In printPreview there is a call to a method in a class:
...
m_document->setPageSize(printer->pageRect().size());
...
QString site =" <table bgcolor=\"lightGray\" border=\"0\"><tbody><tr ><td width=\"800\">" + QObject::tr("Sito") +"</td></tr></tbody> </table>";
m_cursor.insertHtml(site);
m_cursor.insertText(QObject::tr("Sito"),boldFormat);
m_cursor.movePosition(QTextCursor::EndOfBlock);
QPainter p;
int pw = printer->pageRect().width();
int ph =printer->pageRect().height();
p.begin(printer);
p.save();
m_document->adjustSize();
QTransform tra;
tra.scale(11,11);
p.setTransform(tra);
...
m_document->drawContents(&p,printer->paperRect());
p.restore();
p.end();
