About Halftone Types
Your printer provides two different types of halftones—basic and
advanced. These two options allow you to customize the smoothness
of the printed image according to the number of grayscales it uses.

Choices Basic—Regular dot placement at 53 lpi for 300x300 resolution
or 71 dpi for 600x600 resolution.
Advanced—Variable dot placement according to the grayscale
within the image. Generally, this option provides smoother
transitions between grayscales within the image.
