摘要:
A printhead with a series of overlapping printhead segments, all controlled by a print engine controller that adjusts for the temperature variable overlap between the segments to reduce visually perceptible artefacts. The controller sums a current dither value from a dither matrix with an overlap signal to provide an output value which is then compared in a comparator with an input continuous tone data value providing an output compensated dither value to control nozzles in the overlap region of the segments. Alternatively it uses a software program to provide the compensated dither matrix. A temperature sensor measures the degree of overlap of the segments to generate the overlap signal. The degree of overlap may be determined for various temperatures and stored in a ROM.

Provided is a page expansion and printing method for a pagewidth inkjet printer. The method features the step of receiving a page description having a bi-level black layer and a contone CMYK (Cyan Magenta Yellow black) layer from a host and storing said page description in a memory. The method also includes the steps of decompressing the respective layers in parallel, halftoning the contone CMYK layer to bi-level CMYK, compositing the bi-level black layer over the bi-level CMYK layer, and transmitting the image to a memory buffer for printing by the pagewidth printer.
摘要:
An inkjet printer includes a body housing a print engine configured to transport print media. The print engine includes a replaceable ink cartridge for storing ink, and a printhead assembly configured to eject the ink upon the print media. A retractable cover is pivotally mounted relative to the body and is able to be pivoted to form a guide which can guide print media to the print engine for printing. A capping mechanism is configured to cap the printhead assembly.

A method of integrating audio and an encoded writing medium using an interactive apparatus is disclosed. The method comprises activating an audio recording mode of the interactive apparatus. The interactive apparatus comprises a writing tool, an audio input device, and an audio output device. Furthermore, while recording audio, the method comprises synchronously writing on the encoded writing medium with the writing tool to create a playback-enabling graphical element corresponding to the recorded audio.

A method of enabling recorded audio to be associated with a location on a surface is provided. The surface has coded data printed thereon, which is indicative of a plurality of locations on the surface. The method comprises the steps of: interacting with the surface using an optical sensing device comprising a microphone; recording audio using the microphone; reading some of the coded data during the interaction; determining a position of the sensing device using the read coded data; and communicating, to a computer system, position data indicative of the position of the sensing device and audio data corresponding to the recorded audio, thereby enabling the computer system to associate the audio data with the position.
摘要:
An effects module is provided for a modular printer. The effects module includes a body, in turn, housing electronics. A CHOOSE actuator is mounted to the body in electrical connection with the electronics and enables a user to choose between a number of different types of effects to be applied to a stored image. A SELECT actuator is mounted to the body in electrical connection with the electronics and enables the user to select one of the effects. An APPLY actuator is mounted to the body in electrical connection with the electronics and enables the user to apply the effect to the stored image.
摘要:
A printer is provided for authenticating a replaceable ink cartridge. The printer includes a processor. The replaceable ink cartridge can be releasably coupled to the processor and includes a first integrated circuit (IC). A printhead is interfaced to the processor and is configured to print ink supplied from the ink cartridge. A second IC is interfaced to the processor and, together with the processor, can be used to authenticate the first IC and therefore the ink cartridge.
摘要:
A method of linking an object to a print medium, comprising the step of: submitting a request to associate the object with a print media identifier of the print medium, submission of the request facilitating identification of the object and the print media identifier; wherein, the association of the object and the print media identifier is recorded in a database, the object being retrievable from the database using the print media identifier.
摘要:
A method of generating an association between an object and a sticker on a surface, the sticker having disposed therein or thereon coded data at least partially indicative of a sticker identity, the method including, in a computer system: receiving indicating data from a sensing device, the indicating data being at least partially indicative of the identity of the sticker, the sensing device being responsive to sensing at least some of the coded data to generate the indicating data; identifying, using the indicating data, the identity of the sticker on the surface; and, generating an association based at least partially on the sticker identity and an object.
摘要:
A system for printing an almanac on a print medium, the system comprising: a mobile telecommunications device which comprises: a printer module to print the almanac on the print medium; and, a sensor module to sense a print media identifier of the print medium.
