I'm trying to print out some photos that I took on my digital camera. They look great on the computer screen, but when I print they come out pixely. What gives? I've printed pictures that I've scanned and they look fine; so, I don't think it's the printer. What do I need to change to fix it? I am using Fireworks to edit the pics, printing on an HP and my camera is a Nikon Cool Pics.
