hi.
why the printer in this function:

void dlg_account::on_btn_print_clicked()
{    
      QPrinter printer(QPrinter::HighResolution);
      printer.setFullPage( true );
           QPrintPreviewDialog preview(&printer, this);
           preview.setWindowFlags ( Qt::Window );
           connect(&preview, SIGNAL(paintRequested(QPrinter* )), SLOT(print(QPrinter* )));
           preview.exec();
}

void dlg_account::on_btn_print_clicked()
{    
      QPrinter printer(QPrinter::HighResolution);
      printer.setFullPage( true );
           QPrintPreviewDialog preview(&printer, this);
           preview.setWindowFlags ( Qt::Window );
           connect(&preview, SIGNAL(paintRequested(QPrinter* )), SLOT(print(QPrinter* )));
           preview.exec();
}
