That's useful for some cases, but it's not a replacement. It'd be far
from trivial to accurately render a PDF to a painter surface, so
printToPdf can only be used in the limited case that you just require
an unchanged PDF output of HTML. If you want to render additional
content around the HTML then you're out of luck...
