Thank you for your answers!!

When the ACPU didn't work I was able to print the charts with Canon photoshop print-plugin and the photoshop null-transfrom trick without any problems. So I was wondering, why ACPU didn't work.

I wrote a small test application, which couldn't deactivate the color managment of the ipf6300 too, until I had added the application name to the AppColorMatchingInfo.xml.
