Printing tables takes a long time

Question

Hi,
I am using the printerJob.printDialog() to print tables (I implemented a print method).
The problem is that when the table has many entries printing takes very long time (printing table of 100 entries might take a couple of minutes).
I am using the SwingWorker when printing in the following way:
final SwingWorker worker = new SwingWorker() {
    public Object construct() {
        try
            PrinterJob printerJob = PrinterJob.getPrinterJob();
            printerJob.setPrintable(printable);
            if (!printerJob.printDialog())
                return 0;
            NMSMainWindow.getInstance().setCursor(new Cursor(Cursor.WAIT_CURSOR));
            printerJob.print();
            NMSMainWindow.getInstance().setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
            JOptionPane.showMessageDialog(NMSMainWindow.getInstance(),  "Printing completed successfully", "Print", JOptionPane.INFORMATION_MESSAGE);     
        catch (PrinterException pe)
            pe.printStackTrace();     
            NMSMainWindow.getInstance().setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
    return 0;
worker.start();My question is: Is there a way to send a print job in the background, but in the meanwhile, while it is being processed, keep on working?
Thanks,
Efrat

Edit init<sid>.ora
and add the following line
_fast=true
Seriously, you need to run the normal selects to find out 'what it is waiting for' and/or run statspack.
Information about this can be found on the websites you so far avoided to use.
