Well, this is what imaging-resource.com says on output quality:

S9500:
The Fujifilm FinePix S9000 produced very crisp-looking 13x19 inch prints on our i9900 printer. We've observed in the past that Fuji's SuperCCD sensor technology really shines in printed output, more so than when viewed on-screen, and the S9000 once again proves that out. Even 13x19 inch prints stood up very well to close inspection, appearing sharper than we'd normally expect 9-megapixel prints to look when printed at that size.
As noted above, the S9000 does fine at lower ISO settings, but its image quality degrades fairly rapidly above ISO 400. ISO 800 shots will probably be usable as 8x10 inch prints for most folks interested in displaying them on a wall or table, where they won't be scrutinized too closely. At 5x7 inches, ISO 800 shots are still a bit grainy, but should be satisfactory for most users. At ISO 1600 though, the noise is so high that the resulting images really shouldn't be considered for use printed any larger than 4x6 inches, and even there the color balance of the images may shift due to the large amount of blue-channel noise.

EOS350D:
Excellent prints at 13x19 inches and larger. (Some sharpening in the computer helps though.) Very low noise, ISO 1600 shots look good even at 13x19. Testing hundreds of digital cameras, we've found that you can only tell just so much about a camera's image quality by viewing its images on-screen. Ultimately, there's no substitute for printing a lot of images and examining them closely. For this reason, we now routinely print sample images from the cameras we test on our Canon i9900 studio printer, and on the Canon iP5000 here in the office. (See our Canon i9900 review for details on that model.) Prints from the Rebel XT look just beautiful at the 13x19 inch maximum paper size on our i9900, and judging from how clean they appeared at that size, could be blown up a fair bit larger and still hold together quite nicely. Like many Canon cameras, the in-camera sharpening of the XT is rather conservative (a wise approach that insures no detail is lost to overzealous sharpening), but the result is that its images have a bit of a soft look straight from the camera. A little work in Photoshop(tm) crisps things up nicely though, revealing an amazing level of detail. The harshest tests of print size re always high-ISO shots, but here again the XT came through with flying colors. ISO 1600 shots printed at 13x19 were noticeably grainy, but with most subjects (and viewers), you won't really be able to see it at viewing distances greater than about 18 inches or so. Printed at 8x10, ISO 1600 noise just won't be an issue at all, for any but the most extreme anti-noise fanatics. A very impressive performance. '
