We introduce Imprint, a casual information visualization system that showcases data extracted from a printer queue. The system filters and aggregates data including layout information, text, and images, and displays interactive visualizations on a large touch-screen display mounted above the physical printers that serve a small community. Imprint’s visualizations depict environmental issues, such as energy consumption and paper consumption of the printers, as well as social information, such as popular concepts from the printed matter. Imprint is intended to spark reflection and conversation, and to bring data into discussions about paper usage,“waste,” and extrapolation. The goal is not to explicitly reduce paper, energy, or toner usage, but instead to open some of the very questions that might, for example, cleanly delineate what counts as waste when it comes to the printers as they are being used by the community. We note an emerging list of design strategies that have helped us to explore these issues. The first we term “eating the dog food,” or walking the walk—when a visualization brings up environmental impact data it must also disclose how much environmental impact the system itself produces as it operates. Others may follow, including the use of defamiliarization, and the use of social particulars in visualizations.
