************************************************************************
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.
