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 translation: 描述打印头的喷嘴布局。 在一个示例中，打印头包括具有圆形孔的孔的第一组液滴喷射器，以及具有非圆形孔的孔的第二组喷射器。 处理器接收表示要打印到介质的图像的打印数据，并向打印头提供点火数据以激活液滴喷射器。 点火数据选择具有圆形孔的液滴喷射器以打印图像的图形元素，并且使用非圆形孔选择墨滴喷射器来打印图像的文本元素或线元素。

Abstract: In some examples, a controller receives impedance sensor values from an impedance sensor in a printhead, determines whether the impedance sensor values correlate to a production of an effective drive bubble for the printhead, and issues a command to modify a firing parameter for a fluid ejector of the printhead based on the impedance sensor values.
