There is also RTF::Writer, if the suggestion in Krambambulis link doesn't appeal to you.

"just generate HTML that of course displayed on screen"

What do you mean, did you see the raw html instead or did you see a correct web page as expected? In the latter case that is all you need, just create a link to the doc-file and the browser will give you the option to download it when you click on the link

You do know that you need a browser to look at your html-page, right? And if you want others to access that html page from other computers you need a web server like apache.

If this doesn't help, please tell us what your problem is exactly.
