Description With this Escape sequence, graphics printing with 9 print dots per dot row is selected. For
each row of dots two graphics bytes are required. The first byte controls the upper eight
print dots and the second controls only the lowest print dot.
m = 0 selects normal graphics resolution (60 dpi).
m = 1 selects double graphics resolution (120 dpi).
The data following the graphics ESC sequence are printed as a dot pattern. The parame-
ters n1 and n2 define the number of graphics bytes.
