[Range of Definition]
r = 00H, 01H, 02H, 04H,11H,12H
c = 00H, 01H
b = 01H, 02H
0000H <= (nH*256 + nL) <= 7FFFH
0001H <= (mH*256 + mL) <= 7FFFH
[Function]
1) Prints dot graphics in raster format.
2) Parameters are used as described below:
r :
c :
b :
nL, nH: Horizontal byte count, according to the following formula:
mL, mH: Vertical dot count ( rows of dot graphics ), according to the following formula:
k :
** Sample bits of data for 4 pixels of an image using 2 bits data/pixel:
The size of the dot is designated with a binary number, using 2 bits for every 1 picture element.
No Dot: 00, small dot: 01, medium dot: 10, large dot: 11

01H:Run Length Encoding
bit length required for each pixel of image data
01H:1bit/pixel (for Micro, Normal x 1 x 2 dot
For every 1 bit of data:
0 no dot
1 a normal size dot for the current dpi
will be printed at the pixel location for that one bit.
02H:2bits per pixel (for dot sizes requiring 2 bits to designate the size)
For every 2 bits of data:
00 no dot
01 a small dot
10 a medium size dot
11 a large size dot
will be printed at the pixel location for those 2 bits.
Sample bits of data (for 4 pixels of an image), and the results of that data,
are displayed in the upcoming diagram.
nH = INT(horizontal byte count / 256)
= INT(((horizontal dot count) * (bit length of each pixel) + 7) / 8) /256
nL = MOD(horizontal byte count / 256)
= MOD(((horizontal dot count) * (bit length of each pixel) + 7) / 8) /256
mH = INT(vertical dot count / 256)
mL = MOD(vertical dot count / 256)
Total numbers of data bytes, according to the following formula:
k = (nH*256 + nL) * (mH*256 + mL)
