Hi Travel_guy, and a warm welcome to the forums! 🙂
My D7460 drove me crazy too, you have to start a Print with CMD+p or whatever, click on the 3rd drop down menu that says Copies & Pages, choose Paper handling, then Destination Paper Size... 4*6 or whatever, then go up to Presets & Save As..., give it a name... those settings will load automaticxally when you choose that Preset & Printer next time! 🙂
