Abstract: A print apparatus comprises a memory for storing compressed print information of at least two or more pages transmitted from a host computer, and executes image formation by extracting the compressed print information read from the memory. When nonconformity between an image size of the page to which the print apparatus is executing the image formation and a paper size fed for the relevant page is detected, the compressed print information, for the page in execution of the image formation, subsequent to the read address on the memory at a point of time of the nonconformity detection is read from the memory, and then extracted and abandoned. Thus, the read address on the memory indicates the head of a page subsequent to the page in execution of the image formation.

Abstract: A printing control method and device for receiving and processing print data including a security level, includes determining the security level of the print data when a predetermine fault occurs during printing processing of the print data and performing different fault recovery processing of the print data in accordance with the determined security level.

Abstract: An image forming apparatus having a display unit which displays system information and job information on such as a job execution state, comprising: a storage unit which stores in plural kinds of languages the job information displayed on the display unit; a job storage unit which stores plural jobs being executed and on standby; a language type extracting unit which extracts language types registered in the jobs from the jobs stored in the job storage unit; and a display control unit which acquires from the storage unit the job information in a language matching the language type extracted by the language type extracting unit, and displays on the display unit the job information on the job stored in the job storage unit by using the acquired display information.

Abstract: An image forming method that is capable of interpreting a plurality of image forming processes includes a setting step of setting an image forming process that is activated by the image forming method, and an issuing step of issuing a manufacturer identifier and machine-type identifier and process identification information representing the image forming process set in the setting step.

Abstract: A method using a printing system comprising a controller programmed for rendering imposed documents given media cost considerations is described. The method includes steps of: evaluating a print job; evaluate media loaded within printer; and determining media print options including cost. Additionally, embodiments enable user selection of printing option prior to the printing system or rendering the print job or selecting a printing option based on user profile. The print job is then rendered.

Abstract: An image processing apparatus having an arithmetic processing section for quantizing multi-density level image data and converting the image data into digital halftone image data for outputting. The arithmetic processing section is configured to create a plurality of quantized patterns to determined a dot occurrence information sequence, based on a given initial quantized pattern, such that anti-correlation is increased with respect to the dot occurrence information sequence for a pixel that has already been quantized; to add the plurality of quantized patterns to form a dither mask; and to quantize the multi-density level image data by using the dither mask.

Abstract: A copying apparatus detects as to whether or not an IC chip is present in an original paper. When the IC chip is detected, the copying apparatus reads data from this IC chip. When the read data is additional information, which can be printed as an image, the copying apparatus stops a printing process, and notifies a message indicating that the read data is the additional information to the user and then, waits for an instruction issued by the user. When the user instructs to print the additional information, the copying apparatus prints the image read from the original paper and the additional information read from the IC chip on a printing paper in an output format designated by the user.

Abstract: A method for calibrating an imaging apparatus configured for scanning a document, the imaging apparatus including a scanner head having an illuminant and a sensor, and a phosphorescent material forming a phosphorescent area located opposite the scanner head, the method including at least one of performing an ambient light calibration based on a background light emission intensity level of the phosphorescent area; performing an ambient light time calibration based on a decay constant of the phosphorescent material; performing a horizontal calibration to compensate for irregularities in at least one of the illuminant and the sensor across a width of the phosphorescent area; and performing a vertical calibration to compensate for changes of scanning speed of the scanner head in a lengthwise scanning direction along a length of the phosphorescent area.

Abstract: A method and system to convert an electronic image file described in a page description language containing both contone and non-contone image objects to an intermediate binary format image. The intermediate format image separately encodes the contone and non-contone image objects. The contone image objects are edge-tagged. Prior to printing, the intermediate binary format page image is separated into the contone and non-contone image objects. The contone image objects are converted back to a contone form using the edge tagging to modify the filter weights of a digital filter. The non-contone image objects are converted to contone form by means of a pattern matching scheme.
