There are good reasons to put some of Mike Chaney's facts 
next to the simplicity of the above message:

http://www.steves-digicams.com/techcorner/january_2006.html

and more of his contributions on the pages there and on the 
ddisoftware site.

Not so long ago I tested the downsampling of the HP Z3100 
driver and the downsampling of Qimage with its 
anti-aliasing, in the last case feeding the Z3100 driver 
with the native resolution. That tells a lot about what can 
be improved on extrapolation in drivers. There has been 
improvement but not on all aspects.
