All the links back to sellers on Amazon are dead, they have no product. A few sellers on eBay have individual ribbons. Iowa Computing and Supply Depot claim to have product. Several other vendors are mistakely claiming ribbons for the ImageWriter II, which takes a completely different ribbon. Cross referencing other mentioned ribbons and printers such as the C.ITOH 715 and Facit 3550 does not seem to produce any additional results.
A search for the part number A9G0335 (alone) turned up several pointers to "Ink Oasis", of which only this link appears to be relevant:
