3-2 PJL Notes: • Parameters enclosed in square brackets ([ ]) are optional and not required for command execution. • The PJL interpreter requires uppercase for the @PJL prefix for all PJL commands except the Universal Exit Language (UEL) command. The rest of the PJL command is not case sensitive. The UEL command is case sensitive. • All PJL commands except UEL must be terminated with a line feed character (). Kernel Commands UNIVERSAL EXIT LANGUAGE Command The Universal Exit Language (UEL) command terminates the current printer language and allows dynamic switching into PJL. Syntax: %-12345X Notes: • If the printer receives this command while in PCL emulation, it performs a Printer Language Reset (ESCE) before exiting PCL emulation. • If the printer receives this command while in PostScript emulation, it performs an End-of-Job (EOJ) command before exiting PostScript emulation (Ctrl-D). The PJL commands must immediately follow the UEL command (that is, the X in the UEL syntax must be immediately followed by the @PJL of the next PJL command).
