Set Horizontal Tab Positions
ASCII | ESC D [n]…k NUL |
Hexadecimal | 1B 44 [n]…k 00 |
Decimal | 27 68 [n]…k 0 |
Value of n: | Column number for tab minus one. |
| (n is always less than or equal to the current selected column width) |
Value of k: | |
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 command (09).
The tab positions remain unchanged if the character widths are changed after the tabs are set. The 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:
Standard pitch = | 44 columns |
Compressed pitch = | 56 columns |
