2-14 PCL Your Lexmark printer defaults to the forward compatibility mode to enable a HewlettPackard Company's driver to select the forward compatibility fonts. The Lexmark PCL emulation driver uses the backward compatibility mode and temporarily switches the printer to this mode. The PCL (PJL) emulation commands to switch the default compatibility modes are: Forward Backward ESC%-12345X@PJL DEFAULT LPARM:PCL LFONTCOMPATIBILITY=PCL6 @PJL RESET ESC%-12345X ESC%-12345X@PJL DEFAULT LPARM:PCL LFONTCOMPATIBILITY=PCL5 @PJL RESET ESC%-12345X Specialty PCL Fonts The following table lists the font selection commands for forward and backward compatibility mode for each of the five specialty PCL emulation fonts. Since the font selection commands for the forward and backward compatibility modes are identical, they are listed together in the table. These fonts are supported only in PCL 5 emulation, not in PCL XL.
