Printers use "postscriptname" defined in a font file while searching for
fonts. psname.txt provides a sample of how to read that information from a
font backend. It is not mandatory - but its presence will prevent nasty
surprises. In its absence, Lisp code uses font file base name. If the file
name doesn't match postscriptname, printing might fail - "might" because
printer will try its best to substitute a suitable font.
Theoretically, there's no dependency except Ghostscript which does most of
the heavy lifting for printing in Emacs. Fonts other than Truetype might
require additional configuration as defined in Ghostscript manual.
