Coming to this thread a bit late, but I've got the original HP files for the digital negatives if anyone still needs them. I've played with this several times and not gotten it to work correctly, but really want to for both analog silver prints and also platinum palladium prints. I've e-mailed with Angel a few times but somehow am still missing something. It's probably very simple in getting the files to print with the green and black inks together.
I'm curious to hear from people that do get this to work on the Z3200 what transparency media they are using and how they are sending the files to the printer.
