Hmm. I guess it all depends on what you mean by: Un-able to print valid HTML using IE.
I assume that you mean you are trying to pass a web page from your browser into Acrobat (or are trying to use distiller) but I think this is ultimately a problem of formatting. Websites are designed to be displayed in web browsers and not necessarily in a PDF and since you are relying on an automatic process (Print --> PDF) there isn't much you can do,
AFAIK, since your PDF writer decides how the page will be rendered.
