ancestry I think the Imagewriter 1 was just a rebadged C. Itoh 8510. One of the C.Itoh models supported a 4 color ribbon. and this carried over to the IW2. The ancestry of the IBM Color printer goes back to the IDS 480 which was such a nice printer that Dataproducts bought the company in the very early 80s. I believe its design became the basis for the long running Dataproducts 8050/8070 series of dot matrix printers offering color ribbons. I think the IBM Color Printer was made by Dataproducts with different plastic and branding. Paxton Hoag Astoria, OR USA
