I have a Pixma pro 10 printer. I use an Apple computer and my pictures are in iphoto. When I print a picture out lately they are very dark. I have talked to Apple and to Canon and still having the problem. I know that the picture i see on the computer and the one I print are not going to be exactly the same, but these are way off. Any ideas?
Have you tried a nozzle check and cleaning?
Can you reprint a photo that printed well before and see what happens?
To be clear:
1. you are using the same photo processing software and computer operating system as before (when it worked well)?
2. you haven't updated either the OS or the photo software between then and now?
