    • A method to determine an amount of remaining fluid in a replaceable fluid supply unit includes determining a first estimated fluid volume of a first replaceable fluid supply unit in communication with a fluid ejector unit, determining a first correction factor corresponding to the first replaceable fluid supply unit in communication with the fluid ejector unit including at least a first volume ratio parameter corresponding to a ratio of a first nominal fluid volume of the first replaceable fluid supply unit and the first estimated fluid volume, determining an amount of fluid consumed from a second replaceable fluid supply unit configured to replace the first replaceable fluid supply unit, and determining a remaining amount of fluid in the second replaceable fluid supply unit by subtracting the determined amount of fluid consumed from a second nominal fluid volume of the second replaceable fluid supply unit.

    • For each totally black pixel of image data to be printed using a fluid-ejection printing device, it is determined whether the pixel is part of a line feature or an area fill feature of the image data. Where the pixel is part of a line feature, a first printing mask selected that is optimized for printing line features. Where the pixel is part of an area fill feature, a second printing mask is selected that is optimized for printing area fill features. Each mask specifies a number of fluid droplets to be printed and positions where the fluid droplets are to be printed. The selected mask is applied to the pixel. The pixel is printed using the mask that has been applied. The fluid-ejection printing device prints the pixel by ejecting the number of fluid droplets specified by the mask at the positions specified by the mask.
    • 对于使用流体喷射打印装置要打印的图像数据的每个全黑色像素,确定像素是图像数据的线特征或区域填充特征的一部分。 在像素是线要素的一部分的情况下,选择针对打印线特征进行优化的第一打印掩模。 在像素是区域填充特征的一部分的情况下,选择针对打印区域填充特征而优化的第二打印掩模。 每个掩模指定要打印的多个液滴和要液体液滴被打印的位置。 所选择的掩码应用于像素。 使用已应用的掩码打印像素。 流体喷射打印装置通过在由掩模指定的位置处喷射由掩模指定的流体液滴的数量来打印像素。
