Abstract: A draft size detecting function detects a size and a setting direction of a draft set in a scanner which reads an image of the draft, a display unit displays, in a selectable state, an icon corresponding to the draft setting direction detected by the draft size detecting function, and displays, in a non-selectable state, an icon which does not correspond to the draft setting direction detected by the detecting function among a plurality of icons to designate a direction of the image in the draft, and the image direction corresponding to the selected icon is set as the direction of the image in the draft, in a case where the specific icon is selected from the selectable icons displayed in the display unit.

Abstract: A facsimile driver program recorded in a program recording medium is installed in a client device for a user to enter the type of process requested of a multifunction device. A first transmission unit transmits a command to the multifunction device asking for a screen corresponding to the entered type of process. Using the facsimile driver program, a user can make appropriate selections so that, even when the multifunction device has a plurality of server functions, the user is not required to go through needless operations.

Abstract: Hand-held printing device and systems adapted to receive radio signal information indicative of a position. Hand-held printing device having at least one antenna and a controller adapted to calculate the relative position of the hand-held printing device by comparing received radio signals on the antennae. Methods for using the same.

Abstract: A print control apparatus which transmits print data to a printing apparatus according to a print instruction for a logical printer. The print control apparatus includes a logical printer information management unit which manages logical printer information that is provided for each logical printer and is used to store information including a network address of a printing apparatus corresponding to a logical printer, a printing apparatus search unit which searches for printing apparatuses connected to a network, and a print data transmitting unit which transmits print data to a network address of a printing apparatus found by the printing apparatus search unit if no network address corresponding to a logical printer specified in a print instruction is registered in the logical printer information.

Abstract: A printing support system for reducing an environmental load that changes an input load of a print operation depending on data representing the environmental load includes: an environmental load calculation basis information storage unit that stores environmental load calculation basis information used to calculate the data representing the environmental load; a print request input unit through which a print request including a print setting is input; an environmental load calculation unit that calculates the data representing the environmental load on the basis of the print request input by the print request input unit and the environmental load calculation basis information stored in the environmental load calculation basis information storage unit; a print operation input unit through which a print operation for instructing to start printing is input; and a determination unit that, when it is determined that the print operation through the print operation input unit has been input more than a predetermined

Abstract: An image forming apparatus includes an image data input unit configured to take in image data, an image data memory unit configured to save image data, a data output unit configured to output the image data in a specific format, and an image data erasing unit configured to erase the image data saved in the image memory unit after output processing by the data output unit is completed. The image data erasing unit requests the user to make a selection as to whether or not an erasing manipulation for image data as an erasure object is executed, and erases the image data by an erasing method at a different security level according to the selection in response to a selection request.

Abstract: A workflow scheduler is provided in which highly correlated processes are scheduled so as to be continuously executed. The workflow scheduler analyzes an input print order, divides the print order into a plurality of processes to carry out the print order, arranges a schedule of the plurality of processes divided, groups a set of processes together from the plurality of processes into which the print order is divided according to grouping attributes of the plurality of processes, the set of processes being associated with each other by the grouping attributes, outputs the plurality of processes whose schedule is arranged by the schedule arranging unit in a recognizable manner, and arranges the schedule of the plurality of processes such that the set of processes is capable of being executed continuously.

Abstract: An image forming engine has color shifting amount storage units C, M, Y, and K (black) which store actual shifting amounts relative to ideal scan directions on image carriers C, M, Y, and K in image forming units C, M, Y, and K. Color shifting correction amount arithmetic units calculate color shifting correction amounts for respective color components to base on the stored color shifting amounts. Color shifting correction units C, M, Y, and K perform color shifting correction by converting coordinates upon reading out image data from bitmap memories C, M, Y, and K on the basis of the calculated color shifting correction amounts, and then perform tone correction. Data after tone correction undergo halftone processing by halftone processors. C, M, Y, and K to suppress moire. PWM processors C, M, Y, and K generate PWM signals for scanning, and output them to exposure units C, M, Y, and K of the respective image forming units.

Abstract: In accordance with the present invention, a system and method are described for producing pure gray tones on a multi-color document output device that includes a system for operating on device independent color data having multiple color components, which color data corresponds to one or more associated electronic documents. The system and method function to extract gray data by the use of tristimulus values in a range specified by a functional relationship of a selected tristimulus value.

Abstract: In accordance with the present invention, a system and method are described for producing pure gray tones on a multi-color document output device that includes a system for operating on device independent color data having at least three color components, which color data corresponds to one or more associated electronic documents. The system and method function to extract grayscale data from such a device independent color data description, which grayscale corresponds to a rendering and a single color space. Such resultant data, inclusive of a color data portion and a grayscale portion, is thus completed in device independent form.

Abstract: According to the present invention, a printing system comprises a conversion unit which performs conversion processing for print data by using a filter module specified by filter information attached to the print data; a history storage unit which stores filter information for specifying the filter module used by said conversion unit; and a filter re-designation unit which reads out the filter information stored by said history storage unit and attaches the filter information to the print data.

Abstract: An original document feed tray is positioned above an original document output tray. When original documents are set on the original document feed tray, the original document feed tray is moved upwardly from a home position to a position where the uppermost original document sheet can be transported to an original document transport mechanism. When the original document feed tray is lifted in accordance with the reduction of the original documents on the original document feed tray after the original documents are transported to the original document transport mechanism, the original document feed tray is lifted to a position, above the position where all original documents on the original document feed tray were transported to the original document transport mechanism.

Abstract: A method for improving print quality by using lossless image compression (JPEG-LS) technology and system thereof are provided. The detailed characteristics of prediction errors generated during lossless image compression encoding or decoding process are retrieved and fed back to a halftone print mode of the printer and are used to adjust the halftone print mode.
