Thank you.
2000x3000 pixels on a A4 paper is approx 250 dpi, which is fairly good.
On a A3 paper, it would be approx. 160 dpi...
Interpolate Patrice, interpolate. I convert my RAW *ist D images to 11 x 17 360
dpi files for printing. The upsized files yield far nicer prints than does a
native resolution file.

Yeah, of course, you don't want ugly square pixels all over the place.
But even with interpolation, you won't get as much detail with a source
image that yields 160 dpi as with a source image that yields 250 dpi
(provided that the lens is up to it, of course, and that the file holds
a sharp image in the first place).
I've made some real-life comparison with various
enlargements/interpolation combinations, and I also found out that one
gets much better results using Photoshop's interpolation than printer
drivers can do.
There are very high quality interpolators that can do an amazing job at
enlarging prints with very good results at large ratios, too.
