Horizontal Positioning Commands
The horizontal positioning commands control the horizontal print positions of

Set Right-Side Character Spacing
Sets the right side character spacing to [n x horizontal or vertical motion units]. Values
for this command are set independently in standard and page mode.
The units of horizontal and vertical motion are specified by the Set Horizontal and
Vertical Minimum Motion Units (GS P) command. Changes in the horizontal or vertical
units do not affect the current right side character spacing. When the horizontal or
vertical motion unit is changed by the Set Horizontal and Vertical Minimum Motion
Units (GS P) command the value must be in even units and not less than the minimum
amount of horizontal movement.
In standard mode the horizontal motion unit is used.
In page mode the horizontal or vertical motion unit differs and depends on the starting
position of the printable area. When the starting printing position is the upper left or
lower right of the printable area (set by Select Print Direction in Page Mode, ESC T) the
horizontal motion unit (x) is used. When the starting printing position is the upper right
or lower left of the printable area (set by Select Print Direction in Page Mode, ESC T) the
vertical motion unit (y) is used.
