Abstract: In some examples, a fluid ejection die includes a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner, wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die, wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns that are spaced by a first distance across the width. The plurality of nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

Abstract: Examples include a fluid ejection die having a die length and a die width. The fluid ejection die may include a plurality of nozzles arranged along the die length and a die width. The plurality of nozzles is arranged such that at least one pair of neighboring nozzles are positioned at different die width positions along the width of the fluid ejection die. The example fluid ejection die further includes a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle. The fluid ejection die further includes an array of fluid feed holes. The array of fluid feed holes includes at least one fluid feed hole fluidically each respective ejection chamber.

Abstract: A fluid ejection device includes a fluid ejection die to eject drops of fluid and a body to support the fluid ejection die, with the fluid ejection die including a fluid ejection chamber, a drop ejecting element within the fluid ejection chamber, and a fluid feed hole communicated with the fluid ejection chamber, and with the body including a fluid feed slot communicated with the fluid feed hole of the fluid ejection die. The fluid ejection device includes a micro-recirculation system to recirculate fluid within the fluid ejection die through the fluid ejection chamber, and a macro-recirculation system to recirculate fluid within the body through the fluid feed slot across the fluid feed hole of the fluid ejection die.
