Abstract
An environmentally insensitive device is described. The device uses a passive paper guide to direct an output paper stream from a paper source contained within the unit to an output aperture. The passive paper guide uses two opposing surfaces to define a radius of curvature through which the paper strip is guided. Use of longitudinal ridges along one or both of the surfaces reduces friction along the guide. By providing a rotatable output cover over the aperture and using a unit cover, a printed output can be achieved while maintaining the shielding of the unit from environmental effects.
