7.3.  DINQUIRE Command 
The DINQUIRE command is used to get the information of the default value of a specific variable in the 
PJL Environment. (User Default Settings).   It is also possible to get the value for variables which PJL 
cannot change (Read-only).   
The returned value of User Default Settings is identical to the Control Panel Setting. 
This DINQUIRE command can request only one variable at a time.  If you would like to get information 
from more variables, send multiple DINQUIRE commands.    
Syntax: 
@PJL DINQUIRE [LPARM : personality] variable [<CR>]<LF> 
 
Response Syntax: 
@PJL DINQUIRE [LPARM : personality] variable <CR><LF> 
value <CR><LF> 
<FF> 
If the variable is not supported by the printer, it returns the response in the following syntax : 
@PJL DINQUIRE [LPARM : personality] variable <CR><LF> 
"?" <CR><LF> 
<FF> 
  LPARM : personality
