A computer printer is a piece of hardware for a computer. It allows a user to print items on paper, such as letters and pictures. Mostly a printer prints under the control of a computer.

Color printer characterization using optimization theory and neural networks

A color management method/apparatus generates image color matching and International Color Consortium (ICC) color printer profiles using a reduced number of color patch measurements. Color printer characterization, and the generation of ICC profiles usually require a large number of measured data points or color patches and complex interpolation techniques. This invention provides an optimization method/apparatus for performing LAB to CMYK color space conversion, gamut mapping, and gray component replacement. A gamut trained network architecture performs LAB to CMYK color space conversion to generate a color profile lookup table for a color printer, or alternatively, to directly control the color printer in accordance with the a plurality of color patches that accurately. represent the gamut of the color printer. More specifically, a feed forward neural network is trained using an ANSI/IT-8 basic data set consisting of 182 data points or color patches, or using a lesser number of data points such as 150 or 101 data points when redundant data points within linear regions of the 182 data point set are removed. A 5-to-7 neuron neural network architecture is preferred to perform the LAB to CMYK color space conversion as the profile lookup table is built, or as the printer is directly controlled. For each CMYK signal, an ink optimization criteria is applied, to thereby control ink parameters such as the total quantity of ink in each CMYK ink printed pixel, and/or to control the total quantity of black ink in each CMYK ink printed pixel.

Printer and ink cartridge attached thereto

In a printer of the present invention, an EEPROM that carries out sequential access and has a relatively small storage capacity is applied for storage elements mounted on both black and color ink cartridges, which are detachably attached to the printer. Pieces of information relating to each ink cartridge, for example, pieces of information on remaining quantities of respective inks in the ink cartridge, are stored in the storage element of the ink cartridge. A format of addressing adopted in the storage elements of the ink cartridges Is different from that adopted in an EEPROM incorporated in a printer main body of the printer. A control IC provided in the printer accordingly converts the storage format of addressing, before writing the information into the storage elements of the ink cartridges. In the printer, a RAM is mounted with the control IC on a carriage, and the pieces of information to be written Into the storage elements of the ink cartridges are temporarily registered in the RAM. The pieces of information are then written into the respective storage elements of the black and color ink cartridges, for example, at a timing of a powe-off operation. The signal lines and the memory used in the course of writing the information into the storage elements are identical with the signal lines, through which print data are transmitted to a print head mounted on the carriage of the printer, and the memory, in which the print data are stored. The arrangement of the present invention reduces the manufacturing cost of the ink cartridge and also enables size reduction of the whole printer.< / PTEXT>

System and method for dispensing digital information from an automated transaction machine

An automated teller machine (ATM) (10) includes an input device (16) a card reader (20), a cash dispenser (24), and an output device (18). The ATM is operative to read account information from a card with the card reader and validate a user PIN input through the input device. The ATM may also be operative to dispense cash with the cash dispenser and dispense digital content with the output device responsive to user input selections. The ATM may be further operative to charge a user fee to an account associated with the card for the dispense of cash and digital content. Digital content dispensed by the ATM may include sound recordings such as MP3 files, video files, books, graphics, photographs, and other digital data. In cases where the ATM dispenses visual content the output device may include a printer that is operative to output printed photographs. Photographic image files may be acquired by the ATM from a remote photo processor or other digital information source accessible through the Internet or other network. The ATM may be operated through user inputs to manipulate image files. Image files may also be selectively received from or dispensed to a portable storage medium through a reading device or recording device connected to the ATM. Fees associated with the dispense of the image files may be transferred from an account associated with a user.

Ink cartridge and printer using the same

In an ink jet printer of the present invention, in order to reduce the manufacturing cost, an inexpensive EEPROM enabling only sequential accesses is applied for storage elements incorporated in a black ink cartridge and a color ink cartridge. The data array of a memory cell included in each of the storage elements mounted on the ink cartridges is determined in such a manner that a second storage area, in which rewritable data, for example, data on remaining quantities of inks in the ink cartridge, are stored, is accessed prior to a first storage area, in which read only data are stored. This configuration enables the rewritable data to be securely written into the second storage area even after a power-off operation. The second storage area has two memory divisions allocated to each ink, that is, a first ink remaining quantity memory division and a second ink remaining quantity memory division. Latest data on the remaining quantity of each ink is alternately written into these two memory divisions. Alternatively, the latest data on the remaining quantity of each ink is written into these two memory divisions in a duplicated manner. Each ink remaining quantity memory division has a write complete flag to determine whether or not a writing operation has been completed normally in the ink remaining quantity memory division. This arrangement enables the remaining quantities of the respective inks to be monitored accurately and continuously.

Printer control and document management system

A printer control and information management system is provided employing numerous individual satellite modules, and providing an enterprise-wide output system capable of receiving all types of input and redirecting of all types of output. Data can be inputted from any location in an enterprise system and coordinated into a coherent format for reporting and forms processing. Forms can be automatically generated based on the data inputted, which forms can be directed to the appropriate personnel. The system provides for notifications to the appropriate personnel in order to resolve problems which may arise from the operation of the various equipment utilized in the enterprise network system. Information can be redirected to anyone within the system, the user identifying the manner and format of the information to be presented. Thus, inbound reports can be received from different systems and outputs delivered in the format that is preferred by the user. Report recognition is provided for any application, with the ability to merge textual information with electronic forms. Additionally, the forms can be completed with bar code information to prevent inadvertent disclosure of sensitive information. Large and contiguous host generated reports can be electronically distributed to users, as well as the ability to automatically fax any type of report directly to any recipient. The system can be accessed via the Internet for ease of inputting and reviewing information at any location.
