When my CMYK photos were printing with weird colors, I tried printing just a square of 100% magenta. It came out looking like about 75-85% magenta with quite a bit of yellow and some black or cyan. It looks like Jakobud's image has extra magenta added to cyan where there was none in her/his document. What the heck? My photos are coming out with extra yellow and not enough magenta, just like my magenta square. I don't see a way to access the driver, other than through ColorSync, and I wouldn't know what to do there.
Test prints from the printer utility come out perfect, and I just bought new Canon cartridges, because I thought maybe my cartrides had a problem.
I already spent hours figuring out that it won't print any black if you choose "Photo paper Glossy" under "media" and now this - ugh!
I have the MP280 and am on a Mac running OSX 10.6.8
