How to Send Print to Epson EM T82 POS Printer from Xamarin Forms App?

Here I am starting a new activity for print data to my Epson TM T82 POS Thermal printer.And my Printer is connected through USB OTG Cable

public void printData()
        {
            String dataToPrint = "$big$This is a printer test$intro$posprinterdriver.com$intro$$intro$$cut$$intro$";

            Intent intentPrint = new Intent();

            intentPrint.SetAction(Intent.ActionSend);
            intentPrint.PutExtra(Intent.ExtraText, dataToPrint);
            intentPrint.SetType("text/plain");

            this.StartActivity(intentPrint);
        }

but this code is not working as expected.

so how to send few lines of text for print to Epson POS Thermal from Xamarin Forms App?.
