  The old nroff/troff pair is obsolete. nroff didn't understand point
sizes or fonts. It was intended for a standard line printer with one
point size and one font. Troff knew about fonts and point sizes but it
was hard coded for a particular phototypesetter, the C/A/T.
  This old version of nroff/troff was replaced by ditroff (device
independent troff), which generates a device independent sequence of
instructions that have to be interpreted to be printed on a particular
printer. Thus, you can build device drivers for any printer by just
writing a version of this interpreter.
  We at UCLA have device drivers for our Imagen laser printer, our
line printer, our diablos, etc.
  To make the story short, you need ditroff to do what you want.
