PostScript fonts are similar to TrueType fonts, but
they are supported by ATM (Adobe Type Manager). The advantage to using PostScript fonts is that there
are so many more of them than there are TrueType fonts. The one hitch to using PostScript fonts is
that ATM must be installed on whatever machine you use to create and deliver your presentation.
You should always use True Type or PostScript fonts
when creating presentations. These fonts remain the same, whatever the output device. You can create
a presentation on your laptop and project it from a different one at a hotel and be assured that the
image will appear the same in both locations.
PostScript fonts are designated by their .pfb extension.
Typically, they are located under drive/psfonts on Windows machines.
