Other commands that can be sent to the V8.5E Centronics

NOTE: These commands must be sent when the plotter is
in print mode. The commands will be ignored and inter-
preted as raster data if they are sent at any other time.
The V8.5E plotter also obeys standard control characters
which must be sent when the plotter is in print mode:
04 end of transmission
0A line feed
0C form feed
NOTE: print mode on the V8.5E means that all bytes that are
received by the plotter are interpreted as ASCII characters and
printed at 108 characters/line.
