I am interested to hear about this Alan, for two reasons.

Firstly, I have used exactly the same equipment and have never 
experienced banding as a consequence of this approach which is, in fact, 
my normal mode of operation - adjust the print size and let the ppi fall 
where it may as long as it isn't higher than 720ppi.

Secondly, this should not result in banding, given the processes 
involved.  A non-integer ppi applies equally to the vertical as the 
horizontal axis, so any artefact of the rendering process should apply 
equally in either direction (excluding bugs).  Banding is an error that 
predominates in one direction over another, so it should not be a 
consequence of rendering from a non-integer resolution image.  Certainly 
you have more dots in the horizontal axis with most Epson printers, but 
that is the same no matter what resolution the image is, fractional or 
integer.

What driver version are you using?
