When I print a page with Image Quality -> Resolution at 300 dpi everything works fine, but when I print at Image Quality -> Resolution at 600 dpi everything prints twice as large as it ought to with resolution (I believe) at 300 dpi.  The page that's printed shows only the upper left quarter of the image that should be printed.  I've had this problem in the past (Fedora-15), but only with the Gimp and Gutenprint; now it happens all the time.
