I'm not a troff expert, but troff itself produces fairly "unprintable"
output, as opposed to nroff which creates pretty much ASCII output.
In other words, troff output doesn't usually resemble the text you desire.
My understanding is that troff output needs to be piped through a
translator which knows your printer's language.  I recently bought a
HP Laserjet IIp and plan to use Device-Independent Troff (ditroff)
piped through a package called Jetroff, which converts the troff
output to Laserjet language.  Jetroff comes with a set of downloadable
fonts and knows HP's proprietary printer language, so it can select
fonts, set line spacing, do bold/italics, etc.  I've also heard that
the new groff supports Laserjets as well.
