There is now documentation you can download, read offline and print !
Over at http://www.tamba2.org.uk/wordpress/docs are listed over 240 complete pages (a total of ~34meg of information) taken verbatim from Codex. You can download just those sections you need – and none that you do not.
Before you start downloading or commenting though, please take a moment to read the information Iâ€™ve put together here: http://www.tamba2.org.uk/T2/codex-and-pdf/
It should address what I think will be common questions.
Once Codex is back, the management and direction of this project will be taken to there with additional input from the WordPress Docs mailing list.
