I am always amazed to read about compression in jpgs. This is not necessarily the case. Part of my job as graphic designer is to use images that i have to buy from professional image libraries. Or use images from libraries of clients (HP for example). Surprisingly they ALL come as jpgs - without ANY compression but very compact in terms of file size. We print them up to A0 (more than a meter high or wide) or use them in brochures. No problem at all. So this is not necessarily a problem of using the file format but of the options that people select.
