[Function] Specifies/cancels printing in red
[Code] <1B>H<7E>H<4A>H<n>
[Range] 0≤n≤255
[Outline] Specifies or cancels printing in red.
• Red printing is valid on black-based thermal paper. Specifies or cancels printing in
black
on red-based thermal paper.
• “n” is valid only for the lowest bit (n0).
• Control by the lowest bit (n0) is shown as follows:
n0 Black-based Paper
0 Low density printing (1st color printing)
1 High density printing (2nd color printing)
[Caution] • Valid when 2-color paper is specified by the GS ( E command.
• Valid only when dedicated thermal paper is used.
• This command must not be used for normal thermal paper.
• Conducting pulse amount at low density printing is standard value. At the time of
high density printing, conducting pulse amount is increased to change the coloring.
[Default] n = 0
