BACKGROUND OF THE INVENTION
With the advent of the Internet has come the opportunity for the print media industry to publish “on-line” rather than producing and distributing traditional paper based publications. On-line publishing has a number of advantages. From the consumer's point of view, information is available on demand, information can be navigated via hypertext links, information can be searched, and information can be automatically personalized. From the publisher's point of view, the costs of printing and physical distribution are eliminated and the publication becomes more attractive to advertisers as it can be targeted to specific demographics and linked to product sites.
On-line publication also has disadvantages. Computer screens are inferior to paper. At the same quality as a magazine page, a SVGA computer screen displays only about a fifth as much information. Both CRT's (Cathode Ray Tubes) and LCD's (Liquid Crystal Displays) have brightness and contrast problems, particularly, when ambient light is strong. Ink on paper, being reflective rather than emissive is both bright and sharp in ambient light. Accordingly, people have a natural preference to read newspapers, magazines, catalogues, brochures and other publications in a bound paper based format.
Printers that incorporate a binding means may be connected to the Internet for the on-line publication of the bound documents or simply to allow users to produce their own documents in a bound format. However, the binding means will inherently consume some type of material to bind the pages together. This adds to the number of interruptions to printer operation because of the need to periodically replenish one more consumable material.
SUMMARY OF THE INVENTION
It is an object of the present invention to reduce the interruptions to a printers operation caused by the depletion of material consumed by the printer. Accordingly, the present invention provides a cartridge for a digital printer with integral binding means, the cartridge including:
a housing defining a plurality of storage areas wherein at least one of the storage areas contains colorant for printing and at least one of the other storage areas contains material for use by the binding means.
Preferably the material used by the binding means is a liquid adhesive. However, it will be appreciated that in other preferred forms, the material used by the binding means may be any suitable material such as string or staples.
In some preferred forms, the cartridge has a storage area for black ink.
In further preferred forms, the cartridge further includes storage areas for cyan, magenta, yellow and black ink. In still further preferred forms the cartridge further includes a storage area for infrared ink. It is desirable to also provide a storage area for fixative to reduce the drying time of the ink. Preferably, each storage area is sized corresponding to the expected levels of use of its contents relative to the intended print coverage for a number of printed pages.
In some embodiments the housing includes a thin walled casing adapted for engagement with a cover at its open end; and,
the storage areas are bladders wherein a separate bladder is provided for the adhesive and each different type of colorant used.
In a particularly preferred form the bladders have discharge nozzles and are adapted to be suspended from one end of the cup such that, in use, the colorant and adhesive are fed to the nozzles. Preferably the bladders are provided with means for suspending them from a pin extending through the cup adjacent the blind end. In a further preferred form the cover includes means to position the nozzles for engagement with corresponding ports in the printer.
In some preferred embodiments, the cartridge is formed from recyclable materials.
It will be appreciated that by providing a cartridge in accordance with the present invention, the binding material is replenished together with the colorant thereby reducing how frequently the printer operation is interrupted because of the depletion of a consumable material. The invention has many applications in on-line publication of newspapers, magazines, brochures and so on. The present invention will be described with particular reference to the Applicant's netpage system. An overview of this system is set out below. It has been developed to allow a large number of distributed users to interact with networked information via printed matter and optical sensors thereby to obtain interactive printed matter on demand from high-speed networked color printers.
For this purpose, the Applicant has developed a range of netpage printers. Of these, the wallprinter is designed to be wall mounted in the area where the user would normally first consume the morning news such as in the kitchen or beside the breakfast table. In light of this, it is expected that the wallprinter will be one of the most widely used of the netpage printers and therefore it will be described in detail below to illustrate one specific embodiment of the invention. However, it will be appreciated that this is merely one example of the invention, which may be embodied in many other forms.
