I'm looking at the Canon MP510, this would be for scanning in years of old photos and printing new digital pictures. This is just amateur home photos and I don't want to spend a fortune, but I do want good quality. I'm actually more concerned about the scanning, I think lots of current printers would be acceptable to me for photos of my kids, but I don't know where the line is on scanning. Are 1200 x 2400-dpi scans good enough or noticeably inferior to 2400 x 4800-dpi ? Is it like a camera megapixel issue where past a certain point the need for more becomes specialized to higher end users? Is it necessary to get a scanner that scans negatives for really good results or is scanning prints sufficient? Thanks for your input.
