Currently in Acrobat Pro DC, the only the way to center the image on a selected page size is to also select Auto for the page Orientation; Landscape or Portrait orientations both place the image in the upper left corner and there doesn't seem to be any way around this.

There are times when it would be helpful to be able to simply click a check box that will center the image on a selected page orientation (or, ideally, other options as well center top, center left, etc). Printing a square image (which is regarded by Acrobat as portrait) on a landscape page orientation is one such example that is currently problematic.

The best example of what I'd recommend is the Placement option within the Adobe Illustrator print dialog box.

Thank You for considering my suggestion!
