Color shade mode (ColorPOS™)
ASCII
GS 0x87 m
Hexadecimal
1D 87 m
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 specifies the shading
effect and has an initial value of 0 which signifies no
effect. m specifies the percentage of shading, 0 <= m <=
100.
m specifies the percentage of shading, 0 <= m <= 100.
If > 0 then monochrome shade mode is turned off as well.
m = 0 is the initial value and turns this mode off.
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 effect 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 defines the relative amount
of black color dots replacing the paper-color ones.
Both text and monochrome graphics are affected by this
command.
Logo print with color plane swap (ColorPOS™)
ASCII
GS 0x89 n m
Hexadecimal
1D 89 n m
Decimal
29 137 n m
This command will print logo n. The command is ignored
if a logo with index n has not been defined. If m = 0 the
color(s) as defined in the logo are used; if m = 1 and if the
logo is a color one, then the two color planes (black and
paper-color) in the logo are swapped.
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 specifies the shading effect and has an initial
value of 0 which signifies no effect.
m specifies the percentage of shading, 0 <= m <= 100.
If > 0 then color shade mode is turned off as well.
m = 0 is the initial value and turns this mode off.
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 effect 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 defines the relative amount of
color dots being “erased” by white originals of the paper.
Both text and monochrome graphics are affected by this
command.
