Quality
Selecting Custom in the Print Quality allows you to adjust the print quality level.
Dragging the slider to the right enhances the print quality while dragging the slider to the left increases
the printing speed.
Black and White Photo Print
Set black and white photo printing. Black and white photo printing refers to the function of converting your
document to grayscale data in the printer to print it in monochrome.
When you check the check box, both monochrome and color documents will be printed in monochrome.
When printing a color document, be sure to uncheck the check box.
