native resolution of printers?

Hi all,

I had an Epson Photo 700 and as far as I knew, the native resolution was 360dpi.

I now have a Canon i9950 and was wondering what the native resolution is,
because i've heard that if you send your images to the printer at it's native
resolution, it won't stuff up when it scales the image to the printing
resolution (eg 4800dpi or otherwise).

So how do I find out the native resolution of my printer? canon.com doesn't seem
to have the info.
