try{
System.out.println(" Zebra Print testing!");
// Prepare date to print in dd/mm/yyyy format
Date now = new Date();
SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");
String dateString = format.format(now);
// Search for an installed zebra printer...
// is a printer with "zebra" in its name
PrintService psZebra = null;
String sPrinterName = null;
PrintService[] services = PrintServiceLookup.lookupPrintServices(null,
null);
for (int i = 0; i < services.length; i++) {
PrintServiceAttribute attr =
services[i].getAttribute(PrinterName.class);
sPrinterName = ((PrinterName) attr).getValue();
if (sPrinterName.toLowerCase().indexOf("zebra") >= 0) {
psZebra = services[i];
break;
}
}

if (psZebra == null) {
System.out.println("Zebra printer is not found.");
return;
}
