4-14 PostScript Your printer defaults to the forward compatibility mode and the Lexmark PostScript driver uses this mode. For backward compatibility with the Lexmark Optra S family of printers, use the latest version of the Lexmark Optra S driver which sends the PostScript command to switch to backward compatibility mode. (The original Lexmark Optra S driver does not send this command.) See Table 4-6 to determine which Lexmark Optra S driver you should use. Table 4-6: Lexmark Optra S Drivers If you need the Lexmark Optra S driver for ... Windows 2000, Windows XP Windows NT 4.0 Windows 9x, Windows Millennium Edition (Me) Windows 3.x Use ... Version 7.2 or later of LEXPSNT Version 1.8 or later of LEXPSNT Version 4.32 or later of LEXPS Version 4.02 or later of LEXPS The PostScript commands to switch the compatibility modes are: Forward compatibility: statusdict begin PS3fonts end (temporary, changes the PostScript job only) setsystemparams (permanent, changes the default in NVRAM) Backward compatibility: statusdict begin PS2fonts end (temporary, changes the PostScript job only) setsystemparams (permanent, changes the default in NVRAM) With the appropriate printer driver installed and selected, your software program enumerates and selects the available PostScript fonts.
