Abstract: A fluid ejection device includes a fluid slot, three laterally adjacent fluid ejection chambers each having a drop ejecting element therein, a fluid circulation path communicated with each of the three laterally adjacent fluid ejection chambers, and a fluid circulating element within the fluid circulation path, with at least two laterally adjacent fluid ejection chambers of the three laterally adjacent fluid ejection chambers to substantially simultaneously eject drops of fluid therefrom such that the drops of fluid are to coalesce during flight.
