Notes
Prints a continuous overscore over all
text characters except for tab spaces.
n=0 to 255
n=odd: start overscore
n=even: stop overscore
Dot density 60 dpi horizontal, 72 dpi
vertical.
Maximum data per line: ML390 Tur-
bo=480: ML391 Turbo=816
l,h=0 to 255: specifies amount of subse-
quent Bit Image bytes received, calculat-
ed as l + (h x 256).
Dot density 120 dpi horizontal, 72 dpi
vertical.
Maximum data per line: ML390 Tur-
bo=960: ML391 Turbo=1632
l, h=0 to 255: specifies amount of subse-
quent Bit Image bytes received,
calculated as l + (h x256).
Same as low speed double density (120
dpi), but printer can't put two adjacent
dots in the same row.
Dot density 240 dpi horizontal, 72 dpi
vertical. Printer can't put two adjacent
dots in the same row.
Maximum data per line: ML390 Tur-
bo=1920: ML391 Turbo=3264
l,h=0 to 255: specifies amount of subse-
quent Bit Image bytes received,
calculated as l + (h x 256).
In PPR emulation, sets ratio of vertical to
horizontal dot density in bit image
graphics. Valid only for ESC K, ESC L,
