Abstract
A method and apparatus using a duplex printer to print indicia on the back side of a printed page to provide privacy for confidential information appearing on the front side and/or indicia to indicate that information which previously appeared on the back side of a printed sheet is not relevant to the information appearing on the front side of the printed sheet.
Claims7
An image forming device for printing automated duplex images which comprises:
- a housing;
- a print engine within the housing;
- a printer controller operatively connected and in communication with the print engine;
- and
- a formatter operatively connected to the printer controller, the formatter being configured to detect a duplex image flag and generate a duplex image of obscuring graphics in a mirror of a privacy zone, to be printed on a second side of a sheet of media.
A method for forming a duplex image using an image forming device, the method comprising the acts of:
- generating privacy zones demarcating confidential information within an image to be printed on a first side of a sheet of media;
- mapping the privacy zones in mirror image fashion to a second side of the media sheet defining mirror image privacy zones;
- and
- filling the mirror image privacy zones with obscuring indicia.
A method for forming a duplex image using an image forming device, the method comprising the acts of:
- differentiating a relevant area of a sheet of media from an irrelevant area:
- setting a strike-out flag to indicate the irrelevant area of the sheet of media;
- generating an image to be printed over printed information on the irrelevant area of the media;
- and
- printing the image on the irrelevant area of the media.
