4.6. Printer Language Switching
There are three methods of switching printer languages.
4.6.1. Explicit switching
Explicit switching means the method which uses the PJL ENTER LANGUAGE command to switch to the
desired emulation. As the desired emulation is explicitly specified, this method is the most reliable.
4.6.2. Implicit switching
If a default printer language is configured, and the PJL ENTER command is not described on a PJL line, the
printer uses the default printer emulation. This may not always select your desired emulation.
4.6.3. Context switching
If the printer is set to 'automatic emulation selection' and the PJL ENTER command is not described in the PJL
command, the printer investigates the incoming data and decides the required printer emulation. The printer
can select the printer language by this switching, however, the PJL ENTER command is recommended to
select the printer language accurately.
