At present, there are no utilities specifically for backing up fonts stored
on a LaserWriter hard disk.
Before installing the ROM upgrade, use the LaserWriter Font Utility (it
comes with the LaserWriter IINTX) to reformat the hard disk. After
installing the ROM upgrade and restarting the system, re-install fonts from
the original floppy disks. (If you purchased your fonts from Adobe, already
installed on a hard disk, contact Adobe for the procedure.)
Composite fonts are an exception: with the new version of the LaserWriter
Font Utility (version 2.0.1, shipping with upgraded printers), you can back
up composite fonts to floppy disks. (Composite fonts are small fonts hooked
together to support Kanji and Chinese characters, which require more than
the 256 characters supported in a single PostScript font.)
