thanks for the tips,
but didn't help. I reinstalled from the canon-europe site, there is no MP560 in asia, the driver debs, but nothing helped. And I suppose, as the testpage looks colorfull and perfect, that the right driver is installed and there is a error in the communication between evince etc. and the printer.
Ahh I am using the printer via usb-cable...
