+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.
