Anyone know how to format a document for this sort of printing?

So, let’s say I have a 4-page Word document (which I do) that is formatted for standard 8.5X11 pages, but you want to print it off onto one single 11X17 sheet. Two pages on one side of the sheet, to on the other. More, you want it to print like magazine pages, so that the pages are not necessarily in sequence. So one side of the 11X17 would have Page 4 on the left, Page 1 on the right, the other side would have Page 2 on the left, Page 3 on the right. Of course longer files would add further complexity.

Anybody know how to accomplish this?
