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.
