Title: Printhead integrated circuit with more than 10000 nozzles

Abstract: A printhead integrated circuit having a monolithic wafer substrate supporting an array of droplet ejectors for ejecting drops of printing fluid onto print media. Each drop ejector has a nozzle and an actuator for ejecting a drop of printing fluid through the nozzle. The array has more than 10000 of the droplet ejectors so that it provides a high nozzle pitch and the printhead has a very high `true` print resolution--i.e. the high number of dots per inch is achieved by a high number of nozzles per inch.
