Notes
P =3: specifies the number of parame-
n0
ters (in bytes) to follow
Character Pitch
m=0: unchanged
m=1: Proportional
m>5: m/360 inch
Point size=(n + [n x 256]) x 0.5 point
1 2
Point size can be selected between a
minimum of 8 point to a maximum of
64 point.
Engages/ cancels proportional spacing
n=0 to 255:
n is odd number: start proportional
spacing
n is even number: stop proportional
spacing
When printer is in utility mode, this
command will switch it to LQ propor-
tional until it is canceled.
This is standard pica typewriter size.
Changes to 12 cpi except if Menu item
"SI Select (12 CPI)" is set to "20", then
ESC: will change 17.1 cpi to 20 cpi and
will not change 20 cpi.
OKI unique command. Sets 15 cpi.
Condenses cpi as follows (depending on
MENU setting for SI Select Pitch):
10 cpi: 15 cpi for SI=10; 17.1 cpi for SI=12
12 cpi: 12 cpi for SI=10; 20 cpi for SI=12
15 cpi: 15 cpi for SI=10; 17.1 cpi for SI=12
17.1 cpi: 15 cpi for SI=10; 17.1 cpi for
SI=12
20 cpi: 15 cpi for SI=10;17.1 cpi or 20 cpi
for SI=12
