Rev. 0.70
ESC GS A n1 n2
[Name] Specify absolute position
[Code] ASCII ESC GS A n1 n2
Hexadecimal 1B 1D 41 n1 n2
Decimal 27 29 65 n1 n2
[Defined Area] 0 ≤ n1 ≤ 255
0 ≤ n2 ≤ 255
[Initial Value] ---
[Function] Moves the printing position to the (n1 + n2 x 256) position based on the left margin.
The right margin is also the reference for upside-down printing.
This command is ignored if the print region is exceeded.
When print data is duplicated, the new print data is overwritten by the old print data. (the portion duplicated in
the new data is deleted.) However, bit image data is OR processed for the old print data.
ESC GS R n1 n2
[Name] Specify relative position
[Code] ASCII ESC GS R n1 n2
Hexadecimal 1B 1D 52 n1 n2
Decimal 27 29 82 n1 n2
[Defined Area] 0 ≤ n1 ≤ 255
0 ≤ n2 ≤ 255
[Initial Value] ---
[Function] Moves the printing position from the current position to the (n1 + n2 x 256) position.
This command is ignored if the print region is exceeded.
When (n1 + n2 x 256) ≥ 32768, it moves {65536 – (n1 + n2 x 256)} dots in the left direction.
When (n1 + n2 x 256) < 32768, it moves (n1 + n2 x 256)} dots in the right direction.
When print data is duplicated, the new print data is overwritten by the old print data. (the portion duplicated in
the new data is deleted.) However, bit image data is OR processed for the old print data.
