I had the same result a several years ago and stopped adjusting images
to a magic dpi before printing. Bicubic was the best interpolator that
I had at the time. The Epson diffusion dithering seems to hide most
interpolation artifacts in normal photo images.  The entire issue went
away when I switched to Qimage printing.

You might see more of a difference with one of the fancy interpolation
+ print sharpening applications like QI.
