There's a program called "gftodvi", which, as the name suggests, converts a
gf file (presumably a font full of character proofs) to a dvi file, which
you can print in the normal way. 

Well, almost; the dvi file calls on a special font called a "gray font" to
display the characters; each character in a gray font is a grey rectangle
of a certain size. So you need to have this gray font lying around, which
you may not already have, because if you (like me) were the first
metafonter at your site, no-one will have needed it before.

What complicates matters further is that the characters in a gray font
should be exactly a whole number of pixels wide and high, otherwise they
will leave ugly stripes on your printout (like in the Bell Centennial "R"
on p207 of the MFbook). Hence, the gray font isn't device independent; you
need different gray fonts, and hence different dvi files, for different
printers.

Appendix H (for "Hardcopy") of the MFbook tells how to create gray fonts
and how to use gftodvi. I'm not about to type the whole thing in, so you'll
have to find that BCoYours and read it.
