Abstract: A print head die may include a substrate, an electrical connector and at least three liquid feed slots. The electrical connector is on a first side of the substrate and extends along the major dimension of the substrate. The electrical connector is connectable directly to an electrical interconnect to connect the print head die to a controller. The at least three liquid feed slots are formed in the substrate and extend along the major dimension of the substrate. Wherein at least one and less than all of the at least three liquid feed slots has an associated temperature sensor connected to the electrical connector.

Abstract: A fluid dispenser is disclosed herein. An example of such a fluid dispenser includes a member configured to define a plurality of orifices through which a fluid is ejected and a manifold including a plurality of fluid passageways each of which is configured to have a different angle relative to the member. This example of a fluid dispenser additionally includes a plurality of slots each of which is coupled to a different one of the fluid passageways of the manifold to conduct the fluid from the fluid passageways towards the orifices. Additional features and modifications of this fluid dispenser are disclosed herein, as are other examples of fluid dispensers.

Abstract: 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.

Abstract: 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.

Abstract: 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.
