Smart 2-to-a-page printing, without huge borders. Possible?

Question

I just poseted this in the feedback box, but maybe I should ask here too... does anyone know of a way to do smart two-up printing in OS X? By smart I mean that I want to print just the text, with the borders trimmed off, so that the text doesn't become impossibly small.
Any ideas? The closest thing I found was a program called BookLightning, which doesn't do this.

Summary: I'd like something like http://www.fineprint.com/, a
windows print-previewer that does smart 2-up printing, to
come with OS X.
I'm a theoretical physicist, and we all print out a fairly large number of research papers. While some use all the paper quite well, many have large text and larger margins. This produces good readability, short line lengths and all that, but is wasteful of paper.
I'd like to print them two pages per side, but if I do this using the printer dialogue box the results are often too small to be readable. The probelm is worse on letter paper than on A4. (Sometimes I can make it a little better by adjusting the scaling to 120% or so before printing, but it's hard to guess, and with letter paper this still doesn't let me use all the paper.)
In windows I had a program called FinePrint, which pretended to be a printer driver. Printing to it produced a window showing a preview of your document printed two-up (or 4-up, or as a booklet). The clever part is that it could be set to crop the document down to just the text, and then add margins of your choosing. The resulting printed text was often not all that much smaller than the original document's.
I can't imagine that this would be difficult to implement in OS X, everything is already PDF based so should scale well, and copping PDFs to a bounding box in LaTeX seems to work without a hitch.
Another feature FinePrint has, less important but also worthwhile, is the ability to print several document to it in sucession, and then print these as one print job. So scattered web pages or emails on a common theme, which would normally need a page each, could be printed two-up or double-sided.
I think this sort of functionality should be the default on all computers, I can't imagine there would be many such small steps that would save so much paper. But I'd settle for it just being an option.

Ok, first of all you have to find the menu element that muse generate. In the example you provided is #menu1564, but it could be different in the final output. Use a tool like firebug (Firefox extension) to easy detect your menu element.
Then delete the css rules "margin-left" and "left". Add the css rule "margin" and set it to "0 auto". (see the screen shoots i provided).
Now you must have the desired effect. I upload two more screenshot of the page in a medium and small browser size. You can see that now the menu remains aligned to the contents.
