Grayscale adjustment settings let you change the Brightness and Contrast of
graphics for monochrome printers. Grayscale adjustment settings are useful if
graphic images are printing too light, too gray, or too dark. Text remains unaffected.

A preview image in the dialog box illustrates any brightness and contrast changes.
Drag the Brightness slider right to lighten, or left to darken the graphic images of the
print job.

right. The brightest setting is +100; the darkest is -100. Zero is the default mid-level
setting. Adjusting brightness is useful when graphic images are printing too dark or
too light. Text remains unaffected.

increase when printed, causing a moiré pattern.
