Abstract: Nozzle layouts for printheads are described. In an example, a printhead includes a first set of drop ejectors having orifices with circular bores, and a second set of drop ejectors having orifices with non-circular bores. A processor receives printing data representing an image to be printed to media, and provides firing data to the printhead for activating the drop ejectors. The firing data selects the drop ejectors with the circular bores to print graphic elements of the image and selecting the drop ejectors with the non-circular bores to print textual elements or line elements of the image.

Abstract: A print head (24, 224, 424, 624) includes a layer (36, 236) which at least partially forms firing chambers (42, 242) and ribs (46, 246, 646) in contact with opposing side walls of a fluid feed slot (40, 240) while extending from a first side wall to a second opposite side wall within the fluid feed slot (40, 240).

Abstract: A printhead assembly is provided, the printhead assembly including a printhead die, a black fluid slot formed in the printhead die to deliver black printing fluid, and a color fluid slot formed in the printhead die to deliver color printing fluid.

Abstract: The described embodiments relate to slotted substrates. One exemplary method forms a feature into a substrate, at least in part, by directing a laser beam at the substrate. During at least a portion of said directing, the method supplies a conductive material proximate the substrate.

Abstract: A method of manufacturing a fluid ejection device. A plurality of drive transistors is disposed on a substrate, the drive transistors each comprising contacts. A metal layer is disposed over the contacts. The plurality of drive transistors includes a primitive group of drive transistors, and the metal layer includes a power buss covering each of the contacts of the primitive group of drive transistors.

Abstract: Processing a die that has an edge and a substrate upon which a layer of moisture permeable material is disposed. The moisture permeable material extends to the edge of the die. One embodiment comprises interrupting the layer of moisture permeable material to form a gap at a boundary near the edge, thereby to substantially block movement of moisture through the gap of the moisture permeable material.

Abstract: A fluid ejection device includes a first heater element and a second heater element spaced a first distance from the first heater element. A first drive transistor is associated with the first heater element and a second drive transistor is associated with the second firing heater element. The second drive transistor is spaced a second distance from the first drive transistor. The second distance is different from the first distance.
