Yes, but I ment printing with canons print menu 'My image garden'. If i do as suggested it print as a non script printer. There is a world of difference in the quality of print. What really is the matter is that aperture does not appear in The 'My image garden menu' though iPhoto and pictures folder does?
Sorry that I cannot be more helpful, but I do not have that software or printer. I don't see why all the capabilities of the printer cannot be available to printing in Aperture, if the latest driver, and color profiles are installed?
For seeing the Aperture Library as you do iPhoto, have you set in Aperture Preferences to automatically generate and share Previews? If you are doing this from the iPhoto Library, then you are printing from Previews and not the full size image file.
