I also have a 9500 mkII. Good print quality, but you are stuck with the 35mm boarders anytime you use one of the Fine Art paper settings. This covers most of the better matte papers. Some paper companies such as Moab have made profiles that avoid the wide margins by using a different paper type. I have tried printing on Moab's Entrada and Lasal papers with the fine art profile and the small margins profile. While solving the margin problem the small margin prints are not as rich. You could also have custom profiles made to try to get good results with small margins.
I have just decided this is Canon's way of helping to reduce my ink costs by making my prints smaller.
