TrueType fonts are digitized fonts originally developed by Apple Computer to avoid paying royalty fees to Adobe, owner of the Type 1 font format. The TrueType technology provides the highest quality of fonts on displays and printers. The format allows for precise control of each character's appearance at many sizes.
The Type 1 font format was originally used on Apple brand computers, but the licensing was expensive and Adobe demanded that the format stay closed with no one else allowed to work on developing the format. Apple's TrueType was less expensive and was opened up to Microsoft for use in its personal computers as well. TrueType for Apple products was first released in 1991 and for personal computers in 1992.
