A printhead is provided having at least one row that comprises a plurality of sets of n adjacent printing nozzles. Each nozzle is configured to expel ink in response to a fire signal, such that, for each set of nozzles, a fire signal is provided in accordance with the sequence: [nozzle position 1, nozzle position n, nozzle position 2, nozzle position (n−1), . . . , nozzle position x].

A processor is provided for a printer. The processor includes an address, data and control bus. An expander unit is coupled to the bus and is configured to decompress a bi-level black layer of a page to be printed. A decoder unit is coupled to the bus and is configured to decompress a contone layer of the page to be printed. A halftoner/compositor unit is coupled to the bus. The halftoner/compositor unit is configured to halftone the decompressed contone layer to form a bi-level cyan, yellow, magenta, and black (CYMK) layer and then composite the decompressed bi-level black layer over the bi-level CYMK layer to form a bi-level CYMK image of the page to be printed.

A method for handling information in an information management system is provided. The system includes a digital pen capable of reading a position code and communicating at least part thereof in a communication network. Each digital pen is associated with a respective pen identifier. The method includes associating an alias with a pen identifier in dependence on an interactive element which is coded by part of the position code printed on a surface. The alias is indicative of a role or behavior of a pen user when the user communicates via a digital pen with the information management system.
摘要:
A printhead is provided having elongate printhead modules arranged to aggregately extend across a pagewidth and controllers for processing print data into dot data and for controlling the printhead modules in accordance with the dot data. Each printhead module has plural rows of ink ejection nozzles. The nozzle rows of at least one of the printhead modules are longer than the nozzle rows of the other printhead modules. The controllers control ink ejection of the nozzles of the printhead modules in accordance with the dot data. At least one of the controllers is arranged to control all of the printhead modules and at least one other of the controllers is arranged to control only one of the printhead modules.

A printer includes a processor. A replaceable ink cartridge includes a first integrated circuit (IC) containing print quality information and which is configured to be interfaced, in a releasable manner, to the processor. A replaceable printhead module includes a printhead which is configured to be interfaced, in a releasable manner, to the processor. The printhead is configured to print ink supplied from the ink cartridge using the print quality information.
摘要:
A method of interacting with a product item is provided. The product item comprises a product contained in a package, the package having an interface surface containing information relating to the product, the interface surface having disposed thereon coded data identifying a product identity and a plurality of locations on the interface surface. The method comprises the step of: (a) sensing at least some of the coded data in the vicinity of the sensing device when a user interacts with the product item by placing a sensing device in an operative position relative to the interface surface; (b) generating indicating data using at least some of the sensed coded data, said indicating data comprising data regarding the identity of the product item and a position of the sensing device relative to the interface surface; and (c) sending the indicating data to a computer system. The method enables the computer system to identify the interaction between the user and the product item.
摘要:
A printer controller for supplying dot data to an inkjet printhead is provided. The printhead comprises a plurality of transversely aligned color channels. Each color channel comprises at least one nozzle row extending longitudinally along the printhead with each nozzle in a color channel ejecting the same colored ink. The printhead is comprised of a plurality of printhead modules with each printhead module comprising a respective segment of each nozzle row. The printer controller is programmed to supply dot data such that each of the printhead modules fires a respective segment within a predetermined segment-time, wherein at least one of the fired segments is contained in a different color channel from at least one other of the fired segments.
摘要:
A printhead is provided having at least first and second rows of print nozzles. Each nozzle has first circuitry of a first type arranged on an opposite side of the nozzle as second circuitry of a second type. The respective positions of the first and second circuitry of each nozzle of the first row are rotated 180 degrees relative to the respective positions of the first and second circuitry of each nozzle of the second row.
摘要:
A method of generating an association between an object, a location on a surface and a sticker on the surface, the sticker having disposed therein or thereon first coded data at least partially indicative of a sticker identity and at least one action, the surface having disposed therein or thereon second coded data indicative of a plurality of locations on the surface respectively, the method including, in a computer system: receiving indicating data from a sensing device, the indicating data being at least partially indicative of the at least one action and at least one position of the sensing device relative to the surface, the sensing device, when placed in an operative position relative to at least some of the sticker and at least some of the surface, being responsive to sense at least some of the first coded data and at least some of the second coded data and generate the indicating data using the sensed first coded data and sensed second coded data; identifying, using the indicating data, the sticker identity, the at least one action, the at least one position and the object; generating, using the at least one action, an association based at least partially on the sticker identity, the at least one position and the object.
