Monochrome shade mode (ColorPOS
®
)
ASCII GS 0x86 m
Hexadecimal 1D 86 m
Decimal 29 134 m
This applies a selected shade density to all monochrome objects such as text and monochrome logos. The parameter
m species the shading eect and has an initial value of 0 which signies no eect.
m species the percentage of shading, 0 <= m <= 100.
m = 0 is the initial value and turns this mode o.
Note: that only a few gradations will be perceptible, so large increments of m, such as 20, should be used. If a reverse print
mode is on, the shade eect will be applied to the background only.
When the current color mode is set to black, increasing values of m relate to the relative amount of (white) paper that
replaces black dots. Analogously, when the paper-color is the current color, m denes the relative amount of color dots
being “erased” by white originals of the paper.
Both text and monochrome graphics are aected by this command.
Turning monochrome shade mode on, turns color shade mode o.

Decimal 29 135 m
This applies a mixing of color into any monochrome objects such as text and monochrome logos. Rather than fading
away, this mode transitions a character or logo from the current color in which it would normally be printed to the
other color. The parameter m species the shading eect and has an initial value of 0 which signies no eect. m
species the percentage of shading, 0 <= m <= 100.
m species the percentage of shading, 0 <= m <= 100.
m = 0 is the initial value and turns this mode o.
Note: Only a few gradations will be perceptible, so large increments of m, such as 20, should be used. If a reverse print mode
is on, the shade eect will be applied to the background only.
When the current color mode is set to black, increasing values of m relate to the relative amount of paper-color that
replaces black dots. Analogously, when the paper-color is the current color, m denes the relative amount of black
color dots replacing the paper-color ones.
Both text and monochrome graphics are aected by this command.
Turning color shade mode on, turns monochrome shade mode o.
