//            printer.setOutputFormat(QPrinter::PdfFormat);
//            printer.setOutputFileName("writable.pdf");
          QPainter painter;
           if (! painter.begin(&printer)) { // failed to open file
               qWarning("failed to open file, is it writable?");
               return 0;
           }
          painter.drawText(00, 80, "Testing the automaization of this printer");
