EXPLANATIONThis instruction is ignored when the rear-panel switch
labeled Y/Dis set to D.When that switch is set to D,it is not possible to
turn the plotter off programmatically.
Beginning with the next character, the plotter will assume a passive
state and remain in that state until a plotter on instruction is received.
Any HP-GL instructions remaining in the buffer at the time that a i
plotter off instruction is received are executed. However, no additional
HP-GL instructions will be accepted by the plotter.
NOTE: A Break signal from the terminal will have the same effect as a
plotter off instruction. I
