POSTSCRIPTXEROX DOCUPRINT NPS GUIDE TO USING PAGE DESCRIPTION LANGUAGES 2-3see the Generic MICR Fundamentals Guide and the “MICR printing””chapter in the Guide to Configuring and Managing the System.DocuPrint NPS is capable of processing any legal Type 0, Type 1, orType 3 font. Fonts of any of these types may be included in adocument when it is sent to DocuPrint. Type 0, Type 1 and Type 3fonts may also be installed on the system using the font installationutility.Note: Only Type 0 OCF fonts are supported. Type 0 CID fonts arenot supported, even when downloaded.The DocuPrint PostScript interpreter does not use the “additionalmetrics” entry in a font dictionary.PostScript font substitution error messages appear on the “JOBMESSAGES AND ERRORS” page only when the requested font isnot present.DocuPrint NPS uses Courier when a requested font is not available.Loading fontsDocuPrint NPS accepts downloaded legal Type 0, 1 or 3 fontsthrough the standard means used on other PostScript devices fordownloading fonts. Type 0, Type 1, or Type 3 fonts may be loadedpermanently on the system by the system administrator using thefont installation utility. This method ensures that the desired fonts areavailable on the system and saves time later by avoiding therepeated transfer of fonts through the network.Note: Only Type 0 OCF fonts are supported. Type 0 CID fonts arenot supported.Caution: Downloading fonts with a PostScript file is discouragedbecause printer performance may be degraded significantly. Instead,install the desired fonts on the controller, then reference them fromwithin the PostScript file.User-defined fontsUser-defined fonts can contain bitmaps or define the shape ofcharacters through PostScript operators (lineto, curveto, fill). User-defined bitmap fonts are not portable across different output devices.You may notice a marked difference in the quality of rendering forbitmap fonts as printed on different laser printers. The differences areattributable to device-dependent features such as resolution, shapeof device pixels, and other characteristics. For further information onthese characteristics, see “Scan conversion details” in this chapter.
