ESC "D" n1 n2 NUL
[Function] Setting the horizontal tab position
[Code] <1B>H <44>H n1 n2 <00>H
[Range] 1 ≤ n ≤ Max. print columns – 1
1 ≤ k ≤ 16
[Outline] This command sets the horizontal tab positions. n indicates the number of lines from the
head of the line to the horizontal tab setting position. k indicates the number of horizontal
tab positions to be set.
The tab position is set at the character width × n from the head of the line. The character
width at this time includes the right space of the character and will be doubled if the double
width characters are specified.
The data <n>k indicating the set position is entered in the ascending order and ends with
<00>H. ESC D NUL clears all the set tab positions. After clearing the tab positions, HT will
be ignored.
[Caution] If the data <n>k is equal to or smaller than the preceding data <n>k - 1, it is assumed that
horizontal tab setting has been completed. In that case, the subsequent data will be processed
as regular one.
Up to 16 tab positions can be set. If the data exceeds this limit, it will be processed as regular
data. If the data <n>k exceeds the one-line print range, the set column position will equal the
maximum print columns + 1.
If the character width is changed after setting the horizontal tab positions, they will not
change.
