The Kodak 6850 is likely supported, but needs testing.
This backend supports additional commands:
kodak6800_print [command [arg] ]
Valid commands:
-qtc filename Query tone curve [1]
Notes:
[1] Format of curvedata file:
256 entries each of Yellow, Magenta, Cyan mappings:
Values are unsigned 16-bit big endian, between 0 and 2047
(ie 11-bit)
