what do you mean some of the units do not print discs? are you refering to pigment inks when you said that? why didn't epson think of this before putting dvd printers on those models?
and im not using the printer just for the discs, if i can pull a decent photo printer/scanner out of the deal at the same time that would be pretty sweet.
and im guessing the lack of high res printing is due to the dull printable surfaces on the discs?
