In a large 4-quart slow cooker sprayed with cooking spray, mix the macaroni, evaporated milk, milk, butter, salt, pepper, eggs and all but 1/2 cup of the grated cheese. Sprinkle the reserved cheese over the top of the mixture and then sprinkle with paprika. Cover and cook on low heat for 3 hours and 15 minutes. Turn off the slow cooker, stir the mixture and serve hot.
If you don't have a slow cooker, grease a 9-by-13-by-2-inch pan with butter, add the mixture and bake at 350 degrees F for 50 minutes.
