You will need a web rendering engine to consume the input and execute the script accordingly, then let it print the result.
For example using QWebEnginePage and one if its printToPdf() functions.

See this stack question: QWebEngine: print a page?
You will find the correct way to print a webview by using new engine based in Chromium or the older webkit. The two options are completly compatible with Qt Quick.
You also could use a QTextView to print the data by loading the HTML inside.
