Example 

The application sends the following command to the printer : 

<ESC>%-12345X@PJL<CR><LF> 
@PJL INFO CONFIG<CR><LF> 
<ESC>%-12345X 

The printer may send back the answer for the above INFO command : 

@PJL INFO CONFIG<CR><LF> 
IN TRAYS [1 ENUMERATED]<CR><LF>

MEMORY category 

The application can use the 

@PJL INFO MEMORY

 command to check the size of total free memory and 

the largest free memory block in the printer. 

The free memory size may vary according to the personality (printer language).  In order to know the free 
memory size in PCL, use the

 <ESC>*s1M

 (Free Space command) in the PCL status readback commands.  

Example  

The application sends the following command to the printer : 

<ESC>%-12345X@PJL<CR><LF> 
@PJL COMMENT the INFO MEMORY command follows<CR><LF> 
@PJL ECHO This is a sample 2-28-1993 19:03:00<CR><LF> 
@PJL INFO MEMORY<CR><LF> 
<ESC>%-12345X 

The printer sends back the answer for the above command :
