Merge watermark mode (ColorPOS ® )
ASCII GS Ox8C n m
Hexadecimal 1D 8C n m
Decimal
29 140 n m
Default 0 (off)
This command will insert the logo m as a repeated
background image, similar to printing a visible watermark,
into the print stream. The space between repetitions of this
usually shaded logo will be every n*8 dot rows.
n >0 = number of dot rows x8 to skip before repeating the
merge action
m specifies the index value of the logo. If no logo has been
defined with this index then the command is ignored.
Note: Horizontal placement of a watermark logo was
fixed at the time the logo was Shaded or when it was
downloaded as a full width logo for watermark use. This
command will be ignored if the current logo is not at full
paper width size (see the apply shading to logo command
for preparing logos for watermark use).
The merge process is performed after all other image
formation and takes whatever print raster data is ready to
be put on paper. It “adds” (computer logic OR) the mono
or color bits to the print row. Generally, if the print dot was
to be white or same color as the watermark dot, the print
dot will be the color of the watermark; otherwise it will be
black.
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.
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.
Turning monochrome shade mode on, turns color shade
mode off.
