Description
The horizontal tab position is the character width (when the command was specified)*n from the left
margin.
Enter n values in ascending order and end the settings with NUL.
If an n value is smaller than a previous one, tab setting is ended.
Even if the character width is changed after the horizontal tab positions have been specified, the horizontal
tab position settings do not change.
ESC D NUL cancels all horizontal tab positions.
If the left margin is moved, the horizontal tab positions are also moved by the same amount.
Up to 32 horizontal tab positions can be specified. However, horizontal tab positions beyond the right
margin are invalid and only become valid when a change in the right margin setting or left margin setting
moves the print area to include those tab positions.
The character width when the horizontal tabs are specified includes the settings for the character spacing.
In addition, when a pitch of 10 cpi, 12 cpi or 15 cpi compressed characters or double-width characters are
specified, that character width is considered as the unit.
When proportional pitch is specified with ESC p, horizontal tab positions are specified at 10 cpi.
When the printer is turned on, a horizontal tab position is specified every 8 columns at 10 cpi.
Even if the character width is changed before the horizontal tab positions has been specified, the
horizontal tab positions do not change.
