Printing from Heron on a Canon Pixma iP4200. Used to work fine, but now I get a major dithering problem. The image on the photo paper is extremely dithered to the point of looking like an old printer, not the fancy 600 DPI printer I have now. Any ideas on why this is happening all of a sudden? I have experimented with different dithering algorithms in the gutenprint advanced output options. They all look about the same. Some worse than others. Nothing at all like a photo should look on this printer.
