  • Patent number: 6680783
    Abstract: A method for printing an indicium with a printer coupled to a personal computer includes the steps of collecting indicium data in memory of the PC, generating an indicium bar code relating to the indicium data, creating in the PC memory a printable image of a valid indicium including the indicium bar code, printing the printable image, and destroying the printable image in the PC memory as soon as the printable image has been printed. Messages of the PC operating system can be monitored for printing activity such that the printable image can be modified after a first copy of the printable image has been printed. The step of creating a printable image includes determining if more than one copy of the indicium is to be printed, and changing the number of copies to be printed to one when more than one copy is determined. The step of creating a printable image renders an indicium image to a memory device context. The printable image can be destroyed by overwriting the printable image with other information.

  • Patent number: 6646763
    Abstract: Methods, systems, and apparatus for mapping a nonspectral representation of a target color, such as an input color tuple, to a set of concentration values for a set of device-specific colorants. The invention includes using the input color tuple to derive a first set of colorant concentration values from a color lookup table; and refining the first set of colorant concentration values by an iterative non-linear process to generate a final set of colorant concentration values. The first set of colorant concentration values can derived by using an input color tuple as an index to obtain grid-point concentration values at two grid points of the color lookup table and calculating the first set of colorant concentration values as a linear interpolation of the grid-point concentration values.

  • Patent number: 6643028
    Abstract: In this invention, a digital copying machine to be connected to a network feeds originals in each document unit for each sheet by use of an ADF to read the images of the originals and prints the read images in each document unit for each page in a printing form selected by the user. Therefore, a plurality of original images read in each document unit can be effectively confirmed in accordance with the purpose of the user on the spot where the reading operation is effected. Further, the actual concentration can be adjusted while observing reduced images on the confirmation sheet and inputting of an actual image and inputting for correction can be easily attained. In a case where a specified page among a plurality of originals is scanned again, all of the originals are set on the original table of the ADF without extracting the specified page from the originals and the specified page can be scanned again.

  • Patent number: 6636327
    Abstract: An image processing apparatus is controlled in accordance with the status of an interface and the contents of data. Specifically, so long as the number J of jobs, which are executed by the copier system at the same time, and the number N of channels, which are required by a target job during one cycle, are obtained, dynamic paper feeding timing Wd can be acquired from ideal paper feeding timing Ws, while taking delay time X into account. The preceding paper feeding is performed using paper feeding timing Wd. Further, based on predicted data, a check is performed to determine whether image transmission will be successful without a buffer memory being used. When it is determined that the buffer memory is not required for the image transmission, image data are received without the buffer memory being obtained. When it is determined that the buffer memory is required for the image transmission, an adequate buffer memory is acquired for the reception of image data.

  • Patent number: 6633393
    Abstract: A printer is provided which reliably detects front and back sides of a print medium and the print data to be printed to the respective sides, and automatically prints print data to the correct side of the print medium. A print command interpreter 203 interprets a print command received from the host device to determines the print medium side indicated by the print command for printing associated print data. An inserted side detecting means 207 detects which side of the print medium inserted to the printer is facing a particular direction. Control units 204 and 208 print the print data when the print medium side detected by the print command interpreter 203 and the print medium side detected by the inserted side detecting means 207 are the same. Data can thus be printed to a desired specific side of the print medium because the printer 10 can reliably print to the print medium side specified by the host 220.

  • Patent number: 6633404
    Abstract: In order to efficiently utilize a memory in a digital copying machine which reads image data from an original and stores the read image data, whether or not to store image data in the memory is determined when the image data is read or the image data is input through an external interface. For example, image data read by an image reader is stored while data from an external device which is input through the external interface is not stored. This is because when the digital copying machine is used as an external device printer, the owner of the image data is difficult to identify and therefore the image data is not to be stored in the memory.

  • Patent number: 6628417
    Abstract: This invention provides a service which allows the user of the client apparatus that submits a print request to preview an image to be printed, and can reduce the information volume with the client apparatus to achieve quick response, and prints a high-quality image with the requested size. For this purpose, a center server (102) on the network stores and manages display image data, and transfers requested display image data upon receiving a request from a client computer. Upon receiving a request including a print size from the client computer, the center server sends the print size and information that specifies an image to an image server which saves high-resolution images. Upon receiving the information, the image server processes high-resolution image data to have the designated size, and sends back the processed image data to the center server. The center server sends the received image data to a print server to make it print the data.

  • Patent number: 6624911
    Abstract: A printer that stores a minimal number of unadjusted stochastic threshold arrays in non-volatile memory, in which the unadjusted threshold arrays are used to generate adjusted threshold arrays at run time by use of Transfer Function Tables (TFT's). The unadjusted array for a particular color is stored in the printer's ROM and preferably is stored in a packed configuration to save memory space. The TFT's are used to convert the unadjusted threshold data into adjusted threshold data for each color and type of print media. In a preferred embodiment, the unadjusted threshold array comprises a 128 row by 128 column sized array, and each element of this array comprises a 10-bit number. When the TFT is applied to this unadjusted array, the resulting numeric values for the adjusted array elements are produced as 8-bit numeric values. The greater precision in the originating unadjusted array provides more perceptual levels of intensity (i.e.

  • Patent number: 6621589
    Abstract: A central print system in which print jobs are directed to a particular print resource based on a set of print job attributes specified by an end user at the time the print job is submitted. The central print system provides intent-based printing which allows the end user to specify the end result of the printing operation rather than initially selecting a print resource. A print job manager processes the print job using the end user selected print job processing attributes to select the appropriate print resource from a group of networked print resources. An attribute registers a set of job processing attributes for each print resource servicing a single print queue and provides a list of available print job attributes to each client computer on the network from which an end user specifies particular job attributes to define a desired end result for a print job. The attribute manager periodically updates the job processing attribute list as print resources are added to or deleted from the network.
