************************************************************************
The OKIDATA Pacemark 2410 has a serious  design flaw in that it lacks  a
command to reset to  power-on state.  This is  serious, because it  uses
ETX to enter graphics mode, ETX STX  to exit graphics mode, and ETX  ETX
to mean ETX as graphics  data.  This means that  a single ETX sent  from
the host may cause it to enter graphics mode, or generate an error if it
is already in graphics mode.  Similarly, an ETX STX will enter  graphics
mode if it is not already in  it, instead of exiting graphics mode.   We
therefore turn on graphics mode for  each line, then turn it off  again.
That way, there may be some remote hope of resynchronizing if we lose an
ETX due to line errors along the way.

From an efficiency standout, it is regrettable that it has no run-length
encoding of graphics data.  The  output quality and speed are  otherwise
quite reasonable as low-cost dot matrix printers go.
