try {
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
pras.add(new Copies(1));

PrintService pss[] = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.GIF, pras);

if (pss.length == 0)
throw new RuntimeException("No printer services available.");

PrintService ps = pss[0];
System.out.println("Printing to " + ps);

DocPrintJob job = ps.createPrintJob();

FileInputStream fin = new FileInputStream("YOurImageFileName.PNG");
Doc doc = new SimpleDoc(fin, DocFlavor.INPUT_STREAM.GIF, null);

job.print(doc, pras);

fin.close();
} catch (IOException ie) {
ie.printStackTrace();
