Digital BW, The Print

I have not been any more impressed with Genuine Fractals than any 
other iterpolation scheme... others swear by it...

If your driver does use nearest neighbor interpolation you *should* 
gain a lot by upsampling yourself.  Image Print uses bicubic.  Don't 
know exactly what Canon or Epson uses.  I have not seen any noticable 
improvement upsampling before sending images to my 1160... but I 
haven't spent that much time testing it since I am generally happy 
with what I get and managing huge files isn't much fun on my 3 year 
old computer.

The main advantage that I can see to upsampling before printing is 
that you get a chance to sharpen your interpolated image and then 
more or less print exactly what you send your printer instead of 
letting the driver do it's magic.

Here is a sales pitch from QImage that seems compelling:

but even using their software, my friend can't really show any *real 
world* proof that you will get better prints using this technique.

No interpolation scheme is going to be *better* for all images and 
all higher order interpolation schemes *soften* your image.
