6.1.4.

PJL environment variables 

This section lists the PJL environment variables. There are two kinds of PJL environment variables, General 
PJL environment variables and Printer language -specific variables. For all variables, except the read-only 
variables, value settings can be modified using 

@PJL SET

, 

@PJL RESET

, 

@PJL DEFAULT

, and 

@PJL 

INITIALIZE

. 

By using the 

@ PJL INQUIRE

 and 

@ PJL DINQUIRE

, you can request value settings for the printer 

features. For the details of these commands, see the next section. 

Note: 
1.   Use PJL commands only when no printer language commands are available for a desired feature. 

2.   When setting printer features with PJL, use the SET and RESET commands when you want to affect the 

current PJL  job only. 

If you want to affect more than the current job, use the DEFAULT and INITIALIZE commands. 

3.   Supported variables depend on your printer model.
