Print Service problem

Question

I'm trying to print using print service. I do the following:
Doc getPrintDoc()
Doc doc = null;
DocFlavor flavor = DocFlavor.INPUT_STREAM.TEXT_HTML_UTF_8;
StreamPrintServiceFactory[] psFactories = StreamPrintServiceFactory.lookupStreamPrintServiceFactories(flavor,flavor.BYTE_ARRAY.PCL.getMimeType());
try
File f=new File(GlobalVariables.REPORT_TMP_DIR+"\\"+GlobalVariables.REPORT_FILE_NAME);
System.out.println("path: "+f.getPath());
FileOutputStream fos = new FileOutputStream(f);
// ByteArrayInputStream bis = new ByteArrayInputStream(pane.getText().getBytes());
// StreamPrintService psService = psFactories[0].getPrintService(fos);
doc = new SimpleDoc(fos, flavor, null);
catch (FileNotFoundException fnfe) {fnfe.printStackTrace();}
return doc;
void printUsingPrintServices()
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printJob = service.createPrintJob();
try {printJob.print(getPrintDoc(), aset);}
catch (PrintException pe) {pe.printStackTrace();}
All the time i get the same excaption:
java.lang.IllegalArgumentException: data is not of declared type
     at javax.print.SimpleDoc.<init>(SimpleDoc.java:82)

At a guess, your fos doesn't match your flavor (see the API for SimpleDoc). FileOutputStreams are used for writing data to a file. You want to read data from a file into the print service, so use a FileInputStream instead.
