Also keep in mind that HP-GL is a vector-oriented language with text and polygon capability, but no raster. (HP-GL/2 adds some raster capability.) SOME PostScript files can be converted to HP-GL, and some cannot. If you are looking at a picture that looks like it could be done on a plotter (i.e., no bitmaps, no grey scales, simple fonts), a conversion is feasible. You'd be much better off trying to convert PostScript to PCL5 (which includes HP-GL/2) for a LaserJet III. There's a much better match of capabilities there.
