--"We should probably put one qualification on that. A digital image will not degrade as long as it is saved in a lossless format (e.g., TIF). If you save as a JPG, keep in mind that JPG is a lossy format, and each time you resave an image in JPG, it gets slightly worse."--
Jpgs or any file won't "degrade" by being transfered to a new storage medium in the future. This would only happen if you re-edited and re-compressed the image. Theoretically with the same printer, color management and file(or a copy), you should be able to make an identical print in the future.
