A type of font designed by Adobe. These fonts are well supported by almost all linux applications, because they have been supported by the X server architecture and the PostScript standard for a long time. Postscript fonts are distributed in many different formats. Typically, a UNIX PostScript font is distributed as an afm (adobe font metric) file, and an outline file, which is usually a .pfb (printer font binary) or .pfa (printer font ascii) file. The outline file contains all the glyphs, while the metric file contains the metrics.
