The bottom line is that the TrueType rasterizer CANNOT be downloaded to
the original LaserWriter which has ROM version 1.0 (PostScript version
23.0). Thus, it CANNOT print TrueType fonts. The TrueType rasterizer can
only be downloaded to LaserWriters with PostScript version 38.0 or ABOVE.
PostScript version 38.0 or 47.0 ROMs are LaserWriter Plus ROMs which can
be installed on an original LaserWriter, making it a LaserWriter Plus.
In terms of which LaserWriter driver to use, version 6.1 or greater is
required to print TrueType.
