Also “not to self-promote”, but my Inside TiddlyWiki — A Guide for Users, Authors, Designers and Developers already produces “printer-ready” output, suitable for using “save as PDF” to create a stand-alone PDF file. Just click the “print entire book” icon in the upper-left toolbar. This will open a separate “Inside TiddlyWiki - Print Preview” window.
Then, from that window, click the printer icon in the upper-right corner. This will trigger your system-based print dialog, with proper application of the page-break:after;
CSS attribute so that each logical “book page” will be printed on a separate piece of paper (with overflow to additional printed pages as needed for longer content). There are currently 95 book pages generated by the print output.
In the options provided by the Windows system-based print dialog, you can then select a destination of “save as PDF” to create a stand-alone PDF file. I would guess that other platforms (e.g., Apple or Unix) probably have similar system-based print options as well.
enjoy,
