HP Photosmart 6520 and Phtoshop Elements

Using my HP Photosmart 6520 with Photoshop elements 10, colors on the printed photo are different from those shown on the monitor.

Taking in account that:

- the monitor is calibrated with ColorMunki Display;

- PSE manages colors;

- printer's color management is disabled;

- color space is Adobe1998

Do you have any idea why the colors are different?

Thanks

Antonio
