Lexmark Printer User Manual page 216

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:
AntiqueOlive
AntiqueOlive-Bold
AntiqueOlive-Italic
LetterGothic
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 4-5 to determine which Lexmark Optra S driver you should use.
Table 4-5: Lexmark Optra S Drivers

The PostScript commands to switch the compatibility modes are:
Forward compatibility:
Backward compatibility:
With the appropriate printer driver installed and selected, your software application
enumerates and selects the available PostScript fonts.
