I would suggest staying the hell away from jpeg if you have any intention of making a print (or any other reproduction...or in general). Jpeg is a lossy format, which means that every time you save as a jpeg the compression throws away data. If you were to save the modified jpeg as a tiff, png, or any other lossless format, you wouldn't lose any information and could (in theory) get away with it.
