The facts as I understand them:

1)  Pic generates input to troff, according to troff's input language.

2)  Troff generates a device-independent output.

3)  Various filters take the troff output and generate device-specific codes.
    (I have Eroff, and it has filters to convert troff output to
     HP LaserJet, Imagen Impress, and PostScript).

Therefore,

    It is possible for pic drawings to appear on a PostScript printer.

However,

    Features of PostScript, such as shading are not in the repertoire
    of what troff handles, and thus, no output of pic can instruct
    troff to generate the appropriate output.

Oh, well.

John
