Sets/cancels unidirectional printing.
(1) Unidirectional printing (n=l or 49)
When ESC U (1)0 or ESC U (49)0 is input, all data following this
code will be printed only when the print head is moving
unidirectionally from left to right. Unidirectional printing is
effective to further improve the precision of vertical character
alignment.
(2) Bidirectional printing (n=O or 48)
When the ESC U (0)0 or ESC U (48)0 code is input, the
unidirectional print mode is cancelled and the printer returns to
the normal bidirectional print mode.
