480 BIT-IMAGE GRAPHICS
This command places the printer in 480 Bit Graphics
Mode and identifies which columns are to be reserved
for graphics data. The maximum number of dots per row
in this density is 480 on an 8 inch line.
In the command, n2 represents the number of 'groups' of
\
dot columns to be reserved for graphics data (each group
=
256 single dot columns) and nl is the number of single
dot columns to be reserved for graphics data.
For example, 356 dot columns would be comprised of 1
'group' of 256 and 100 single dot columns, so <nl> would
be 100 and <n2> would be 1. The printer ignores all data
bytes over 480.
Examples:
<ESC> K <224><SOH>
<ESC>K<DEL><SOH>
<ESC> Ka <NUL>
Reserve 480 dot columns.
Reserve 383 dot columns.
Reserve 97 dot columns.
Each byte represents a set of eight dots in a vertical col-
umn. The horizontal position of this column is deter-
mined by its placement within the series of data bytes
(VI
through v
480)'
The vertical position of the dots within this
columnn is determined by the value of the data byte. The
eight dots of the column are a visual representation of the
binary value of the data byte with the lowest value (bit 0)
in the bottom dot position and the highest value (bit
7)
in
the top dot position.
