! Images printed with the GW controller may show a "halo" effect
when printing in 2-bit mode (1800x600dpi) and in 4-bit mode
(9600x600dpi).
" This problem is most visible when text is overlaid onto halftone
areas. The greater the difference in image density between text
and halftone areas, the more noticeable the halo effect.
" This problem is also evident when the mode is changed to 2-bit
mode. (The default dithering pattern for 2-bit mode is designed to
improve gradation, but this can also make the halo effect more
visible.)
