=0: no movement

Sets left (n) and right (m) margins in 
character columns at current pitch. Once 
set, margins remain fixed even if charac-
ter pitch is changed. m must be at least 
10 character space (at 10 cpi) to the right 
of n.
n=0 to 255; n=0: left margin unchanged
m=0 to 255; m=0: right margin un-
changed

n=1: Unidirectional printing On
n=0: Unidirectional printing Off (return 
to bidirectional)

Prints data in buffer and moves one 
character to the left according to current 
character pitch.

OKI unique command. Sets horizontal 
position of printhead.
