  • Patent number: 10160210
    Abstract: In an example, a non-transitory processor-readable medium stores code representing instructions that when executed by a processor cause a printing system to determine a text and line print mode or a graphics print mode to use for printing upcoming image content. The printing system selects a first nozzle column to print the image content when the text and line print mode is determined, and selects a second nozzle column to print the image content when the graphics print mode is determined.
