Abstract
The invented sheet media marking system provides a platen which is configured to rotate a sheet of medium about a marker so as to accommodate marking of the sheet. The platen preferably takes the form of a rotatable drum, the interior of which supports the sheet at a predetermined distance from the printhead which is suspended within the drum. A printhead support is used to hold the printhead in a fixed rotational orientation relative to the platen's axis of rotation, each rotation passing the sheet across the printhead for marking thereof in a swath of print. The sheet is advanced using a medium advancing mechanism which directs movement of the sheet along the interior surface of the drum.
