Notes
Move to the left, relative to present posi-
tion, calculated as
(n =[n x 256])/ 120 inches
1 2
n =0 to 255
1
n =0 to 255
2
n =n =0: no movement
1 2
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.
