The color dye diffusion/dye sublimation printers I have looked at
(Kodak, NEC, and Hitachi) have all been bitmap (raster) image
printers. These devices are generally geared towards printing
24-plane true-color images, as they can produce a full 16.7 millon
color image without resorting to dithering techniques. Postscript
was designed as a textual page layout language, not as a 3D color
imaging language. As such, it is not real good at describing true
color images (at least, not is less space than a 24-plane color
bitmap would take). The model of the 4693D which Apollo was
initially selling was not the Postscript compatible model, it
was the straight raster bitmap printer. Unless they have begun
to support both the original model and the Postscript (aka. the
Phaser) model I don't think you could use Apollo's printer driver,
and my latest copy of the Apollo add-on products catalog only
lists the non-Postscript version of the printer.
