A compact desktop computer system is provided that has a small footprint due to integration of a pagewidth printer into the computer system's keyboard. A data bus interconnects the keyboard and conveys commands from the keyboard to a computer, and signals from the computer to the integrated printer. The keyboard is fitted with a port to receive an ink cartridge that is in fluid communication with the pagewidth printer. The printer includes a transport assembly to move print media from an entry slot to an ejection slot located on opposing sides of the keyboard's housing

A system for generating printed mail pieces, starting from a print file, having: a printer for printing; a processing device for processing printed items into mail pieces; a control unit for controlling the printer and the processing device, and memory. The memory contains processing code for controlling the control unit for processing the rough pint file into a processed print file, and representation code for causing the processing instructions of the processing code to be represented in humanly perceptible form. The representation code is editable for changing at least the representations of the processing instructions and convertible into the processing code. Alternatively, the memory can contain a set of processing subroutines with which processing subroutines representation codes can be composed which differ from each other at least as regards processing instructions included therein, and which are each convertible into corresponding processing code. Also described is computer software for such a system.

A printing cartridge includes a housing in which a supply of media is receivable. An integrated circuit device is positioned on the housing. The integrated circuit device has memory circuitry carrying data relating to the media.
摘要:
The present invention relates to a cartridge for use with a digital printing device. The cartridge includes a first casing portion for housing print media and a second casing portion for housing a supply of ink. The ink supply is formed by having the second casing portion segregated into distinct chambers for storing a supply of different colored inks, with each ink storage chamber having a corresponding ink outlet closed with a pierceable seal and is defined at least in part by a collapsible membrane.

A data structure encoded on a surface of an object, and a method of generating such a data structure. The data structure includes a plurality of block data regions. Each of the block regions includes an encoded data region containing data in encoded form, a clock mark structure located adjacent a first peripheral portion of the encoded data region, and a target structure located adjacent the clock mark structure. Each of the block data regions further includes an orientation data structure indicative of an orientation of the data structure.

A viewer (100) is provided for displaying and allowing interaction with interactive information and application interfaces. The viewer includes at least one code sensor (112) for sensing coded data (202) disposed on a surface (200). The viewer transmits data derived from the sensed data to a computer system and receives, in response, data for display on a color display (102). The visual content of the display may be synchronized with the visual content of the underlying coded surface. The viewer also includes a printer mechanism (200) for transferring to the underlying surface input captured via a touch-sensitive overlay (132) on the display (102).
摘要:
An ink jet printhead chip that is the product of an integrated circuit fabrication technique includes a wafer substrate having a front surface and a rear surface. A plurality of ink passages are defined through the wafer substrate, so that each ink passage defines an inlet at a rear surface of the wafer substrate and an outlet at a front surface of the wafer substrate. Each ink passage is in fluid communication with an ink supply at the rear surface of the wafer substrate. A plurality of actuators are positioned on the rear surface of the wafer substrate and are operatively arranged with respect to the ink passages to generate an ink flow through each passage, from the rear surface to the front surface, when activated.
摘要:
An ink distribution assembly for a page width ink jet printhead integrated circuit having sets of ink inlet openings for receiving particular colour ink is provided. The assembly includes a carrier having opposed ink supply and printhead sides which defines feed openings in fluid communication with the inlet openings of the integrated circuit. The supply side defines discrete feed formations in fluid communication with the inlet openings for receiving particular colour ink. The printhead side defines supply channels in fluid communication with the feed formations via passages defined by the carrier. A cover is engaged at the supply side and is shaped with the supply side so as to define a roof for, and pathways in fluid communication with, the feed formations. The carrier defines supply openings in fluid communication with the pathways and includes cover plates engaged at the printhead side to define roofs for the supply channels.

A printer arrangement comprises a printing unit (1) receivable in a conveyance (132). A wireless data communications port is incorporated in the unit for enabling data to be printed to be transmitted to the printing unit in a wireless manner.
摘要:
An inkjet printhead chip includes a wafer substrate that defines a plurality of ink inlet channels. A drive circuitry layer is positioned on the wafer substrate. A plurality of nozzle assemblies is positioned on the wafer substrate. Each nozzle assembly includes a nozzle chamber structure that comprises a fixed portion that bounds a respective ink inlet channel and a movable portion. The fixed and movable portions define a nozzle chamber in fluid communication with the ink inlet channel. The movable portion defines an ink ejection port and is movable relative to the fixed portion so that ink is ejected from the ink ejection port. Peripheries of the fixed and movable portions are shaped and relatively positioned so that ink in the nozzle chamber establishes a meniscus between the peripheries that defines a fluidic seal to inhibit the egress of ink during operation. An actuator is connected to the drive circuitry layer to receive an electrical signal from the drive circuitry layer and is arranged to act on the movable portion to displace the movable portion with respect to the fixed portion on receipt of the electrical signal.
