In an innovative marketing approach, Adobe recently put their entire font collection on a CD-ROM in a "locked" format. When you buy the disk, the company gives you the passwords to unlock the font combinations you select. Later, if you want additional fonts, you simply pay a fee for the necessary passwords.
Developers also produce outline fonts that they put in the public domain or distribute as shareware. In the case of shareware fonts, the font you initially receive may not include all the characters, but the shareware designer will send a disk with the full version when you remit the shareware fee.
Commercial fonts are usually well-designed throughout, but the visual quality of shareware and public domain designs varies, so test these fonts thoroughly before including them in your collection.
A Legal Note
Several shareware and public domain fonts produce documents that look identical to those printed with available commercial fonts. This might seem like an infringement of copyright, but it can be legal.
Under U.S. copyright law, any shape that can be read by a human as part of a character set cannot be copyrighted. So, it is possible to legally duplicate a commercial outline font, as long as you meet two conditions:
1. The code sent to the printer to reproduce the characters cannot be the same as the code sent by the original font.
2. You cannot use the original font name.
Note that it is a violation to copy outlines of symbols such as the character included in all Adobe fonts for the Macintosh and other special characters, such as "dingbats".
