Isn’t that simply solved with the right CSS? Clearing all floats should do the job as far as I know. I do agree that printerfriendly pages do not have to look/feel the same as their digital counterparts, but I’d personally stick to the easiest option, which is making my current style printer friendly, but indeed, that could be done without floating.
The biggest issue I’ve seen with printer friendly CSS is in the use of floats getting chopped if they extend beyond the page.

Hi,
these days I’m evaluating the MODx CMS in deep for a forthcoming web project. No doubt it’s a great app but, in my opinion, you should rethink some important choices. Here are some guidelines you could follow:
1. Less is more. MODx admin interface should be more clean and organized. Moreover the project website should eliminate any hype or buzzword and focuse on documentation and support. An updated list of MODx powered web sites should be added. Don’t forget that the best promotion for a web app is made by its happy users on their blogs.
2. The whole hyerarchy thing is simply old school. Instead you should introduce the concept of "section" and eventually "subsection". Each post should belong to a section (or sub-section). Home page should be a section apart. Friendly URLs should be mapped on the schema section/(subsection)/articletitle. So you could eliminate the archaic and ambiguous folder/file tree at left in the admin panel.
3. Each section should be associated with 2 templates: the first for the section home page, the second for the single entries. Of course two different sections could even share the same templates. Moreover, when posting an article, the user could choice a different template for that particular entry.
4. Template Variables should be tied to one or more sections not to templates. TV are related to data structure not presentation.
5. You should eliminate any embedded visitors logging. It suck!
6. You should eliminate frames (and the ugly file tree at left) in the admin interface.
I hope my suggestion can inspire the excellent dev team. MODx is not yet ready for my forthcoming project but I hope 2007 can be his year.

Hm, why bother about Web 3.0 when 4.0Alpha is just around the corner? But seriously, I don’t like those buzzwords, perhaps you can be more exact about your ’stuff that w3c recommends and plans to embed in the next 10 years’, because I certainly couldn’t find it.
:: ONE BIG CRITICS ONLY ::
Please add much more semantic. I mean that stuff w3c recommends and plans to embed in web3.0 in the next 10 years
like Tim Berners-Lee said. Semantic "should" (that word doesn’t sound nice lets call it "would be nice to") be generated automatically where possible.
