Turn Web page into a PDF Document

HTML2PDF is a nifty little tool that converts any HTML webpage into a PDF document. See today’s WisBlawg in PDF for example.
I can imagine a few of uses for this tool: 1) To digitally archive a web page as it exists today; or 2) to capture a web page for an off-line presentation; 3) to get a clean print for those pages that don’t print correctly from your browser. Any other ideas?
