..know *what*?  (O;

The system will simply up- or down-res your image file to fit your
selected print size...  The dpi (or more correctly ppi) will vary
accordingly.

If you mean what is the best the printer can actually achieve, probably
~300 ppi, given sufficient data of course..  Ask them, and find out how
little the average operator knows.

Kodak picture kiosk outputs at 300dpi. However, much like megapixels on
cameras, this figure is misleading. The kiosk prints using a thermal dye
transfer which is not as good quality as a 300dpi print produced on a
Fujifilm Frontier or similar machine that projects the image on to
photographic paper.
