This command group is partly supported. With these commands it is possible to enter/leave the PJL interpreter.
Universal Exit Language
This command is supported; control is passed to the PJL interpreter. It parses the data until it is no longer PJL. Supported commands are executed/handled.
@PJL COMMENT
This command is supported. Information following COMMENT is flushed (it is, after all, just comments...).
@PJL ENTER LANGUAGE
This command is supported. The PJL ENTER LANGUAGE command is used to select either the PCL5e interpreter or the PCL-XL interpreter.
NOTE
The HP-GL/2 interpreter is incorporated within the PCL5e interpreter. As a consequence, it is not possible to switch to PostScript or other PDLs. This is the same behaviour as other Canon products.
