  • Maintaining a print quality parameter in a printer
    Patent number: 11407221
    Abstract: A printer includes a print head to print a pixel by ejecting drops of a printing fluid from the print head, and a controller. The controller monitors a drop volume of the printing fluid ejected by the print head. When the drop volume is below a threshold, the controller controls the print head in accordance with a first print mode to increase the frequency of ejecting drops of the printing fluid within the pixel print time with a decrease in the drop volume that maintains a print quality parameter. The controller changes to a second print mode to increase the pixel print time that maintains the print quality parameter.
