A landscape-only application should support both landscape orientationsthat is, with the Home button on the right or on the left. If the device is already physically in a landscape orientation, a landscape-only application should launch in that orientation. Otherwise, a landscape-only application should launch in the orientation with the Home button on the right by default.

Preferrably you should support both orientations, and launch with the Home button on the right side if you don't support portrait mode. If you only support one landscape orientation, I would guess having the Home button on the right is the best option.
