Abstract

A printing device includes: a processor; a printing cartridge having a housing and a supply of media; a memory storing at least one of: (a) a plurality of values representing various characteristics of the printing cartridge, and (b) a script containing instructions relating to an operation of a printhead of the print device; a data lookup table storing a plurality of first codes, each of the first codes corresponding either one of the plurality of values stored in the memory, or the script; a radio frequency tag embedded within the housing of the printing cartridge and carrying one or more second codes; and a radio frequency tag reader communicating the one nor more second codes to the processor. The processor applies an algorithm to the one or more second codes to identify a first code associated therewith, and further determines a value or a script stored in the memory corresponding to the identified first code.

Claims

1. A printing device comprising:

a processor;

a printing cartridge having a housing and a supply of media;

a memory storing at least on of;

(a) a plurality of values representing various characteristics of the printing cartridge, and (b) a script containing instructions relating to an operation of a printhead of the print device;

a data lookup table storing a plurality of first codes, each of the first codes corresponding either one of the plurality of values stored in the memory, or the script;

a radio frequency tag embedded within the housing of the printing cartridge and carrying one or more second codes; and

a radio frequency tag reader communicating the one or more second codes to the processor, wherein

the processor applies an algorithm to the one or more second codes to identify a first code associated therewith, and further determines a value or a script stored in the memory corresponding to the identified first code.

2. A printing device as claimed in claim 1, wherein the radio frequency tag is a passive radio frequency tag.

3. A printing device as claimed in claim 1, wherein the radio frequency tag reader includes an antenna-capacitor circuit for emitting a radio wave field for powering the radio frequency tag.

4. A printing device as claimed in claim 1, wherein the printing cartridge further comprises a supply of media colorant within the housing.

5. A print device as claimed in claim 1, wherein the plurality of values stored in the memory include:

a serial number identifying the media colorant, 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.
