Printing cartridge having IC device for interfacing with printing system
A printing cartridge for a printing system is provided. The printing cartridge comprises a housing configured so as to be insertable within a printing system and an integrated circuit device positioned on the housing so as to interface with the printing system when the printing cartridge is inserted therein. The housing holds a supply of media (and media colorant). The integrated circuit device has memory circuitry carrying data relating to the media (and media colorant) and communicates the data relating to the media (and media colorant) to the printing system when the integrated circuit device is interfaced therewith.
1. A printing cartridge for a printing system, the printing cartridge comprising:
a housing in which a supply of media is receivable, the housing being configured so as to be insertable within a printing system; and
an integrated circuit device positioned on the housing so as to interface with the printing system when the printing cartridge is inserted therein, the integrated circuit device having memory circuitry carrying data relating to the media and means for communicating the data relating to the media to the printing system when the integrated circuit device is interfaced therewith.
2. A printing cartridge as claimed in claim 1 , wherein the communication means of the integrated circuit device comprises a plurality of communication leads for electrically connecting the integrated circuit device to a processor of the printing system.
3. A printing cartridge as claimed in claim 1 , in which the integrated circuit device is in the form of a pre-programmed chip that is pre-programmed to store code carrying said data relating to the media.
4. A printing cartridge as claimed in claim 3 , in which the chip is pre-programmed to store code carrying encrypted data relating to the media.
5. A printing cartridge as claimed in claim 3 , in which the chip is pre-programmed to store code carrying data relating to at least one characteristic selected from the following group of characteristics: a serial number identifying the media, a type of the media and a length of the media.
6. A printing cartridge as claimed in claim 1 , wherein:
the housing is further configured to receive a media colorant supply arrangement;
the memory circuitry of the integrated ciruit device further carries data relating to the media colorant; and
the communication means of the integrated circuit device is arranged to communicate the data relating to the media colorant to the printing system when the integrated circuit device is interfaced therewith.
7. A printing cartridge as claimed in claim 6 , wherein the communication means of the integrated circuit device comprises a plurality of communication leads for electrically connecting the integrated circuit device to a processor of the printing system.
8. A printing cartridge as claimed in claim 6 , in which the integrated circuit device is in the form of a pre-programmed chip that is pre-programmed to store code carrying said data relating to the media colorant and the media.
9. A printing cartridge as claimed in claim 8 , in which the chip is pre-programmed to store code carrying encrypted data relating to the media.
10. A printing cartridge as claimed in claim 8 , in which the chip is pre-programmed to store code carrying data relating to at least one characteristic selected from the following group of characteristics: 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.
