Abstract: In one example in accordance with the present disclosure a printhead is described. The printhead includes a number of nozzles to deposit an amount of fluid onto a print medium and an ink delivery system to deliver the amount of fluid from an ink tank to the number of nozzles. The printhead also includes an attachment feature to removably couple a removable printhead cover to the printhead. The printhead further includes a removable printhead cover removably coupled to the printhead at the attachment feature.

Abstract: Staggered fluid ejection dies may include first, second and third fluid ejection dies, each of the dies having fluid feed passages between first and second long edges. And electrical interconnect may extend from a location proximate the first long edge of each of the fluid ejection dies. A temperature sensor may be supported proximate the second long edge of each of the fluid ejection dies. Each of the fluid ejection dies may omit temperature sensors proximate the first long edge.

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: Various configurations of print head die are described. In an example, a first print head die has first print structures disposed along a major dimension thereof perpendicular to the media path, the first print structures including a leading print structure with respect to the media path. A second print head die independent of the first print head die has second print structures disposed along a major dimension thereof perpendicular to the media path, the second print head die being staggered with respect to the first print head die along the media path, the second print structures including a leading print structure with respect to the media path. A portion of the second print structures overlap a portion of the first print structures by an extent between a minimum value and a linear function of a separation between the respective leading print structures of the first and second print head dies.
