Description
➊
This code sequence sets unidirectional printing mode only for one line. The printing is
carried out from left to right.
➋
This code sequence sets or resets unidirectional printing mode. Unidirectional printing
is enabled when 1 is specified for n and is disabled when 0 is specified.
In text mode, printing is faster when unidirectional printing is disabled. However, char-
acters on one line may be slightly shifted with respect to those in the preceding line
when bidirectional printing is used.
In its default setting the printer is set to bidirectional printing.
