troff question

[Mr. Video]

I have prepared a program guide for the new Star Trek: The Next Generation
series.  I use the NewCenturySchlbk font that is available on the Apple
LaserWriter Plus printer.  As a result, the .fp macro is called by the
preprocessor.  Unfortunately, some users of the guide cannot print using
that font.  I have created a STAR TREK like logo that is positioned
absolutely on the paper.  Users of the default Times-Roman font do not
get a lined up character set.

I would like to know if troff can be asked what the current fonts are
loaded.  I don't care what they are, except that I will use different
positioning for Times-Roman (default, or other than what I used) and for
the font that I use (called N, NI, NB).

If someone knows a trick for finding this out, I would appreciate a piece
of e-mail from comp.unix.questions readers, as I don't normally read that
group.

Your help will make quite a few rec.arts.startrek guide printing people
happy.
