paint driver for Shinko645 (4 color ribbons) ?

I wonder if someone have written a paint driver for the
Shinko 645 model. I started to look at the Shinko 635 driver
yesterday and thought that I could use it, but we realized that
some things may have to be changed.

The biggest problem for me is that the 635 driver is written for
3 color ribbon. We are using the 4 color ribbon version of the
645 model ( with black included ).
