Hi tib
HP9872C should work using HPGL commands.
This is a link about HPGL: http://techref.massmind.org/techref/language/hpgl/commands.htm
This is a link about HPGL converter to Labview (example of commands) :http://hamiltondesign-consulting.com/labuseful.html#Drivers
Hope you can manage to control the plotter with this info.
Cheers
Alipio
