the print data to output dot data to the printhead, the first printer controller outputting dot data to the first printhead module and the second printer controller outputting dot data to the second printhead module. The first elongate printhead module is informationally isolated from the second elongate printhead module, whereby no dot data passes therebetween. The first printer controller and the second printer controller communicate therebetween a synchronization signal to effect synchronization therebetween.

    摘要: 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.
