On systems with CUPS support users can now choose how many pages from
a document are to be printed on paper. This can vary from 1 page per
document to 16 pages per document.

The page preview changes upon the users selection.

Also included in the patch is an option to choose the flow for text.
Users
can now print documents in the "Right to Left" order or "Bottom to Top",
including many other options.
