摘要:
A print medium for use with a mobile device having a printer, the print medium comprising: a substrate defining first and second opposite faces; and an orientation indicator disposed on at least one of the first and second faces, the orientation indicator being indicative of at least one orientation of the print medium, thereby enabling the mobile device to determine the print medium's orientation prior to printing thereon.

A data card reader for an electronic apparatus is arranged to read an optical pattern printed upon a data card. The reader includes a card transport assembly to move the data card along a path and a reading assembly that traverses the path to read the pattern. The reading assembly is comprised of an elongate body of transparent material formed with an elongate lens and a parallel series of discrete lenses. A series of LEDs is mounted within the body below the elongate lens and similarly a series of CCD optical sensors is mounted beneath the series of discrete lenses. In use, light from the LEDs is focused on the data card by the elongate lens and reflected back onto the discrete lenses. The discrete lenses in turn focus the reflected light onto the CCD optical sensors. Output from the sensors is coupled to a processor which operates to decode the pattern. By forming both the elongate lens and the discrete lenses out of a single piece of transparent material a simple and easily constructed reader is provided.

A print media and ink supply cartridge includes an outer housing in which there is located a roll of print media located about a cylindrical former. The former includes a number of internal longitudinal ink storage volumes that are filled with hydrophobic sponges. One end of the former has winding airways formed into it that communicate with the internal ink storage volumes. An opposing end of the former includes a number of ink outlet ports that communicate with corresponding outlets in the housing. The cartridge includes a pair of print media transport rollers arranged to be driven by a power source external to the cartridge.
摘要:
A system for printing a photograph on a print medium, the system comprising: a mobile telecommunications device which comprises: a camera to capture the photograph; a printer module to print the photograph on the print medium; and, a sensor module to sense a print media identifier of the print medium.
摘要:
A method of retrieving video data using a print medium, comprising the steps of: determining a print media identifier from the print medium using a sensor module of a mobile telecommunications device, the print media identifier having been linked to the video data; and, retrieving, using the mobile telecommunications device, the video data.
摘要:
A method of generating halftone print data for overlapping end portions of a pair of consecutive printhead chips in an array of two or more printhead chips where an end portion of a first printhead chip overlaps an end portion of a second printhead chip, each printhead chip including a plurality of ink ejection nozzles, includes generating continuous tone print data for the array of printhead chips, The continuous tone print data for said overlapping end portions is interpolated according to an algorithm such that ink ejection nozzle utilization decreases in each said overlapping end portion towards respective ends of the printhead chips.
摘要:
A method of generating print data includes the step of receiving compressed page data having a layer of continuous tone data and a layer of bi-level data. The continuous tone data and the bi-level data are decompressed. The continuous tone data is halftoned and the bi-level data is composited over the continuous tone data.
摘要:
An arrangement for reading data recorded in infra-red on the surface of a card upon which may also be recorded a visual representation is disclosed. The reading apparatus comprises scanning means for scanning in the encoded fault tolerant digital form of the data on the surface, means for processing the scanned data and for decoding the data into a secondary digital format and means for outputting the secondary digital format to an output device with which the secondary digital format is usable. The output device presents the data in a human readable form. The data may include text and/or images equivalent to recording a book, newspaper, manual or a database.
摘要:
Where the bandwidth of a data link between a printer and a computer is limited it may be desirable to transmit compressed page layout data over the data link. A printer controller chip is provided that processes compressed page layout data corresponding to a page layout having a bi-level black layer and a continuous tone graphics layer. The printer controller includes a number of functional modules including an edge delta runlength (EDRL) expander to derive bi-level black layer data from the compressed data. The controller also incorporates a JPEG decoder to derive continuous tone layer data from the compressed data. A halftoner and compositer module is provided to halftone the continuous tone data to bi-level CMYK data and to composite the bi-level layout data over the bi-level CMYK data to produce page layout print data. A printhead interface processes the page layout print data to generate signals to drive a pagewidth printhead.
摘要:
A method of using a mobile device to authenticate a printed token and output an image associated with the token, the mobile device comprising a sensor and processing means, the method comprising the steps of: using the sensor to sense coded data on the printed token; using the processing means to determine, from the sensed coded data, at least an identity of the token; authenticating the token using the identity; based on at least the identity, determining an image associated with the token; and outputting the image from the mobile device in a visible form.
