ESC D n1... nk NUL
[Name] Set horizontal tab positions
[Format] ASCII ESC D n1...nk NUL
Hex 1B 44 n1...nk 00
Decimal 27 68 n1...nk 0
[Range] 1 ≤ n ≤ 255
0 ≤ k ≤ 32
[Description] Sets horizontal tab positions.
• n specifies the column number (counted from the beginning of the line) for setting a horizontal
tab position.
• k indicates the total number of horizontal tab positions to be set.
[Details] • The tab position is set at [character width x n] from the beginning of the line. The character
width includes the right-side space of the character, and is twice the normal value when
double-width is specified.
• This command deletes horizontal tab positions that have already been set.
• When "n = 8" has been set for the horizontal tab position, the printing position moves to the
ninth digit when HT is executed.
• Up to 32 tab positions can be set. Data exceeding 32 tab positions is processed as normal
data.
• Input <n>k in ascending order and place a NUL code <00>H at the end. When <n>k is less
than or equal to the preceding value <n>k-1, tab setting is finished and the following data is
processed as normal data.
• ESC D NUL cancels all horizontal tab positions.
• The previously specified horizontal tab positions do not change, even if the character width
changes.
[Default] The default tab positions are at intervals of 8 characters (columns 9, 17, 25, ...) for font B (7 ×
9).
