I have a new 9880.
What it needs it a cutter built into it that will cut canvas and stocks of similar weight. These are popular papers and should be accommodated.
It also needs to replicate the ImagePrint Phatte Black system so there is NO line purging at all. Even 4m every time is not satisfactory when it is being done with 0m waste.
As far as quality goes, whatever they can do to make it better will icing on the cake. The prints I am getting out of the printer is better than any film and lab days prints I have ever gotten. And I am only using Qimage instead of a rip, so I am very very pleased at the level of quality coming out the front end of this thing.
Speed would be a point to improve on too. This is supposed to be faster than the older units, it makes me wonder how much slower the older units really are. Something to think about.
