Just for reference, the 'ditto' device has a similar connector on the back and can be chained with a printer, but I have been printing with the printer (under Win95) and attempted to use the Ditto and the printer just starting spilling garbage all over the page. I would wonder how important that part of the Iomega design specs were for these drives (tape devices are 'special use' of course, but...)
