There is a "auto resize and center" option in the "Page Handling" tab which would center the pdf if its aspect ratio is different from the paper, otherwise it defaults to top-left I think.

I can't achieve that option with zathura's print dialog. Can this be supported? Or is there any workaround? Of source support it would be preferred :)
