Different papers have different color profiles, different thicknesses,  
different resolution limits and different "ink load" limits, so  
theoretically all of these could be controlled by choice of paper.

By controlling color with the printing program you eliminate the first  
of these as an issue. (This is what you do with profiling systems.)

The Epson printers I have tried (C80/84/86/88 R220/1800 2200) seem to  
handle paper thickness either manually or by some sort of (unreliable)  
sensing system independent of the firmware, so that probably isn't a  
concern either.

Different paper choices using the Epson drivers often gives you  
different resolution possibilities. When I print on a good matte paper  
I have to choose some non-matte paper setting if I want 2880 dpi.

That leaves only control over the maximum amount of ink the paper can  
use. I do not know whether choice of paper actually controls this, but  
if it does you can usually override it to achieve a good print.  I try  
to make choices as close to high quality matte surfaces as possible,  
since these seem to absorb more ink than glossy surfaces. If it turns  
out to be too heavy on the ink you can back off pretty easily.

When I do not let the printer control colour, I have never seen any  
significant difference between different paper settings, at least on  
the 2200 and R1800.

More advanced printers -- e.g. the 4880 -- might adjust for paper  
thickness according to your choice, too, although I don't have any  
experience with them.  Those with better color vision might see  
difference, though!
