Prevent page break inside a div

[bluemmb]

Hi , i have used this code for printing a text in pdf file :

QString pdf = "<div>...</div><div>...</div>....";

QTextDocument doc;
    doc.setHtml( pdf );
    QPrinter printer;
    printer.setOutputFileName( FileName );
    printer.setOutputFormat(QPrinter::PdfFormat);
    doc.print(&printer);
    printer.newPage();

Actually I have some divs and i don't want to pdf creator break pages inside of each of them . I tried " @media print { div { page-break-inside:avoid; } } " but it does not work. How can I do it ?
