In addition to installed fonts, PostScript printers also accept downloadable outline fonts, which can be scaled to any size and printed in both portrait and landscape orientations. Downloadable PostScript fonts are available from several suppliers, including Adobe, Agfa, Bitstream, and Monotype.
Although PostScript downloadable outlines can be scaled to any size, Windows NT raster screen fonts cannot. If you specify a PostScript font size that does not have a corresponding screen font, Windows NT substitutes another screen font. This results in a little loss in display quality but no loss in print quality.
