What paper, profile, etc. Matte ink or photo ink. It appears you are printing off the image also, at least on the left edge of the shot.
I would suggest going back a step, and try a color test pattern, make one or there are several published on the web and see if you get the same error. Or just try a solid color. The carry over seems to be magenta and blue.
Has this happened before? and what software solution are you printing from? When this type of thing happens, I feel you have to back off to see where you can get a good print. It's a lot easier to trouble shoot from a simple test image, if that works, then slowly work back to the image at hand.
Going back to your images, it's almost like the ink is bleeding over during the print, and that may point to the inkjet receptor coating. That's why I asked the paper being used. If it's just traditional watercolor paper, you may not be able to use it as it does not have a proper coating.
All your checks point to a printer working fine within it's limits.
