DATA
Sets resolution for raster image print.
LCNT
values specify the low count of
the total number of data bytes and the
five parameter bytes which follow the
LCNT
and
HCNT
parameters.
HCNT
values specify the high count of the
total number of data bytes and the five
parameter bytes which follow the
LCNT
and
HCNT
parameters.
FLAGS
values of
X'801F00' for multicolor image mode
(the default) or X'100300' for dual color
image mode can be used.
HR
and
VR
values are dots per inch resolution
horizontally and vertically. This
printer supports 100 horizontally and 96
or 72 vertically.
Note: The interpretation of the
DATA
parameter in the
CR1
control code
depends upon the format established by
the
FLAG
bytes. For multicolor image,
DATA
represents the information to
print one horizontal scan line. Each
scan line consists of three data blocks
and each data block describes the three
colors to be printed across the complete
scan line. The first "n" bytes of
DATA
address "n x 8" print dots across the
scan line with a one bit meaning to
print the color red, and a zero bit
meaning not to print red. The next "n"
bytes of
DATA
address the same "n x 8"
