GL2PS:  http://www.geuz.org/gl2ps/

Its already integrated into VTK.  Grab VTK-4.4.  When building it,
turn on advanced options and turn on VTK_GL2PS.  Then use the
vtkGL2PSExporter class to generate PS/EPS/PDF output.  Certain things
like ImageActors don't work at all.  Otherwise basic primitives work
fine.  For volume rendering you can render the 3D actors as images and
embed the text into the PS output.
