摘要： An example printhead includes a circulation channel having an inlet for receiving a fluid and an outlet for expelling the fluid, a first nozzle fluidically coupled to the circulation channel, the first nozzle being operable at a first absolute pressure, and a second nozzle fluidically coupled to the circulation channel, the second nozzle being operable at a second absolute pressure, the absolute second pressure being lower than the first absolute pressure. The absolute pressure in the circulation channel decreases as the fluid flows from the inlet to the outlet, and the first nozzle is positioned closer to the inlet of the circulation channel than the second nozzle.

摘要： In some examples, a fluidic die includes an arrangement of fluidic elements to dispense a fluid, where each fluidic element of the fluidic elements includes a fluidic actuator and a fluid chamber. The fluidic die includes an array of fluid feed holes in a plurality of dimensions to communicate the fluid with the fluidic elements, where each of multiple fluid feed holes along a first dimension of the plurality of dimensions is distinct from multiple fluid feed holes along a second dimension of the plurality of dimensions. The fluidic die includes circuit elements interspersed in regions between the fluidic elements along different axes of the fluidic die, where each circuit element of the circuit elements includes an active device. The fluidic elements and the circuit elements are formed on a common substrate.

摘要： Examples include a fluid ejection device. The fluid ejection device includes a fluid ejection die with a die length and a die width, the fluid ejection die being coupled with a support structure having a fluid supply channel therethrough. The fluid ejection die includes a plurality of nozzles arranged in columns at die length positions along the die length and die width positions along the die width such that only one nozzle is positioned at each die length position. A fluid ejection chamber is coupled with each respective nozzle of the plurality of nozzles, and fluid feed hole fluidically coupled with the fluid supply channel and each respective ejection chamber.

摘要： 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.

摘要： A fluid ejection device may include fluid actuators, ejection chambers adjacent the fluid actuators, nozzles extending from the ejection chambers, and fluid feed holes to supply fluid from a fluid supply passage to the ejection chambers. The fluid feed holes have ports connected to the ejection chambers. The ports are sized to pass bubbles formed by the fluid actuators out of the ejection chambers.

摘要： Printheads and methods of fabricating printheads are disclosed. An example printhead includes a substrate and a printhead die disposed on a surface of the substrate, where a top surface of the printhead die projects a first distance from the surface of the substrate. The example printhead also includes a barrier at least partially surrounding the printhead die. A top surface of the barrier projects a second distance from the surface of the substrate, where the first distance is less than the second distance.
