• Threshold, for black-and-white printing, lets you determine which
colors are printed as white, and which
as
black. You change the
Threshold setting by dragging the arrow
in
the slider below the label
Threshold. When the setting for Image
is
Positive and the Threshold
setting
is
2, only the darkest color on the display
is
printed
as
black,
while the rest
is
white. Increasing the value
of
the Threshold setting
causes more colors to be printed
as
black. As you increase the
setting, the lighter colors are printed
as
black.
When the setting for Image
is
Negative, the higher the Threshold
setting, the lighter are the colors that are printed
as
black.
Note that not all these choices apply to all printers. For example, letter-quality
printers that use a
"daisy
wheel"
printhead can only produce one quality
of
printing. To find out what selections apply to your printer, see the documentation
provided with the printer.
When you're done making selections for your printer, select OK to confirm your
selections or Cancel to cancel them. Selecting either OK or Cancel returns you to
the Change Printer Screen.
