Reverse Color Text Mode (Colorpos ® ) - CognitiveTPG A799 Programming Manual

Revision D 12/09
Turns on white/black reverse print mode. In white/black reverse print mode, print dots and non-print dots are reversed,
which means that white characters are printed on a black background. When the white/black reverse print mode is selected
it is also applied to character spacing which is set by right-side character spacing (1B 20).
This command can be used with built-in characters and user-defined characters, but does not affect the space between
lines.
White/black reverse print mode does not affect bit image, downloaded bit image, bar code, HRI characters, and spacing
skipped by horizontal tab (09), set absolute starting position (1B 24 ...), and set relative print position (1B 5C).
White/black reverse print mode has a higher priority than underline mode. When underline mode is on and white/black
reverse print mode is selected, underline mode is disabled, but not canceled.
Bar codes, logos, and bit images are not affected by this command.
Exceptions
Only the lowest bit of n is valid.

If the current color is not black and two-color paper is loaded, no visible effect takes place.
In A793 emulation, the command is unrecognized and the parameter byte is put into the print buffer.
Set smoothing
ASCII
GS b n
Hexadecimal
1D 62 n
Decimal 29 98 n
Value of n: 0 = smoothing off,
1 = smooting on,
default = off
Turns smoothing mode on or off for the quadruple or larger sizes of characters.
Reverse color text mode (ColorPOS
ASCII GS 0x85 m n
Hexadecimal 1D 85 m n
Decimal 29 133 m n
Value of m:
0 = white
1 = black
2 = paper color
Value of n:
0 = white
1 = black
2 = paper color
Default:
m = 0 (off )
Sets a mode for reverse printing effects on text. The background color is specified by m, while the text color is specified by
n. Setting m = 0 turns off the mode.
If m = n but not zero, the printer produces solid printing in the given color. This tactic can be used to minimize the
firmware busy work.
The value of current color and white/black reserve print mode is superceded by the value of n whenever this mode is on
(m>0).
Bar codes, logos, and bit images are not affected by this command.
