Windows font types include: Type 1 fonts (or PostScript fonts), Type 3 fonts, Windows bitmap and vector fonts, TrueType fonts, and Open Type Fonts from Adobe (Windows 2000 and XP). Acrobat Distiller recognizes all Windows and Mac OS fonts however, the type of font that you use (for example, TrueType) determines how Acrobat Distiller handles the information for that font.
