Web documents are cheaper and more accessible, but there's still a quite large usage of print documents, so at least I, as a document author, don't want to commit to a "web-only" toolchain without a good to-print workflow also being available. It's possible for HTML+CSS to also provide a good to-print workflow, but I don't think it's there yet, at least using open-source tools. I have heard PrinceXML can produce good results, with sufficient control over the print layout to make HTML+CSS usable as a print-oriented markup language. But between the cost, and the prospect of becoming dependent on a proprietary tool with no obvious alternatives, I haven't tried it.
