Printing Arabic Using MIKE42 php Library

Does anyone manage to print Arabic using the mike42 library?

 	$connector = new NetworkPrintConnector($ip->printer_ip,9100);
 	$printer = new Printer($connector);
	$printer->setJustification(Printer::JUSTIFY_CENTER);	
	$printer->text("TAX INVOICE\n");
	$printer->text("TRN - {$shopdetails->vat_no}\n");
	$printer->bitImage($tux);
	$printer->feed(1);
	$printer->text('اثمخخخ');

I tried but nothing is printing at that place, it is just blank
