TrueType is compatible with any output device as it is a self-contained driver
and font set. Since you are running System 6.0.7, you have to install the
TrueType INIT, and the specific TrueType fonts you wish to use. System 7
has the functionality of TrueType built in, so those running System 7 do not
have to install the INIT, just the specific fonts they wish to use.
The INIT is available on the StyleWriter and Personal LaserWriter LS
diskettes, or through authorized Apple resellers.
