Never heard of a Gocco print until now. It's an intriguing screen printing contraption with a build in photo emulsion system. I'd love to get my hands on one but I'll have to act quick. On May 30, 2008, the RisoKagaku Corporation announced that it will stop shipping Gocco printers in June 2008!
I've discovered that there is a Gocco print postcard call out to save the Gocco printer, see 'save gocco' for details, and check out The Wurst Gallery , featuring prints made exclusively with the Gocco printer.
