that you look up font sites in the internet, trying to find a free
font which looks similar to it.

Below you can find what the man page of grops (in the CVS of groff)
says about font installation. This topic comes up from time to time
on the list, so searching in the archive should give you further help.

======================================================================
FONT INSTALLATION
This section gives a summary of the above explanations; it can serve as
a step-by-step font installation guide for grops.
· Convert your font to something groff understands. This is either a
PostScript Type 1 font in PFA format or a PostScript Type 42 font,
together with an AFM file.
The very first characters in a PFA file look like this:
%!PS-AdobeFont-1.0:
A PFB file has this also in the first line, but the string is pre-
ceded with some binary bytes.
The very first characters in a Type 42 font file look like this:
%!PS-TrueTypeFont
This is a wrapper format for TrueType fonts. Old PS printers might
not support it (this is, they don't have a built-in TrueType font
interpreter).
If your font is in PFB format (such fonts normally have `.pfb' as
the file extension), you might use groff's pfbtops(1) program to
convert it to PFA. For TrueType fonts, try ttftot42 or fontforge.
For all other font formats use fontforge which can convert most
outline font formats.
· Convert the AFM file to a groff font description file with the
afmtodit(1) program. An example call is
afmtodit Foo-Bar-Bold.afm textmap FBB
which converts the metric file `Foo-Bar-Bold.afm' to the groff font
`FBB'. If you have a font family which comes with normal, bold,
italic, and bold italic faces, it is recommended to use the letters
R, B, I, and BI, respectively, as postfixes in the groff font names
to make groff's `.fam' request work. An example is groff's built-
in Times-Roman font: The font family name is T, and the groff font
names are TR, TB, TI, and TBI.
· Install both the groff font description files and the fonts in a
`devps' subdirectory of the font path which groff finds. See the
ENVIRONMENT section in the troff(1) man page which lists the actual
value of the font path. Note that groff doesn't use the AFM files
(but it is a good idea to store them anyway).
· Register all fonts which must be downloaded to the printer in the
`devps/download' file. Only the first occurrence of this file in
the font path is read. This means that you should copy the default
`download' file to the first directory in your font path and add
your fonts there. To continue the above example we assume that the
PS font name for Foo-Bar-Bold.pfa is `XY-Foo-Bar-Bold' (the PS font
name is stored in the internalname field in the `FBB' file), thus
the following line should be added to `download'.
XY-Foo-Bar-Bold Foo-Bar-Bold.pfa
