Brother TD-4100N - Manual (Page 43)

・ The horizontal direction print position is moved to the left margin position.
・ If the left margin setting is not at the beginning of the line, the left margin is set after a line
feed.
The beginning of the line indicates the left margin position for left alignment; for right and
center alignment, it means that no image or character is entered on the line.
・ Even if the character width is changed after the left margin is set, the left margin position
does not change.
・ Any left margin setting that puts the left margin position to the right of the right margin
position is ignored.
・ When setting the left margin, set it at least one column (10 cpi = 30 dots) smaller than the
right margin.
[(the character width * n at the setting) > (number of dots of right margin - 30 dots) -->
the setting will be ignored.]
・ If the difference between the right margin position and the left margin position is less than
one character, that character is ignored.
・ When proportional pitch is specified with the ESC p command, a character width of 10
cpi (= 30 dot) is applied.
・ If the print media is continuous length label, the print direction is landscape, and the page
length is not specified, commands specifying the left margin are ignored.
[Example] The left margin is set to Column 3.
