ESC Q Specify right margin

Decimal: 27 81 n
Hexadecimal: 1B 51 n
Parameters
1≤n≤255
Left margin
Description
 The left margin and the right margin use the left edge of the physically printable area as the reference.
 The right 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.
 Left margin≤print area
 The position of the right margin is the character width (when the command was specified)*n from the left
edge.
The character width when the margin is specified includes the settings for the character spacing, full-width
character spacing or half-width character spacing. In addition, when a pitch of 10 cpi (=20 dots) or 12 cpi
(=16 dots), compressed characters or double-width characters are specified, that character width is
considered as the unit.
However, character styles that increase the character width are not applied.
 The horizontal print position is moved to the left margin position.
 If the right margin setting is not at the beginning of the line, the right margin is specified 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 right margin has been specified, the right margin position
does not change.
 A right margin setting that puts the right margin position to the left of the left margin position is ignored.
 The right margin should be specified at least one column (10 cpi=20 dots) greater than the left margin.
(If the character width (when the command was specified)*n is less than the left margin+20 dots, the
setting is 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 (=20 dot) is
applied.
 If the print media is continuous length tape, the printing orientation is landscape and the page length is not
specified, commands specifying the right margin are ignored.
