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 :

In this example, IN TRAYS [2 ENUMERATED] indicates that there are two options in IN TRAYS (paper
sources) and MEMORY=2097152 indicates the RAM size in the printer is 2097152 bytes.
7.5.3. 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>
