Horizontal direction movement commands
ESC l Specify left margin
[ASCII] ESC l n
[Decimal] 27 108 n
[Hexadecimal] 1B 6C n
[Parameters] 0 ≤ n ≤ 255
0 ≤ left margin < right margin
[Description]
・ The left margin and the right margin use the left edge of the physically printable area as
the reference.
・ The space between the left edge of the physically printable area and the set number of
columns is set as an unprinted area. The left margin position is the right edge of the
specified column. (Character width * n)
・ The setting is in the range 0 ≤ (character width * n) ≤ x. Settings outside that range are
ignored. However, x is a value dependent on the media.
・ The area between the left edge (first column) to the nth column is specified as an
unprinted area.

・ The position of the left margin is the character width * n (at the time that the left margin is
set) from the left edge.
The character width when specifying the margin includes the settings for specifying
character spacing, character spacing for full-width characters or half-width characters. In
addition, when pitches of 10 cpi (= 30 dots), 12 cpi (= 25 dots), or 15 cpi (= 20 dots),
reduced characters, or double-width characters are specified, that character width is
considered the unit.
However, increases in the character width due to character styles are not applied.
