You would not have seen this result if you had compared your JPEG images with image formats like GIF or PNG, but at adequate resolution (say, 600 dpi). That would have made for _huge_ GIFs perhaps, but you'd have seen excellent results. Basically, it's not the file format, but the resolution. The reason you're seeing this is because JPEG being lossy, can be uncompressed to any size using a complex mathematical function. The uncompressed image does not have to be the same size as the original image which was compressed to create the JPEG. The mathematical decompression algo is smart enough to do a fairly smooth scaling up, hence you see acceptable print quality even though you're probably printing 100 times as many pixels as there were in the original source. GIFs don't get the benefit of any such smart scaleups, so you see pixellation.
