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 a first respective fluid feed hole fluidically coupled to each respective ejection chamber, and the array of fluid feed holes includes a second respective fluid feed hole fluidically coupled to each respective ejection chamber.

Abstract: Examples include microfluidic devices. Example microfluidic devices comprise a microfluidic channel, a capillary chamber, and a fluidic actuator. The microfluidic channel is fluidly connected to the capillary chamber. The capillary chamber is to restrict flow of fluid therethrough. The fluidic actuator is positioned proximate the capillary chamber. The fluidic actuator is to actuate to thereby initiate flow of fluid through the capillary chamber.
