Description The [ESC] D <n
1
> … <n
k
> NUL command sets the horizontal tab positions. <n>
specifies the column number for setting a horizontal tab position. The command
deletes any previously set, horizontal tab positions. Up to 32 tab positions can
be set. The default tab positions are at intervals of eight characters for 7 x 9 font.

Description The GS L <n
l

h
> command sets the left margin using n
l
and n
h
. The left
margin is set to [(n
l
+ n
h

256)

horizontal motion unit)] from the beginning of
the line. In standard mode, the command is enabled only when input at the
beginning of a line. In page mode, an internal flag is activated, and the
command is enabled when the printer returns to standard mode.

Function Turn ON/OFF Uni-Directional Printing Mode
ASCII [ESC] U <n>
Hexadecimal 1BH 55H <n>
Decimal <27> <85> <n>
Range 0

n

255
Description The [ESC] U <n> command turns on/off unidirectional printing mode. When the
least significant bit (LSB) of <n> = 1, unidirectional printing is turned on. When
LSB = 0, unidirectional printing is turned off, and i-directional printing is turned
on. Unidirectional printing can be turned on when printing double-high
characters to ensure that the top and bottom of the characters are aligned. <n>
= 0 is the default setting.
