Printhead having rows of symmetrically arranged nozzles

A printhead comprising a plurality of rows of print nozzles, each print nozzle being defined as a unit cell having first and second drive circuitry for that print nozzle respectively positioned at separate regions of that print nozzle with an ejection nozzle therebetween,

• wherein the unit cells in each row are rotated 180 degrees relative to the respective positions of the unit cells in each adjacent row such that for a first row and a second row which are adjacent one another the respective first circuitry are adjacent each other and for the second row and a third row which are adjacent one another the respective second circuitry are adjacent each other, and
• wherein the first drive circuitry of a cell unit is a control logic for controlling whether and when the cell unit ejects ink, and the second drive circuitry of the cell unit is a drive transistor circuit for providing electric current to an actuator of the cell unit that ejects ink when enabled by the control logic.
