Javax.print problem: data not of declared type

Question

Hi all,
I'm trying to print a simple text-only document with the below code but it keeps giving me an illegal argument exception. By the way, I've tried all the combinations of DocFlavor.*.* and SERVICE_FORMATTED.PRINTABLE and SERVICE_FORMATTED.PAGEABLE are the only ones working for me. Is this normal?
Thanks!

          PrintService ps[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
          PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
          PrintService service = ServiceUI.printDialog(null, 200, 200, ps, defaultService, flavor, pras);
          if (service != null) {
               try {
                    DocPrintJob job = service.createPrintJob();
                    DocAttributeSet das = new HashDocAttributeSet();
                    FileInputStream fis = new FileInputStream("report.txt");
                    Doc doc = new SimpleDoc(fis, flavor, das);
                    try {
                         job.print(doc, pras);
                         System.err.println("Job sent to printer.");
                    } catch (PrintException e) {
                         System.err.println("Print error!\n\n" + e.getMessage());
               } catch (FileNotFoundException e) {
                    System.err.println("File not found!\n\n" + e.getMessage());
}

Hi duffymo,
I've tried all the available DocFlavors and even wrote a little program to list all my supported DocFlavors. And, I've only got 2 available for each of my printers, one being a Canon i320 and the other is a Adobe PDF printer.
import javax.print.*;
import javax.print.attribute.*;
class listDocFlavor
  public static void main(String args[])
    PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
    DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PRINTABLE;
    PrintService ps[] = PrintServiceLookup.lookupPrintServices(flavor, pras);
    for (int j = 0; j < ps.length; j++) {
      DocFlavor df[] = ps[j].getSupportedDocFlavors();
      for (int i = 0; i < df.length; i++)
        System.err.println(j + ": " + df);
