affected by changing the horizontal spacing. The physical position of the tab stop depends on the
horizontal spacing in operation when ESC D is used. The ESC D 0 cancels all active tab stops.

This code sets the left margin at the current horizontal spacing. It must be sent at the beginning of the
line. The n parameter specifies the number of columns. For each type of horizontal spacing there is a
different range of possible values, as shown in the following table:
Character Width Horizontal Spacing Range of columns
Double Width 5 0 ≤ n ≤ 67
6 cpi 0 ≤ n ≤ 80
7.5 cpi 0 ≤ n ≤ 100
8.5 cpi 0 ≤ n ≤ 114
10 cpi 0 ≤ n ≤ 134
