ABSTRACT:
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not applicable.
FIELD OF THE INVENTION
The present invention relates to the field of printer technology and discloses a printing cartridge for use in an image printer or the like. In particular, the present invention discloses a printing cartridge which incorporates radio frequency identification.
BACKGROUND OF THE INVENTION
Recently, digital printing technology has been proposed as a suitable replacement for traditional camera and photographic film techniques. The traditional film and photographic techniques rely upon a film roll having a number of pre-formatted negatives which are drawn past a lensing system and onto which is imaged a negative of a image taken by the lensing system. Upon the completion of a film roll, the film is rewound into its container and forwarded to a processing shop for processing and development of the negatives so as to produce a corresponding positive set of photos.
Unfortunately, such a system has a number of significant drawbacks. Firstly, the chemicals utilized are obviously very sensitive to light and any light impinging upon the film roll will lead to exposure of the film. They are therefore required to operate in a light sensitive environment where the light imaging is totally controlled. This results in onerous engineering requirements leading to increased expense. Further, film processing techniques require the utilizing of a “negative” and its subsequent processing onto a “positive” film paper through the utilization of processing chemicals and complex silver halide processing etc. This is generally unduly cumbersome, complex and expensive. Further, such a system through its popularity has lead to the standardization on certain size film formats and generally minimal flexibility is possible with the aforementioned techniques.
Recently, all digital cameras have been introduced. These camera devices normally utilize a charge coupled device (CCD) or other form of photosensor connected to a processing chip which in turn is connected to and controls a media storage device which can take the form of a detachable magnetic card. In this type of device, the image is captured by the CCD and stored on the magnetic storage device. At some later time, the image or images which have been captured are down loaded to a computer device and printed out for viewing. The digital camera has the disadvantage that access to images is non-immediate and the further post processing step of loading onto a computer system is required, the further post processing often being a hindrance to ready and expedient use.
Therefore, there remains a general need for an improved form of camera picture image production apparatus which is convenient, simple and effective in operation. Further, there also remains a need for a simple form of portable, immediate print media on which images can be effectively reproduced.
In the parent application, there is disclosed the use of an authentication chip to provide information in connection with the print media and the media colorant that is supplied with the cartridge.
The Applicant has identified that it would be highly desirable to provide a means whereby information concerning one or both of the media and the media colorant could be supplied together with the cartridge. The reason for this is that such information could be used, in a suitable form, by a processor of such a device to enhance operation of a printing mechanism. It will be appreciated that printing mechanisms need to operate differently with different types of media and media colorant. It follows that it would be useful to supply information concerning media and media colorant to a controller of the printing mechanism so that operation of the printing mechanism could be automatically adjusted to suit the particular media and media colorant.
With suitable encryption techniques, this could be used to inhibit after-market refilling. As is well known in the field of printing technology, such after-market refilling has become a cause for substantial concern in the printing industry.
