I understand what you mean. If we are still talking in the context of Evince, the "Landscape" and "Portrait" options are handled by Cairo, not CUPS. If you select "Landscape", Cairo rotates *every" page in the PDF by 90 degrees if the page width is *less* than the height. If you had a 842x595 sized pages they would not be rotated. Effectively, the option does nothing. Or rather - it doesn't do what you think it does. But (you say). the printout is OK. That's because you have the "Auto Rotate and Centre" option ticked. Nothing to do with "Landscape" selected. Even if you forgot to tick "Auto Rotate and Centre" and sent a 842x595 page to the printer it will still be printed correctly because the pdftopdf filter of cups-filters automatically rotates landscape pages by 90 degrees before printing. -- Brian.
