Some fine modes of the 4000-7600-9600 Epson drivers have 720 PPI native 
resolution as well so I expect the same for the 4800.

With Qimage I do not worry what I send to the printer. The file can be 
kept in its original (scan) format and the up or down sampling to the 
driver's native resolution is done well with Qimage. If there's an 
overload of information: 6x6 or 6x9 scanned at 4000 PPI and used for (a 
series of) a small print(s) then I tend to do a downsample to 360 PPI as 
otherwise it takes much more time in processing, Qimage's interpolation 
etc settings on "off" then. That file goes in the dustbin afterwards.
