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