So I designed my book cover in Adobe InDesign, and I have 9×12″ sheet of cardboard. My issue is that when I try to print it out, it is either in the wrong direction, wrong size, or both! How can I print it out in the correct size in the correct direction?

By the way, the cover from edge-to-edge is 7.5″ by 5.25″.

Thank you for any help you can provide.
