LK-T21 Technical Manual
[Name] Set line spacing
[Format] ASCII ESC 3 n
Hex 1B 33 n
Decimal 27 51 n
[Range] 0≤n ≤255
[Description] Sets the line spacing to [n x (vertical or horizontal motion unit)] inches.
[Details] ·The line spacing can be set independently in standard mode and in
page mode.
·The horizontal and vertical motion unit is specified by GS P.
Changing the horizontal or vertical motion unit does not affect the current line spacing.
·The GS P command can change the horizontal (and vertical) motion unit.
However, the value cannot be less than the minimum vertical movement amount, and it must
be in even units of the minimum vertical movement amount.
·In standard mode, the vertical motions until (y) is used.
·In page mode, this command function as follows, depending on the
starting position of the printable area :
When the starting position is set to the upper left or lower right to the printable area ①
using ESC T, the vertical motion unit (y) is used.
When the starting position is set to the upper right or lower left of ②
the printable area using ESC T, the horizontal motion unit (x) is used.
·The maximum paper feed amount is 1016 mm {40”}. Even if a paper feed amount of more than
1016 mm{40”}is set, the printer feeds the paper only 1016 mm{40”}
[Default] Line space is equivalent to approximately 4.23 mm{1/6”}.

ESC = n
[Name] Set peripheral device
[Format] ASCII ESC = n
Hex 1B 3D n
Decimal 27 61 n
[Range] 1≤n ≤255
[Description] Selects device to which host computer sends data, using n as follows:
Bit Off/On Hex Decimal Function
Off 00 0 Printer disabled 0
On 01 1 Printer enabled
1-7 - - - Undefined
[Details] ·When the printer is disabled, it ignores all data except for error-recovery
commands (DLE EOT, DLE ENQ, DLE DC4) until it is enabled by this command.
[Default] n=1
ESC ? n
