You cannot reduce or remove the embedding restrictions that were set in
the source font by the original creator of the font. You can either leave the
embedding restrictions unchanged or set the restrictions higher. For
example, if the original font has the embedding level Editing of the
document is allowed and you change the level to Everything is
allowed in the Preferences dialog, then in the output font the original
embedding level will be retained rather than the one you set. But if you
change the embedding level to Not allowed, then the embedding in the
output font will be changed.
Additionally you can use the Allow subsetting and the Bitmap
embedding only options for more control of the embedding fonts into
documents.
The Default font's vendor pop-up allows you to set the special up-to-
four letter length code that is assigned to most TrueType producers to
identify their fonts. An uppercase vendor code must be registered with
Microsoft or Apple. All registered Vendor codes known at the time of
TransType’s release are placed in the pop-up menu. You don't need to
change the default 'PYRS' vendor code if you do not have your own.
