Select Graphics Mode: Selects graphics mode m (see table below) for
n1 + (n2 x 256) columns. The variables n1 and n2 represent the
number of data bytes to be sent that will be interpreted as graphics.
If the number of graphics columns to be printed causes printing to
exceed the right margin, all data beyond that margin will be ignored.

Example:
Normally, when the printer receives the ESC L command, the dot
density is 120 dpi x 72 dpi vertical. By using this command, you can
reassign that density to 60 dpi horizontal x 72 dpi vertical by sending
the following:
CHR$(27);"?";"I";CHR$(0);
