Question

I’m trying to print a HTML String under Ubuntu 10.10 using Java,
using this code:

public void printHTMLText(String text) throws Exception {
    if (printerName.equals(""))
        throw new Exception("no standart printer");
    PrintService printService = getCurrentPrinter();

    if (printService == null)
        helperFunctions
                .errorOut("Couldn't print HTML-Text: "
                        + text
                        + " because no current printer is given or current printer is not available");
    else {
        DocPrintJob printJob = printService.createPrintJob();
        DocFlavor[] avail = printService.getSupportedDocFlavors();
        DocFlavor htmlutf8 = null;
        for (int i = 0; i < avail.length; i++) {
            if (avail[i].toString().equals(
                    "text/html; charset=\"utf-8\"; class=\"[B\""))
                htmlutf8 = avail[i];
            helperFunctions.debugOut(avail[i].toString());
        }

        SimpleDoc doc;
        try {
            if (htmlutf8 == null)
                throw new PrintException(
                        "Sorry the chosen printer can't deliever text/html; charset=utf-8");
            // helperFunctions.debugOut(htmlutf8.getMimeType());

            doc = new SimpleDoc(text.getBytes("UTF-8"), new DocFlavor(
                    htmlutf8.getMimeType(),
                    htmlutf8.getRepresentationClassName()), null);

            printJob.print(doc, null);
            helperFunctions.infoOut("Printing HTML: " + text);

        } catch (PrintException ex) {
            helperFunctions.errorOut(ex.toString());
        }

    }
}

HTML Printing is, according to getSupportedDocFlavors(), supported.
I get no Java Errors and the printer responds. But all I get is an empty page.

What I’m doing wrong?
Did cost me quite some hours already and have no clue, since Java doesn’t report any error.

Thanks in advance

Try going with JTextComponent#print. Even if your program isn’t Swing related.
JEditorPane has HTML support and extends JTextComponent so it best fits the job.
