Printing problem in windows

[joseph]

Ok, I got know there is a problem
in this code

printer.setOutputToFile ( FALSE );

printer.setOutputToFile ( FALSE );

To copy to clipboard, switch view to plain text mode 

Once commented, the control goes to this

if ( printer.setup( this ) )

if ( printer.setup( this ) )

To copy to clipboard, switch view to plain text mode 

Finally to this function..

bool QPrinter::setup(QWidget *parent)
{
    Q_D(QPrinter);
    return qt_compat_QPrinter_printSetup(this, d, parent)
#ifdef Q_WS_MAC
        && qt_compat_QPrinter_pageSetup(this, parent);
#endif
        ;
}

bool QPrinter::setup(QWidget *parent)
{
    Q_D(QPrinter);
    return qt_compat_QPrinter_printSetup(this, d, parent)
#ifdef Q_WS_MAC
        && qt_compat_QPrinter_pageSetup(this, parent);
#endif
        ;
}

To copy to clipboard, switch view to plain text mode 

The application crashes. Any idea

Ok one more thing, I get this warning QPrintDialog, Only native format supported. What to do???

-->Edit-->
Ok I have changed the code from

if (printer->setup(parent))
     ...
you can rewrite it as
 QPrintDialog dialog(printer, parent);
 if (dialog.exec())

if (printer->setup(parent))
     ...
you can rewrite it as
 QPrintDialog dialog(printer, parent);
 if (dialog.exec())

To copy to clipboard, switch view to plain text mode 

Still there is crashing, I still get QPrintDialog, Only native format supported,
In int QPrintDialog::exec() function "ep" which is "QWin32PrintEnginePrivate *ep;" is 0. Any idea???

Ok, got it... I need to do this
printer.setOutputFormat ( QPrinter::NativeFormat );
and works fine.
Is it correct????
