PlotManager, PlotConverter and PlotViewer in one program! The iNetBau PlotManager is a program for the output, conversion and viewing of plot files in the HP-GL, HP-GL/2 and HP-RTL formats. The output of plot files is possible even on plotters that don't support the HP-GL protocol! In addition, you can send plot files directly to a plotter with this program (regardless whether the plotter is connected by LPT, USB or ethernet). The files don't need to be interpreted and will thus be plotted genuine, looking the way they were produced by the user.
