High volume pagewidth printing

摘要

A print assembly (14) for pagewidth inkjet printing that includes an elongate carrier that is mountable on a support structure (12) of a printer (10) in an operative position with respect to a platen (106, 108) of the printer. A number of printhead chips (186) are positioned on the carrier. The print head chips together define a print head that is configured to eject at least one billion drops per second into a printing zone defined between the print head and the platen of the printer. Control circuitry is also positioned on the carrier and is configured to control operation of the print head chips.
