For
improved
print
quality,
1920
bit-image
graphics
prints
at
half
the
speed
of
480
bit-image
graphics
(ESC
K).
The
printer
can
print
1920
dot
columns
on
an
8-inch
line,
at
254 mm (10
in.)
per
second.
If
you
specify
adjoining
dot
positions,
the
second
dot
does
not
print.
You
can
mix
bit
image
data
with
text
data
on
the
same
line.
n
2
,
v
1
,
v
2
,
and
v
19
20
represent
the
same
values
as
in
480
bit-image
graphics
(ESC K).
The
total
number
of
bit-image
data
bytes
is
equal
to
n
1
+
(n
2
x 256)
and
cannot
exceed
1920
(the
total
number
of
dot
positions
in
an
8-inch line).
For
example
,
to
print
1920
dot
columns,
n
1
=
128
and
n
2
=
7.
Refer
to
the
description
of
ESC

for
a
complete
description
of
the
values
.
