When you print on a bordered layout, the margins on the left and right or the top and bottom may become wider than the other, depending on the image and printer.
To always print with even margins, select the Always crop images when selecting a layout with margins checkbox on the Advanced tab of the Preferences dialog box.
To display the Preferences dialog box, click 
(Settings) in the Layout/Print screen or select Preferences... from the File menu.
Crop the photo to apply even margins individually.
NoteThis setting is available only when Photo Print is selected.
