You are right; Qt Widgets are not completely compatible with HTML4. It only supports a subset of HTML4.
If you want full HTML5 compatibility, consider the Qt WebEngine: https://doc.qt.io/qt-5/qtwebengine-index.html (Note: This is a heavyweight web engine; if you use it, be sure to subscribe to security advisories and patch your app as soon as a security patch is released)

The first link was a reference document that tells you all the tags that are supported.
If you want examples, search your Qt Creator IDE's Examples section. Use "rich text" as your keyword. See https://doc.qt.io/qt-5/examples-richtext.html

I need HTML examples, not rich text
The rich text examples are HTML4 examples.

@duncan98 I suggest you first take a look at HTML documentation: https://www.w3schools.com/html/

What is this mess
You claimed that the rich text examples don't use HTML.
I showed you that the Text Edit Rich Text example uses HTML.

I know standard HTML, but qt HTML is very confusingI have done HTML for many, many years, so I know it too. What is your actual issue with the subset of HTML supported by Qt, e.g. in a
QTextEdit?You can copy the whole of the HTML content from the https://code.qt.io/cgit/qt/qtbase.git/tree/examples/widgets/richtext/textedit/example.html?h=5.14 example you refer to as a "mess", and as well as pasting it into a
QTextEditto look at it you can also save it to an.htmlfile and open it in your web browser. Since it looks pretty similar there, you know it must be reasonably close to HTML. You can use the browser's F12 or your favorite HTML editor to examine the HTML. -

What is your question? You can print from aQTextDocument. It supports precisely the HTML subset we have referenced above. If your content fits into that subset it will work, if your content goes beyond that into non-supported HTML constructs it will not (probably just ignore them). That's just how it is.If you want full HTML support you would need to move to using
QtWebEngine. You can print from there too, which would then support full HTML. You can arrange for the content of aQTextDocumentto go into aQWebEnginePageif desired. But your originalQTextDocumentis still liable to be limited to the Qt-supported richtext-HTML subset. -
