Define ZPL as a pre-specified language with Link-OS-Android?

Define ZPL as a pre-specified language with Link-OS-Android?

 

I using this :

PrinterLanguage pl = printer.getPrinterControlLanguage();

 

But I get this as a result:

  LINE_PRINT

 

I need from Link-OS-Android since I use many IMZ320 printers and I can not configure one by one and it is not correct to use Zebra Setup Utilities.

Thank you very much!
