Decimal 27 85 n
[Defined Area] Thermal : -
Slip : 0 ≤ n ≤ 2, 48 ≤ n ≤ 50, (“0” ≤ n ≤ “2”)
Validation : 0 ≤ n ≤ 2, 48 ≤ n ≤ 50, (“0” ≤ n ≤ “2”)
[Initial Value] Thermal : -
Slip : n = 0
Validation : n = 0
[Function]
Only setting is valid
Setting is valid after switching to slip or validation.
,
Executes print direction specified by this command after printing data in the line buffer.
n State Transition
0, 48 Specify bi-directional printing
1, 49 Specify uni-directional printing
Bi-directional printing is faster than uni-directional printing.
With uni-directional printing, printing is performed only when the print head moves from left to right.
The printing direction can be set independently for both line mode and page mode.
Setting values are shared for slip, and validation line mode and page mode is selected.
