QTextDocument do not support all HTML features - only limited HTML subset, so you can do one of following:
- Try to intuitively optimize your HTML code for QTextDocument: layout page elements using tables instead of divs, etc.
- Print HTML with QWebView::print method (QtWebKit module)
- Print HTML with QWebEnginePage::print method (QtWebEngine module) - only for Qt 5.8
Unfortunately, QtWebKit module was removed in Qt 5.6 and QWebEnginePage::print method was added only in Qt 5.8, so par.1 and par.2 cannot simply be used in Qt 5.6 & 5.7
