Common questions about fonts
Here are some questions that often come up about fonts.
What kind of fonts should I buy?
Bitmapped fonts are best for screen display but don’t look as good when you
print them. PostScript fonts look great on paper if you have a PostScript
printer or Adobe Type Manager.
TrueType fonts are the best all-purpose fonts to use for your Macintosh
monitor and non-PostScript printers. If you need to display fonts with
extremely accurate typographic features such as ligatures and kerning, install
QuickDraw GX on your system and buy QuickDraw GX TrueType fonts.
Why don’t all of my fonts appear in the Fonts menu?
You may not have all of your fonts placed correctly. In system software
versions 7.1 and 7.5, all the fonts should be installed in the Fonts folder in the
System Folder.
Additionally, some application programs let the user decide which fonts
should appear in the Fonts menu. Check the manuals that came with your
programs.
Why can’t I see my Monaco 9, Geneva 9 and 12, and Chicago 12 bitmapped fonts?
These fonts are used by your Macintosh to display information correctly.
Because the Macintosh needs these fonts, the Finder makes them invisible to
prevent users from removing them.
