Purpose Prints
mSpecifies the dot density
nL, nH | Specifies the total number of columns of graphics |
| data that follows (number of dot columns) = ((nHx |
| 256) + nL) |
d1 … dk | Bytes of graphics data; k is determined by multiplying |
| the total number of columns times the number of |
| bytes required for each column |
Dot density is described in the table below:
