Sets horizontal tab positions.
♦ n+1 specifies the column number for setting a horizontal tab position from the
beginning of the line.
♦ k indicates the total number of horizontal tab positions to be set.
ƒ
The horizontal tab position is stored as a value of [character width × n] measured from
the beginning of the line. The character width includes the right-side character
spacing, and double-width characters are set with twice the width of normal
characters.
ƒ This command cancels the previous horizontal tab settings.
ƒ Up to 32 tab positions (k = 32) can be set. Data exceeding 32 tab positions is
processed as normal data.
ƒ Transmit [n] k in ascending order and place a NUL code 0 at the end.
ƒ 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.
ƒ ESC D NUL cancels all horizontal tab positions.
ƒ The previously specified horizontal tab positions do not change, even if the character
width changes.
ƒ The character width is independent for each standard and page mode.
When n = 8, printing position is at the ninth line
