How to Use the Direct Print Function
[Halftones] This setting specifies how you print halftones.
Halftoning is used to print each process color at a different
intensity, allowing millions of different color to be reproduced
using only the four process colors.
Depending on the required intensity of a given color, toner is
placed on paper in dots of different sizes. The grid of dots
used for each toner color is called a screen. Halftone screens
are aligned to unique angles designed to eliminate interference
patterns called moiré (a shimmering, wavy effect) that can
arise with halftoning.
• If [Resolution] is selected, a dither pattern that gives priority
to the resolution of the images is used. This helps eliminate the
appearance of jagged or uneven lines along the edges of
objects and is best for printing standard text and graphics.
• If [Gradation] is selected, a dither pattern that gives priority to
the appearance of smooth changes in tone is used. This is best
for reproducing images with delicate gradations or changes of
tone.
• If [Error Diffusion] is selected, an error diffusion method that
gives priority to printing fine lines or text is used. This is best for
printing images with small text or very fine lines.

Smoothing]
This setting smooths jagged outlines of graphics (illustrations
created by application software) and characters.
[Smooth 2] performs a higher level of smoothing than [Smooth
1]. If [Smooth 1] is selected and the results are still not printed
smoothly, select [Smooth 2].
By enabling the 'Graphics' and 'Text' options, you can select
whether to apply smoothing to graphics or text data.
