• Prints dot graphics in raster format (row by row, left
to right)
• Allows compression of graphics data during raster
graphics printing; counters can be included with data
to specify the number of times to repeat a particular
byte of data
• Parameters are used as described below:
c = 0 Full graphics mode (noncompressed)
1 Compressed raster graphics (Run Length
Encoding) mode
v Vertical resolution in dpi
- 720, 360, 180 (3600/v dpi)
h Horizontal resolution in dpi
- 720, 360, 180 (3600/h dpi)
m Vertical dot count (rows of dot graphics)
nL, nH Horizontal dot count (columns of dot
graphics), according to the following formula:
nH = INT(horizontal dot count)/256
nL = MOD(horizontal dot count)/256
k Total number of data bytes, according to the
following formula:
k = mX INT((nHX256)+nL + 7)/8)
d During full graphics mode:
Graphics data
During RLE compressed raster graphics mode (ESC . 1):
The first data byte is treated as a counter. Graphics data
bytes then alternate with a data counter byte (run-length
data compression), as follows:
0 ≤ (counter byte) ≤ 127
Counter specifies the number of data bytes following
according to the formula below.
(counter byte) + 1 = (number of data bytes to follow)
or
(counter byte) = (number of data bytes to follow) – 1
128 ≤ (counter byte) ≤ 255
