First Claim
Patent Images
1. A printer system for a record containing indicia on at least a portion thereof, the printer system comprising:
- input means for receiving information to be placed on to the record;
encoding means, coupled to the input means, for encoding the received information in an error-correctable, machine readable, two-dimensional bar code format; and
output means, coupled to the encoding means, for printing the received information on the record, the output means including means for removing encoded information other than the received information from the record, means for drying an area of the record underlying the removed information, and means for removably printing the received information on the record after removal of the other encoded information.

8. A printer system for a record containing indicia on at least a portion thereof, the printer system comprising:
-
input means for receiving information to be placed on to the record; encoding means, coupled to the input means, for encoding the received information in an error-correctable, machine readable, two-dimensional bar code format; and output means, coupled to the encoding means, for printing the received information on the record, the output means including means for removing encoded information other than the received information from the record, and means for removably printing the received information on the record after removal of the other encoded information; wherein the output means further includes; means for detecting the presence of the encoded information on the record; and means responsive to said detection means for rendering said removing means inactive at times when the record is without encoded information. - View Dependent Claims (9, 10, 11, 12, 13)

14. A printer system for a record containing indicia on at least a portion thereof, the printer system comprising:
-
input means for receiving information to be placed on to the record; encoding means, coupled to the input means, for encoding the received information in an error-correctable, machine readable, two-dimensional bar code format; and output means, coupled to the encoding means, for printing the received information on the record, the output means including means for removing encoded information other than the received information from the record, and means for removably printing the received information on the record after removal of the other encoded information; the means for encoding the received information in a two-dimensional bar code format includes a plurality of ordered, adjacent rows of codewords of bar-coded information from a set of codewords; the set of codewords is partitioned into at least three mutually exclusive clusters, each row in the two-dimensional bar code structure having at least one row indicator codeword and containing only codewords from a cluster different from the codewords in an adjacent row, and the row indicator codewords contain information regarding the number of rows in the two-dimensional bar code structure and the number of codewords in each row. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A printer system for a record containing machine readable indicia on at least a portion thereof, the printer system comprising:
-
input means for receiving information to be placed in machine readable format on the record; output means for printing currently received information on the record, the output means including means for removing previously printed information other than the currently received information from the record, and means for removably printing the currently received information on the record after removal of the previously printed information. - View Dependent Claims (23, 24, 25, 26)

27. A printer system for a record containing indicia on at least a portion thereof, the printer system comprising:
-
input means for receiving encoded information to be placed on to the record; and output means, for printing the received information on the record, the output means including means for removing encoded information other than the received encoded information from the record, and means for removable printing the received encoded information on the record after removal of the other encoded information; wherein the output means further includes; means for detecting the presence or absence of the other encoded information on the record; and means responsive to said detection means for rendering said removing means inactive at times when the record is absent of said other encoded information. - View Dependent Claims (28, 29, 30)
