Function:
1)If c has any value other than the above, this command terminates at the instant that c is processed.
If v has any value other than the above, or if h has any value other than the above, this command is ignored.
2)The actual image pattern is generated according to a raster method determined by the following parameters:
c: printing mode
00H: full graphics mode
01H:
v:printing density in the vertical direction v/3600 (dpi)
h:printing density in the horizontal direction h/3600 (dpi)
m:number of dots in the vertical direction
nL, nH: number of dots in the horizontal direction 256 x nH + nL (dots)
k:number of items of data = m x int((nH x 256 + nL + 7)/8)
d:data
Full graphics mode
In full graphics mode, all of the data is transferred in raster format. At this time, for the last data byte on the right, the portion up until the number of dots in the horizontal direction is valid.
The total amount of data sent is k = int((256 x nH + nL + 7)/8) x m bytes.
