ESC D n1~nk NULL
[Designation] Set horizontal tab positions
[Format] 1BH, 44H, n1 ~ nk, 00H (k 0)
k bytes
Or 1BH, 44H, 00H (k = 0)
[Valid limits] 0 k 32
1 data 255
[Initial value] Every eight characters where font A (12 × 24) is selected and the right-side
spacing amount of the characters is 0 (character position 9, 17, 25, ...).
[Function] (1) Sets up horizontal tab positions.
(2) Parameter n indicates the left margin or the number of positions from the
beginning of the line to the position setting.
(3) Parameter k indicates the number of horizontal tab position data items to be
set.
(4) The horizontal tab position is set to [n×character width] counted from the
beginning of a line. The character width here includes the space defined by
the Set right-side character spacing (ESC SP). This space is doubled if a double
character width is specified.
(5) Executing this command resets previously set horizontal tab positions.
(6) If n = 8 is specified for horizontal tab positions, executing the Horizontal tab
(HT) command shifts the print position to character position 9.

(7) Up to 32 horizontal tab positions can be set up (k = 32). If k is greater than 32,
the excessive data is processed as ordinary data.
(8) Horizontal tab position (from n1 to nk) must be entered in as sending order and
followed by 00H. If a newly entered data is not larger than the previous data,
the position setting of the horizontal tab is terminated immediately. Also, the
new data is processed as ordinary data.
(9) To reset all horizontal tap positions, use ESC D NULL.
(10) Once the position setting of the horizontal tab is set, changing the character
width does not affect the tab settings.
(11) If the Kanji character mode (FS &) is specified, the horizontal tab
positions are set up in ANK pitch units.
(12) If parameter n exceeds the printable area, the horizontal tab position is set to
the maximum number of print pos 1.
