METHOD AND APPARATUS FOR RANDOMIZED PRINTING AND BIDIRECTIONAL SHIFTING

摘要

Method and apparatus for the randomized printing of transactions or voting records using a printer with a paper roll supply where after one area is printed, the paper is randomly shifted either in a one or bidirectional fashion to another area not adjacent to the previously printed area thus removing a set print record order and preserving randomness in print. A motorized paper roller is used for bidirectional paper shifting, an optical sensor is used to check if an area of paper roll is available for printing by reading indicia, procedures are used to randomly move the paper roll to prevent printing in a continuous motion, and a supply roll casing includes adequate spacing within to support the return of the paper roll during bidirectional paper shifting without rewinding the supply roll.
