Panoramic printing with i900D

[JoeBtfsplk]

Have thirty or so very long panoramic pix (from photostitch), and want to print them on 4" by 23" glossy paper (which I have hand-cut from a 4" roll). I had thought that I could do this with the i900D, since the "page setup" options allow me to choose paper size (up to 23" long) by selecting page size = custom, printer paper size = same as custom, and any of the various selectable "printing type" choices. However, rather than printing the picture, an error message comes up saying that "The following settings could not be maintained: Paper size."

I suppose that this indicates that the printer perceives some "page size" value associated with the jpg image.

Anybody have a solution for this?

Thanks,

Joe
