[comp.text] troff font expansion

ping@cubmol.bio.columbia.edu (Shiping Zhang) (12/21/90)

We use standard troff and its output is piped to lpr (on Sun os4.0.1).
The default mounted fonts are R, I, B and S on positions 1, 2, 3, and 4
respectively.  Now I need another font, e.g. Courier. How I can expand
the list of fonts to troff?  The document says fonts can be mounted or
replaced on positions 1, 2, and 3 by using the .fp command.  But I tried
and the results are not expected. For example, I tried to switch the
default fonts R, B, I to, say, positions 3, 1, 2, respectively, but the
output still followed the default setting. Thanks for any information.
