Designers can limit the frequency that embedded fonts must be transferred to the users' computers if they anticipate fonts that might already be installed. The following example uses an embedded font as a secondary font face, if by chance the preferred font is not already installed on the client computer. For information about the current implementation of embedded fonts in Internet Explorer 4.0, see Limitations in Internet Explorer 4.0 . Different Levels of Font Embedding TrueType fonts have embedding permissions encoded within them that determine how they can be used by tools that convert them into the embedded font format. The creators of these fonts have decided not to allow embedding.

If you come across a no-embedding font that you would really like to use, contact the supplier and ask about a possible upgrade. Print and preview fonts can be embedded, but only within pages that remain static on the client side. Installable fonts are treated as editable fonts by Internet Explorer 4.0. Installable fonts will not be installed in your visitors fonts folder. The main reason for this is that during the course of users' Web travels, they could easily find their fonts folder stuffed with hundreds of full and subsetted fonts that they do not want or need.
