Abstract

In a method of authorizing a supply for use with a printing system, a supply is provided having a memory containing a first and second codes and supply-specific data, which uniquely identifies the supply. The first code, the second code and the supply-specific data are retrieved from the memory of the supply. The first and second codes are translated using the supply-specific data. The translated first code is compared to a third code and the translated second code is compared to a fourth code. Use of the supply with the printing system is authorized when the translated first code corresponds to the third code and the translated second code corresponds to the fourth code. Use of the supply with the printing system is prevented when either the translated first code does not correspond to the third code, or the translated second code does not correspond to the fourth code.

Claims

1. A method of authorizing a supply for use with a printing system comprising:

providing a supply having a memory containing first and second codes and supply-specific data, which uniquely identifies the supply;

retrieving the first code, the second code and the supply-specific data from the memory of the supply;

translating the first code using the supply-specific data;

translating the second code using the supply-specific data;

comparing the translated first code to a third code;

comparing the translated second code to a fourth code;

authorizing use of the supply with the printing system when the translated first code corresponds to the third code and the translated second code corresponds to the fourth code; and

preventing use of the supply with the printing system when either the translated first code does not correspond to the third code, or the translated second code does not correspond to the fourth code.

2. The method of claim 1, wherein:

translating the first code comprises decoding or decrypting the first code using the supply-specific data; and

translating the second code comprises decoding or decrypting the second code using the supply-specific data.

3. The method of claim 1, wherein:

the method further comprises retrieving a first private key from a memory; and

translating the first code comprises decoding or decrypting the first code using the supply-specific data and the first private key.

4. The method of claim 3, wherein:

the method further comprises retrieving a second private key; and

translating the second code comprises decoding or decrypting the second code using the supply-specific data and the second private key.

5. The method of claim 4, wherein the first private key and the second private key are retrieved from a memory of the printing system.

6. The method of claim 1, wherein:

the supply is selected from the group consisting of a card supply, and ink cartridge, a thermal print ribbon and an overlaminate supply; and

providing the supply comprises installing the supply in a printing device of the printing system.

7. A printing system comprising:

a printing device;

a supply installed in the printing device, the supply including a memory containing a first code, a second code and supply-specific data; and

an application stored in a tangible computer-readable medium comprising instructions executable by a microprocessor for;

retrieving the first code, the second code and the supply-specific data from the memory of the supply;

translating the first code using the supply-specific data;

translating the second code using the supply-specific data;

comparing the translated first code to a third code;

comparing the translated second code to a fourth code;

authorizing use of the supply with the printing device when the translated first code corresponds to the third code and the translated second code corresponds to the fourth code; and

preventing use of the supply with the printing device when either the translated first code does not correspond to the third code, or the translated second code does not correspond to the fourth code.

8. The system of claim 7, wherein:

the instructions for translating the first code comprise instructions for decoding or decrypting the first code using the supply-specific data; and

the instructions for translating the second code comprise instructions for decoding or decrypting the second code using the supply-specific data.

9. The system of claim 7, wherein:

the instructions further comprise instructions for retrieving a first private key from a memory; and

the instructions for translating the first code comprise instructions for decoding or decrypting the first code using the supply-specific data and the first private key.

10. The system of claim 9, wherein:

the instructions further comprise instructions for retrieving a second private key; and

the instructions for translating the second code comprise instructions for decoding or decrypting the second code using the supply-specific data and the second private key.

11. The method of claim 10, wherein:

the printing device comprises a memory containing the first and second private keys; and

the instructions comprise instructions for retrieving the first and second private keys from the memory of the printing device.

12. The system of claim 7, wherein the supply is selected from the group consisting of a card supply, and ink cartridge, a thermal print ribbon and an overlaminate supply.
