The "Page Setup" tab of the print dialog allows zooming the document when printing. But this setting doesn't sound very useful, since the document is never centered on the page: contents are very likely to be truncated when reaching one of the page's sides.

Since the "Page Handling" tab has an "Auto Rotate and Center" option, I think the zoomed document should be centered when both options are checked. This would fix the truncation problem, and in particular would allow reducing document margins when you don't need/like them (this happens very often when printing academic papers).

Do you think this is a bug in Evince or in GTK?
