It seems simple to me.

You get the print driver to output the lightest continuous (yeah I know)
tone it is capable of short of not printing at all. You measure the
reflectance of that patch.

You measure the reflectance of the darkest tone it is capable of laying
down.

The dynamic range is the ratio between them, exactly as Kevin said.

I don't know why you're all making it so damn complicated.

Martin, if you think an inkjet print is a continuous tone, then for any
shade of gray which Kevin prints using his printer and claims to be the
lightest gray possible, you with your magic continuous printer, will be able
to print a lighter tone.

I shall be interested to hear how you intend to do this.
