Can the Pro 10 Print images longer than 19". Has anyone done so?

It looks like customs setting allow this, but I don't want to waste the ink and canvas for a 12x24 if it is going to stop at 19".

I think it can do 23" in the custom print size.  I had a friend that told me she printed a 25" length but personaly I never tried to.
