This command switches the settings for the following commands (in which the
values can be set independently in standard mode and page mode) to those for
standard mode:
①Set right-side character spacing: ESC SP, FS S
②Select default line spacing: ESC 2, ESC 3
The following commands are enabled only to set in standard mode.
①Set printing area in page mode: ESC W
②Select print direction in page mode: ESC T
The following commands are ignored in standard mode.
①Set absolute vertical print position in page mode: GS $
②Set relative vertical print position in page mode: GS \
Standard mode is selected automatically when power is turned on, the printer is
reset, or command ESC @ is used.

Decimal 27 84 n

17
[Range] 0 n3
48 n51
[Description] Selects the print direction and starting position in page mode.
n specifies the print direction and starting position as follows:
n Print Direction Starting Position
0, 48 Left to right Upper left
1, 49 Bottom to top Lower left
2, 50 Right to left Lower right
3, 51 Top to bottom Upper right
[Details] When the command is input in standard mode, the printer executes only
internal flag operation. This command does not affect printing in standard
mode.
This command sets the position where data is buffered within the printing area
set by ESC W.
Parameters for horizontal or vertical motion units ( x or y) differ as follows,
depending on the starting position of the printing area:
①If the starting position is the upper left or lower right of the printing area, data
is buffered in the direction perpendicular to the paper feed direction:
Commands using horizontal motion units: ESC SP,ESC $,ESC \
Commands using vertical motion units: ESC 3,ESC J,GS $,GS \
②If the starting position is the upper right or lower left of the printing area, data
is buffered in the paper feed direction:
Commands using horizontal motion units: ESC 3,ESC J,GS $,GS \
Commands using vertical motion units: ESC SP,ESC $,ESC \

Hex 1B 56 n
Decimal 27 86 n

18
[Range] 0 n1, 48 n49
[Description] Turns 90clockwise rotation mode on/off
n is used as follows:
n Function
0, 48 Turns off 90clockwise rotation mode
1, 49 Turns on 90clockwise rotation mode
[Details] This command affects printing in standard mode. However, the setting is
always effective.
When underline mode is turned on, the printer does not underline 90
clockwise-rotated.
Double-width and double-height commands in 90rotation mode enlarge
characters in the opposite directions from double-height and double- width
commands in normal mode.

31. ESC W xLxHyLyHdxLdxHdyLdyH(*)
[Name] Set printing area in page mode
[Format] ASC II ESC W xL xH yL yH dxL dxH dyL dyH
Hex 1B 57 xL xH yL yH dxL dxH dyL dyH
Decimal 27 87 xL xH yL yH dxL dxH dyL dyH
[Range] 0 xL, xH, yL, yH, dxL, dxH, dyL, dyH 255 (except dxL= dxH=0 or dyL= dyH=0)
[Description] The horizontal starting position, vertical starting position, printing area width,
and printing area height are defined as x0, y0, dx (inch), dy (inch), respectively.
Each setting for the printing area is calculated as follows:
x0 = [( xL + xH 256) (horizontal motion unit)]
y0 = [( yL + yH 256) (vertical motion unit)]
dx = [ dxL + dxH 256] (horizontal motion unit)]
dy = [ dyL + dyH 256] (vertical motion unit)]
The printing area is set as shown in the figure below.
[Details] If this command is input in standard mode, the printer executes only internal
flag operation. This command does not affect printing in standard mode.
If the horizontal or vertical starting position is set outside the printable area, the
printer stops command processing and processes the following data as normal
data.
If the printing area width or height is set to 0, the printer stops command
processing and processes the following data as normal data.
This command sets the position where data is buffered to the position specified
by ESC T within the printing area.
If (horizontal starting position + printing area width) exceeds the printable area,
the printing area width is automatically set to (horizontal printable area -
horizontal starting position).
If (vertical starting position + printing area height) exceeds the printable area,
the printing area height is automatically set to (vertical printable area - vertical
starting position).

The horizontal and vertical motion unit are specified by GS P. Changing the
horizontal or vertical motion unit does not affect the current printing area.
The GS P command can change the horizontal (and vertical) motion unit.
However, the value cannot be less than the minimum horizontal movement
amount, and it must be in even units of minimum horizontal movement amount.
Use the horizontal motion unit ( x) for setting the horizontal starting position and
printing area width, and use the vertical motion unit ( y) for setting the vertical
starting position and printing area height.
When the horizontal starting position , vertical starting position, printing area
width, and printing area height are defined as X, Y, Dx, and Dy respectively, the
printing area is set as shown in the figure below.
This printable area for this printer is approximately 73 mm in the horizontal
direction and approximately 150mm in the vertical direction.
[Default] xL = xH = yL = yH = 0
dxL = 72, dxH = 2, dyL = 176, dyH = 4

Hex 1B 5C nL nH
Decimal 27 92 nL nH
[Range] 0 ≤nL ≤255
0≤nH ≤255
[Description] Sets the print starting position based on the current position by using the
horizontal or vertical motion unit.
•This command sets the distance from the current position to [( nL + nH ╳ 256) ╳
horizontal or vertical motion unit]
[Details] •Any setting that exceeds the printable area is ignored.
•When pitch N is specified to the right:
nL+ nH ╳ 256 = N
