Print Orientation /Correct directly from DTPO?

Some items, JPG images for example, may be Landscape layout formatted. However, when trying to print direct from DTPO, they always print in Portrait mode (centred), which may not be preferred. It does not seem possible to fix that problem from within DTPO. So the files need to be opened in an external viewer first, for each and every print. Is there a way to include the print preferences, such as orientation, in the metadata?
