Abstract
A bound booklet is opened and inserted into a guide. A platen, having individual spring biased segments, is positioned against the booklet covers while printing means move horizontally across the open pages of the booklet. A first platen segment contacts the front cover of the open booklet, while a second segment contacts the back cover. An intermediate shortened segment yields to the binding edge of the booklet. Thus, the varying thickness of the booklet is compensated for and a flat printing plane is presented to the printing means. A single leaf document may be accommodated, instead of a booklet. In the case of a single leaf, the resilient nature of the platen compensates for single leaf documents of different thickness, within a permissible range.
