PostScript is a page-layout language used by many printers. The language contains the specifications of several different font formats. The main (FontForge) manual has a section describing how PostScript differs from TrueType. Type 1 -- This is the old standard for PostScript fonts. Such a font generally has the extension .pfb (or .pfa). A type 1 font is limited to a one byte encoding (ie. only 256 glyphs may be encoded). Type 2/CFF -- This is the format used within OpenType fonts. It is almost the same as Type 1, but has a few extensions and a more compact format. It is usually inside a CFF wrapper, which is usually inside an OpenType font. The CFF font format again only allows a 1 byte encoding, but the OpenType wrapper extends this to provide more complex encoding types. Type 3 -- This format allows full postscript within the font, but it means that no hints are allowed, so these fonts will not look as nice at small point-sizes. Also most (screen) rasterizers are incapable of dealing with them. A type 3 font is limited to a one byte encoding (ie. only 256 glyphs may be encoded). Type 0 -- This format is used for collecting many sub-fonts (of Type 1, 2 or 3) into one big font with a multi-byte encoding, and was used for CJK or Unicode fonts. Type 42 -- A TrueType font wrapped up in PostScript. Sort of the opposite from OpenType. CID -- This format is used for CJK fonts with large numbers of glyphs. The glyphs themselves are specified either as type1 or type2 glyph format. The CID font itself has no encoding, just a mapping from CID (a number) to glyph. An set of external CMAP files are used to provide appropriate encodings as needed.

Postscript

A technology developed and trade marked by Adobe Systems, Inc. On older systems, PostScript fonts require Adobe Type Manager. On the Mac, PostScript fonts consist of a printer font and a bitmap suitcase, which should always be kept together. PostScript fonts are generally more difficult to maintain, and PostScript fonts can have compatibility issues with some operating systems like Windows Vista. We highly recommend purchasing OpenType (or TrueType) fonts whenever possible.
