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.
