This is a specialised case of installing a font,
but it is almost never necessary — it’s inconceivable that any (even
remotely) recent system will not have the fonts already
installed. You can confirm this (near-inevitable) fact by trying the
fonts. On a system that uses
dvips (almost all do), try
latex sample2e dvips -o sample2e.ps sample2e
at a “command prompt” (
shell, in a Unix-style system,
“DOS box” in a Windows system).
If the command works at all, the console output of the command will
include a sequence of Type 1 font file names, listed as
<_path_/cmr10.pfb> and so on; this is
telling you it’s copying information from the Type 1 font, and you
need do no more.
If the test has failed, you need to install your own set of the fonts;
the distribution (including all the fonts the AMS designed and
produced themselves) is now described as
bundle contains metric and map files — all you need to
install the fonts.
