Abstract

Examples include a fluid ejection device. The fluid ejection device includes at least one fluid ejection die coupled to a support structure and having a die length and a die width. The at least one 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 at least one fluid ejection die further includes a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle. The at least one 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 coupled to each respective ejection chamber.
