There are three types of fonts, True Type is an outline font standard developed by Apple Computer in the late 1980s as a competitor to Adobe’s Type 1 fonts used in PostScript. It has become the most common format for fonts on both the Mac OS and Microsoft Windows operating systems.
OpenType fonts are related to TrueType fonts, but have a greater basic character set, including small capitalization, an old-style numerals system, and more capable of detailing shapes, such as glyphs and ligatures. OpenType fonts easier to read and readable in all sizes and can be sent to any printer or other output device that is supported by Windows.
PostScript fonts (like Adobe type 1 & type 2 fonts are smooth, detailed, and of high quality and are good for printing, especially professional printing, for example books or magazines.
