Abstract
A fluid ejection assembly includes at least one inner layer having a fluid passage defined therein, and first and second outer layers positioned on opposite sides of the at least one inner layer. The first and second outer layers each have a side adjacent the at least one inner layer and include drop ejecting elements formed on the side and fluid pathways communicated with the drop ejecting elements. The fluid pathways of the first and second outer layers communicate with the fluid passage of the at least one inner layer, and the at least one inner layer and the fluid pathways of the first outer layer form a first row of nozzles, and the at least one inner layer and the fluid pathways of the second outer layer form a second row of nozzles.
