[Description]
Turns on or off white/black reverse printing mode.
When the LSB of
n
i
s 0, white/black reverse mode is turned off.
When the LSB of
n
is 1, white/black reverse mode is turned on.
[Notes]
●
Only the lowest bit of
n
is valid.
●
When white/black reverse printing mode is on, it also applied to character spacing set
by
ESC SP
.
●
This command does not affect bit image, user-defined bit image, bar code and HRI
characters.
●
This command does not affect the space between lines.
●
White/black reverse mode has a higher priority than underline mode. Even if
underline mode is on, it is disabled (but not cancelled) when white/black reverse
mode is selected.

[Notes]
This command can be used when the power supply does not give the current request
(less speed
less average current), or when an accurate outline quality is desirable
(less speed
best outline quality).

[Description]
Selects the print position of HRI characters when printing a bar code.
n
selects the print position as follows:
n
Printing position
<00>H / <30>H
Not printed
<01>H / <31>H
Above the bar code
<02>H / <32>H
Below the bar code
<03>H / <33>H
Both above and below the code bar
[Notes]
●
HRI indicates Human Readable Interpretation
●
HRI characters are printed using X-scale = 1, Y-scale = 1 and the font specified by
GS f
.
