Lexmark Printer manual Lexmark Optra S Drivers

PostScript

PostScript emulation also has a backward compatibility mode that changes the metrics of eight of the resident fonts to match the fonts in the Lexmark Optra S family of printers. The eight fonts are:

AntiqueOliveLetterGothic-Bold

AntiqueOlive-BoldLetterGothic-Italic

AntiqueOlive-ItalicMarigold

LetterGothicUnivers-Bold

Note: In backward compatibility mode, the LetterGothic-BoldSlanted font is unavailable.

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 4-5to determine which Lexmark Optra S driver you should use.

Table 4-5: Lexmark Optra S Drivers

Windows 2000, WindowsXP	Version 7.2 or later of LEXPSNT

The PostScript commands to switch the compatibility modes are:

Forward compatibility:

statusdict begin PS3fonts end	(temporary, changes the PostScript job only)
<</UseOldfonts false>> setsystemparams	(permanent, changes the default in NVRAM)
Backward compatibility:
statusdict begin PS2fonts end	(temporary, changes the PostScript job only)

With the appropriate printer driver installed and selected, your software application enumerates and selects the available PostScript fonts.
