Kodak 605 works!
The Kodak 605 Photo Printer is their replacement for their earlier 68x0 series. And, true to form, it's incompatible with everything that came before.
Last night, I commited a backend for the Kodak 605 photo printer. Tonight, the last of the known bugs were fixed, and it appears to work!
Yay, that just leaves most of the Mitsubishi models (CP3020D/DA, CP-D70/707, CP-D9550/9600) that need testing/validating, plus whatever else comes along in the mean time.
