since I have an iMac my photos showed a severe banding especially in the sky area. I don't mean it's a Mac problem, but probably the driver I have is not properly optimized. It happened since the beginning (Snow Leopard) and with a Canon Pixma iP4500 and continues now days with Mountain Lion and a new Canon Pixma iP4900 I bought because blamed the 4500 to be arrived at the end of its life.

Of course looked for most recent drivers. I usually do print using Canon Easy Photoprint EX and never had a single problem in Windows environment: always got brilliant results and that's why got a second Canon. Any hint?

Thanks, Gianfranco

    probably the driver I have is not properly optimized.

    You could be right, but also check nozzle cleaning (and quality of the whatever ink cartridges you use - could they be drying up from lack of use?).


    And of course: is the driver up to date?

    Thanks, the driver was updated, but for a strange reason the printer continued to print without any warning, but opening the cover both cyan and magent were flashing. After replacement printouts were ok.

    I will investigate sending a mail to Canon support.

    Thanks, Gianfranco
