    Description

      The printing seems to be totally broken on Mac OS X when printing to native printer. Here is a simple example:

      QTextDocument *d = new QTextDocument();
      QTextCursor cursor = QTextCursor(d);
      cursor.insertText("TEST");
      
      QPrinter *printer = new QPrinter(QPrinter::HighResolution);
      printer->setOutputFormat(QPrinter::NativeFormat);
      
      QPrintDialog printDialog(printer, this);
      printDialog.setOption(QAbstractPrintDialog::PrintShowPageSize,true);
      if (printDialog.exec() == QDialog::Accepted) {
         d->print(printer);
      }
      

      This shows print dialog, but nothing prints when dialog is accepted. Instead it gives the following message to application output dialog:

      QPainter::begin(): Returned false
      

      There is no problem when using Qt 4.8.4 on Mac.

      This works on Windows with Qt 5.1. It works also on Mac OS X with Qt 5.1 when printing to pdf file (setOutputFormat is PdfFormat).
