I find 180 to 200 ppi produces very satisfactory rendering quality  
for A3 and A3 Super sized prints. A K10D body produces full-frame  
image with 2592x3872 pixels, which means a 180 ppi density print  
covers 14.5 x 21.5 inch image area, without upsampling or other  
interpolation.

If more print output density or a larger print is desirable, you  
upsample either in the RAW conversion processing or in post  
processing. You get no more detail but the rendering is usually  
smoother.
