Abstract: A printer with a chassis, a hinge and a paper cover assembly. The chassis may have a printing head and a notch. The hinge may have an axis, and may be coupled with the chassis such that the rotational axis of the hinge is laterally movable. The paper cover assembly may be coupled with the hinge, and may be rotatable about the hinge. The paper cover assembly may have a roller and a handle. The roller may have an axis, and when the paper cover assembly is closed, the axis of the roller may be within the notch. The handle may be configured to move a cam mechanism, and when the paper cover assembly is closed and the mechanism is moved, the mechanism may act against the chassis causing the axis of the hinge to laterally move, thereby causing the axis of the roller to move out of the notch.

Abstract: Various improved features for a point of sale (POS) device are disclosed. The POS device may have a housing, a document path, a check-voiding printer, and a door in the housing enabling access through the document path to the check-voiding printer. The POS device may have a connector and cavity in its interior, not visible from the exterior, the cavity configured to hold an accessory device connected to the connector. The POS device may comprise a read head for reading characters printed in magnetic ink on the face of a check and a biasing mechanism that has a contacting face that holds the check against the read head. The POS device may have an opening in a back wall through which a check is at least partially visible during reading. The POS device may include two microprocessor systems that control different parts of the POS device.
