2. A printing cartridge as claimed in claim 1 , wherein the two dimensional code carries data related to at least one of: a serial number identifying the media, a type of the media and a length of the media.

3. A printing cartridge as claimed in claim 1 , in which the two dimensional code is protected with an encryption algorithm.

4. A printing cartridge as claimed in claim 1 , in which the two dimensional code incorporates error-correcting code.

5. A printing cartridge as claimed in claim 4 , in which the error-correcting code is in the form of Reed-Solomon code.

6. A printing cartridge that comprises

a housing;

media and media colorant supply arrangements positioned within the housing and containing a roll of media and a supply of media colorant, respectively; and

a two dimensional code positioned on the housing, the two dimensional code carrying data relating to the roll of media and the media colorant and instructions relating to a manner of operation of a printing device to which the printing cartridge is mountable in accordance with the data.

7. A printing cartridge as claimed in claim 6 , wherein the two dimensional code carries data related to at least one of: a serial number identifying the media, a serial number identifying the media colorant, a length of the media, a type of the media, a viscosity of the media colorant, a surface tension of the media colorant, optical characteristics of the media colorant and an optimal ink drop volume of the media colorant corresponding to the type of media.

8. A printing cartridge as claimed in claim 6 , in which the two dimensional code is protected with an encryption algorithm.

9. A printing cartridge as claimed in claim 6 , in which the two dimensional code incorporates error-correcting code.
