Set Horizontal Tabs
ASCII : ESC D [n] k NUL
Hexadecimal : 1B 44 [n] k 00
Decimal: 27 68 [n] k 0
Value of n : Column for tab minus one.
n is always less than or equal to the current selected
column width.
Value of k : 0 - 32
Default: Every 8 characters from column. 1 (9, 17, 25, etc.) for normal
print.
Sets up to 32 horizontal tab positions
n columns from column one, but
does not move the print position. See the Horizontal Tab (09)
command.
The tab positions remain unchanged if the character widths are
changed after the tabs are set. This command ends with hexadecimal
00; hexadecimal 1B 44 00 clears all tabs. Tabs assumed to be in strictly
ascending order. A tab out of order terminates the command string as
if it were 00, and remaining tab values are taken as normal data.
Formulas:
Set the tab positions in ascending order and put Hex 00 at the end.
Hex 1B 44 00 (number of tabs not specified) clears all tab positions.
Exceptions:
The tabs cannot be set higher than the column width of the current
pitch.
