[PrintService] Printer found but nothing is printed / Invalid Flavor

Question

Hi,
I'm trying to print a plain old UTF-8 String on a printer... Well this appears to me to be something simple, but i can't make it work.
The PrintJob is sent to the printer, i'm told that data transfer to the printer is done... But nothing is printed out from the printer!!
FYI, im working on a Mac... but with other software on my machine i manage to print anything with the printer found by my Java code.
Here is my code:
public void print() {
        LOG.info(incidentFormString.toString());
        DocFlavor docFlavor = DocFlavor.STRING.TEXT_PLAIN;
        PrintRequestAttributeSet printAttributes = new HashPrintRequestAttributeSet();
        printAttributes.add(MediaSizeName.ISO_A4);
        DocAttributeSet attributes = new HashDocAttributeSet();
        attributes.add(MediaSizeName.ISO_A4);
        // get the default printer
        PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
        LOG.info("Printer found: " + printService.getName());
        DocPrintJob job = printService.createPrintJob();
        Doc doc = new SimpleDoc(incidentFormString.toString(),
                docFlavor,
                attributes);
        job.addPrintJobListener(new PrintJobListener() {
            public void printDataTransferCompleted(PrintJobEvent printJobEvent) {
                LOG.info("printDataTransferCompleted");
            public void printJobCompleted(PrintJobEvent printJobEvent) {
                LOG.info("printJobCompleted");
            public void printJobFailed(PrintJobEvent printJobEvent) {
                LOG.info("printJobFailed");
            public void printJobCanceled(PrintJobEvent printJobEvent) {
                LOG.info("printJobCanceled");
            public void printJobNoMoreEvents(PrintJobEvent printJobEvent) {
                LOG.info("printJobNoMoreEvents");
            public void printJobRequiresAttention(PrintJobEvent printJobEvent) {
                LOG.info("printJobRequiresAttention");
        try {
            job.print(doc, printAttributes);
        } catch (PrintException e) {
            LOG.error(e.getMessage());
    }incidentFormString is the string i'm trying to print. I chechked its content, it is a proper String, so there re no problems regarding to this.
Here is what i get in my console on Mac
[AWT-EventQueue-0] INFO com.thalys.opalys.client.utils.IncidentFormPrinter - Printer found: 6-OPERA

Hey. Thanks for the quick answer
Sorry i forgot to mention those details.
My log were not verbose enough, but i simulated it on my Mac (i'm developing on my Mac and production is on a PC... the reason is that my company has not been able to give me a powerful enough PC to develop, so instead im using my Mac).
On my Mac it gives:
invalid flavor
at sun.print.Win32PrintJob.print(Win32PrintJob.java:290)
at Printing.main(Printing.java:40)
I also thought it was a problem of data that my printer can or cannot accept.
I used this code:
        DocFlavor docFlavor = DocFlavor.STRING.TEXT_PLAIN;
        LOG.info("DocFlavor Mime-Type: " + docFlavor.toString());
        PrintRequestAttributeSet printAttributes = new HashPrintRequestAttributeSet();
        printAttributes.add(MediaSizeName.ISO_A4);
        DocAttributeSet attributes = new HashDocAttributeSet();
        attributes.add(MediaSizeName.ISO_A4);
        // get the default printer
        PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
        LOG.info("Printer found: " + printService.getName());
        DocFlavor[] flavors = printService.getSupportedDocFlavors();
        for (DocFlavor flavor : flavors) {
            LOG.info(flavor.toString());
        }And got this log:
As you can see, the doc flavor i choosed is available on the printer (i just did the test on my Mac, but my PC locates the same default printer as you can see on the previous posts)
