Sorry for entering a discussion long after it is over (I am just reading up on 2 weeks worth of mailing lists).
I have a script for the psutils stuff, which I use it for printing all sorts of documents as booklets (on duplex-capable printers) to save paper. Not rocket science, but it does a nice job, including - using the document bounding box for geometry calculations or even - determining the bounding box `experimentally', using ghostscript - works well with A4 and letter paper - inserts a duplex cookie into the postscript - can tumble the even pages even on stubborn printers. E.g. ps2book -Pdisplay -F0.87 <file.ps> will produce a booklet, scaling the true bounding box (of the first few pages) to <= 87% of the available space in width and height, and show you the result in gv. The script can be found at http://www.capca.ucalgary.ca/~wdobler/utils/ps2book.html I have used it for years, and it is well documented. If somebody tells me that this would be interesting for the Scribus+booklet wiki, I can insert a pointer there. W o l f g a n g
