Apple Color StyleWriter 4500 - Manual (Page 101)

Where fonts are stored
All fonts for your Color StyleWriter 4500 printer reside in special places
within the System Folder. To install fonts, you drag them to the System
Folder. Your Macintosh will automatically put them where they belong—in
the Fonts folder within the System Folder.
The Fonts folder can contain a total of 128 font suitcases (described in the
next section), plus any number of PostScript fonts, up to the available storage
capacity of your hard disk.
IMPORTANT Fonts installed in other folders or in the top level of the System
Folder may not work correctly. Additionally, bitmapped and TrueType fonts
stored outside of suitcases may not work correctly.
