How can I give jQuery pagination a 'single-page-view' option?
I'm using this jQuery pagination script (http://bit.ly/enavujpag) to break up long articles into chunks with a navigation menu of "previous-1-2-3-next". I'd like to add an option that allows someone to click to view the whole article in case they don't want to click through each chunk, or want a print preview. The NY Times does this on long articles, for example, though their "Single Page" link is separate from the "prev-next" menu (which would be OK with me). Can someone add a single-page or print-preview option that displays all of the text of an article? Code attached or from demo at:

I'd also be willing to use this plugin instead if it's easier to configure:

Thanks!
