Hi there and welcome
Page 57 deals with this
It has 4 settings, L (Large) for 4000x3000
And S (Small) 640x480
It does not use DPI (this is what printers use) but this is how the camera refers to print quality
the numbers represent pixels.
You can see the manual online here
If you would like any additional information or assistance, please do not hesitate to let me know.
