Abstract
A fluid-ejection printhead die includes first fluid-ejection nozzles, second fluid-ejection nozzles, and a mixing barrier. The first fluid-ejection nozzles eject fluid of a first type, and are organized over a first row and a second row non-collinear to the first row. The second fluid-ejection nozzles eject fluid of a second type different than the first type, and are organized over a third row and a fourth row non-collinear to the third row. The fourth row is at least substantially collinear to the first row. The mixing barrier is at least substantially between the first row of the first fluid-ejection nozzles and the fourth row of the second fluid-ejection nozzles.
