How to send raw data to a printer using Java

I am trying to create a simple program that sends a string to a printer for printing. This is my program as follows:

import javax.print.Doc;
import javax.print.DocFlavor;
import javax.print.DocPrintJob;
import javax.print.PrintException;
import javax.print.PrintService;
import javax.print.PrintServiceLookup;
import javax.print.SimpleDoc;

public class PrinterTest {
  public static void main (String [] args) throws PrintException {
    DocPrintJob job = null;
    PrintService[] printServices = 
    PrintServiceLookup.lookupPrintServices(null, null);
    System.out.println("Number of print services: " + printServices.length);
    for (PrintService printer : printServices) {
        System.out.println("Printer: " + printer.getName());
        if (printer.getName().contains("ZM400")) {
            String hello = "Hello";
            DocFlavor flavor = DocFlavor.STRING.TEXT_PLAIN;
            Doc doc = new SimpleDoc(hello, flavor, null);
            job = printer.createPrintJob();
            job.print(doc, null);
        }
    }
  }
}

I export this as a jar file and run it on the command line (Windows) using:

java -jar PrinterTest.jar

The program starts and runs through all installed printers on the computer. But when it hits the printer I'm looking for, I get the following error:

Exception in thread "main" sun.print.PrintJobFlavorException: invalid flavor
  at sun.print.Win32PrintJob.print(Unknown Source)
  at PrinterTest.main(PrinterTest.java:21)

Not quite sure what I'm doing wrong here, as the printer I'm looking for does appear.

-The following link is used for the link: http://docs.oracle.com/javase/7/docs/technotes/guides/jps/spec/jpsOverview.fm4.html

-Changing the change DocFlavor flavor = DocFlavor.STRING.TEXT_PLAINto DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE, but we get an error IllegalArgumentException: data is not of declared type.

- Doc doc = new SimpleDoc(hello, flavor, null) Doc doc = new SimpleDoc(hello, null, null), , .
