Prince converts Web pages into PDFs, intended for printing. The cave descriptions on this site can be printed using your normal Web browser, but if you use Prince, you can also get a nicely formatted table of contents.
Download Prince 6 or later for your system from the Prince 6 download page. Follow their instructions for installing it. Note that since this is for personal private use, it is free, and you do not need to purchase a license.
Tell Prince to load and convert the online page, as well as applying the special Prince stylesheet:
"C:\Program Files\Prince\Engine\bin\prince" --no-embed-fonts --style=http://www.cavinguk.co.uk/styles/prince-a4.css "http://www.cavinguk.co.uk/info/Crescent.htm" C:\description.pdf
prince --no-embed-fonts --style=http://www.cavinguk.co.uk/styles/prince-a4.css http://www.cavinguk.co.uk/info/Crescent.htm ~/description.pdf
You should now have a new PDF file in the specified folder (C:\description.pdf on Windows, ~/description.pdf on Linux/Mac). Double click it (or whatever) to open it in your chosen PDF viewer, and then use that program's print function to print it.
By default, it will produce a PDF optimised for A4 paper size, and most PDF viewers can zoom it to fit the paper if you use a different size in your printer. You can also choose these alternative stylesheets (as the value of the --style option) for different paper sizes:
