I added my thoughts on this in another similar thread a few months ago: see post #

Simply stated, Media Center IS NOT the "one stop" media shop that MSFT positions it as.
So, for those people who wish to print high quality photos, my suggestion is to do it OUTSIDE
of the Media Center interface.
I also think that since it's easy enough to print outside of Media Center, it's to everyone's advantage
not to burden the Ehome team with this and to save the feature requests for the really important
stuff.
Just my .02, YMMV
