Exiting from Raster Plot
To exit from raster plot, you must set Configuration Option 43.0, and send
one additional line terminator character after the last dot row is printed. An
additional line terminator will cause the paper to advance vertically to the
start of the next character line, even if the last printed dot row was between
character line boundaries.
