Hello you can use something like this.

QPrinter printer(QPrinter::HighResolution);
printer.setOrientation(QPrinter::Portrait);
QPrintDialog dlg(&printer, this);
dlg.setWindowTitle("Print");

if (dlg.exec() == QDialog::Accepted)
{
    QWidget* widget = new QWidget(his); // this widget is your pdf widget
    QPixmap printPixmap(widget->width(),widget->height());
    widget->render(&printPixmap,QPoint(),QRegion(0,0,widget->width(),widget->height()));
    QPainter painterPixmap(&printer);
    painterPixmap.scale(4,4);
    painterPixmap.drawPixmap(printer.pageRect().topLeft(), printPixmap, printPixmap.rect());
}
