1. Dithering produces an intermediate greyscale by adjusting
the combination of dots used in printing. Selecting a
setting determines the degree of detail with which a
graphics image will be printed. Mesh determines that a
screen of dots is used for dithering while Line Art
determines that an array of lines is used for dithering.
2. Select dithering texture by setting the size of dots used in
the halftone screen.
3. Set this control to print greyscale effects in black without
dithering. Select the check-box to disable greyscale
printing or de-select the check-box to enable greyscale
printing.
4. You can manually adjust lightness (the higher the setting
the lighter the print) and contrast (the higher the setting
the greater the contrast).
5. A single on-screen button restores the default settings.
