Canon BJ-200e - Manual (Page 44)

Options
As part of your printer setup, you can specify certain options that
control the half-toning and intensity of your printed graphics and text.
From this screen you can select Halftone options and an Intensity level:
T Click on the drop-down arrow next to the Halftone setting to
select one of the following:
Pattern, which is the default
Diffusion
Pattern is available for Print Selections of Black and White and
Grayscale. Diffusion is available for Grayscale only.
Pattern uniformly aligns individual dots to produce shades of gray;
this method offers fast printing speed. Diffusion randomly places
individual dots; this method produces subtle gradations and is best
suited for printing documents that contain finely detailed graphics
or photographic images. (The Diffusion setting may help eliminate
banding problems when printing grays or all black images.)
T You can control the intensity with which text and graphics are
printed using the Intensity setting. This controls the threshold at
which a pixel value is turned on or off. Setting the scroll bar to the
left results in darker print and setting it to the right results in
lighter print. The default is the value represented at the center of
the scroll bar. (In some applications, setting the scroll bar all the
way to the right causes nothing to print.
