Font History and Font Formats
There are different font formats - which one should I choose?
OpenType fonts (.OTF) - OpenType is a scalable format for computer fonts that was initially developed by Microsoft™, then later joined by Adobe™ Systems. OpenType fonts were first announced in 1996 and Adobe™ completed conversion of its entire font library to OpenType around the end of 2002. In 2005, there were around 10,000 fonts available in OpenType font format, with Adobe's font library making up under a third of the total. As of 2006, every major font foundry and many minor ones were developing fonts in OpenType font format. TrueType fonts (TT or .TTF) - TrueType is a digital font technology that was designed by Apple™ Computer, and is now used by both Apple (Mac™) and Microsoft (PC) in their operating systems. Microsoft has distributed millions of quality TrueType fonts in thousands of different styles. TrueType fonts offer the highest possible quality on computer screens, printers, and include a wide range of features which make them very easy to use. PostScript Fonts (Type 1) - PostScript fonts predates TrueType by about six years.
First, there were many different font formats for digital fonts, none of which were standardized. Then Apple adopted Adobe's PostScript page description language (PDL) for its Apple LaserWriter printer in 1985. This, combined with the introduction of desktop publishing software, sparked a revolution in page layout technology.
