Abstract

A printing system is disclosed. The printing system includes a first printer to print a first type of data to a medium and to print a first barcode on the medium including variable to be printed on the medium and a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium.

Claims

1. A printing system comprising:

a first printer to print a first type of data to a medium and to print a first barcode on the medium including variable to be printed on the medium; and

a second printer to print the variable data to the medium based on the first barcode and to print a second barcode to the medium for verification that the variable data has been accurately printed to the medium.

2. The printing system of claim 1 wherein the first printer encrypts the variable data prior to printing the first barcode.

3. The printing system of claim 1 wherein the second printer decrypts the variable data from the first barcode prior to prior to printing the variable data to the medium.

4. The printing system of claim 3 wherein the second printer encrypts the data from the first barcode prior to printing the second barcode.

5. The printing system of claim 3 wherein the second barcode is printed in a known position on the medium relative to the first barcode.

6. The printing system of claim 3 wherein the second barcode is identical to the first barcode.

7. The printing system of claim 6 further comprising a scanner to verify that the second barcode is identical to the first barcode.

8. The printing system of claim 1 wherein the first type of data comprises at least one of text data and image data.

9. A method comprising:

reading a first barcode printed on a medium including variable data;

printing the variable data to the medium based on the first barcode;

generating a second barcode from the variable data included in the first barcode; and

printing the second barcode to the print medium.

10. The method of claim 9 further comprising decrypting the variable data from the first barcode prior to printing the variable data to the medium.

11. The method of claim 9 further comprising encrypting the variable data from the first barcode prior to generating the second barcode.

12. The method of claim 9 wherein the second barcode is printed in a known position on the medium relative to the first barcode.

13. The method of claim 9 wherein the second barcode is identical to the first barcode.

14. The method of claim 13 further comprising verifying that the second barcode is identical to the first barcode.

15. A printer comprising a control unit to read a first barcode printed on a medium including variable data, print the variable data to the medium based on the first barcode, generate a second barcode from the variable data included in the first barcode and print the second barcode to the print medium.

16. The printer of claim 15 wherein the control unit further decrypts the variable data from the first barcode prior to printing the variable data to the medium.

17. The printer of claim 15 wherein the control unit further encrypts the variable data from the first barcode prior to generating the second barcode.

18. The printer of claim 15 wherein the second barcode is printed in a known position on the medium relative to the first barcode.

19. The printer of claim 15 wherein the second barcode is identical to the first barcode.

20. The printer of claim 19 further comprising verifying that the second barcode is identical to the first barcode.

21. An article of manufacture comprising a machine-readable medium including data that, when accessed by a machine, cause the machine to perform operations comprising:

reading a first barcode printed on a medium including variable data;

printing the variable data to the medium based on the first barcode;

generating a second barcode from the variable data included in the first barcode; and

printing the second barcode to the print medium.

22. The article of manufacture of claim 21 wherein the machine-accessible medium includes data that causes the machine to perform further operations comprising decrypting the variable data from the first barcode prior to printing the variable data to the medium.

23. The article of manufacture of claim 21 wherein the machine-accessible medium includes data that causes the machine to perform further operations comprising encrypting the variable data from the first barcode prior to generating the second barcode.

24. The article of manufacture of claim 21 wherein the second barcode is printed in a known position on the medium relative to the first barcode.

25. The article of manufacture of claim 21 wherein the second barcode is identical to the first barcode.

26. The article of manufacture of claim 25 further comprising verifying that the second barcode is identical to the first barcode.
