A de-rotation system includes a first ring gear defined about an axis of rotation, a second ring gear defined about the axis of rotation and a gear set in meshing engagement with the first ring gear and the second ring gear to control a position of a housing about the axis of rotation. In some embodiments, a programmable keeper circuit is coupled to a register file circuit. Preferably, at initiation of the forms mode at least the first listed document is immediately prepared by the control data processor of the printer in bit mapped form for printing. The computing system may provide a widget that displays, based on the map and the widget template, data from the data source. An application thus has substantial flexibility in defining and implementing custom authorization policy, and at the same time provides standard definitions for such dynamic data and policy.
