20090009543 | Liquid Ejecting Apparatus and Liquid Ejecting Method - A liquid ejecting apparatus includes a plurality of nozzles that eject a liquid, a sensor that detects a defective nozzle in which defective ejection occurs when the liquid is to be ejected, a recovery mechanism that recovers the defective nozzle to its normal state so as to enable the liquid to be normally ejected from the defective nozzle, and a control unit that, when a defective nozzle is detected, compares a method, in which the liquid is ejected after the defective nozzle is recovered to its normal state by the recovery mechanism, with a method, in which the liquid is ejected without using the defective nozzle, while the defective nozzle is not recovered to its normal state, and controls the liquid to be ejected by using the method having a shorter processing time. | 01-08-2009 |
20120163731 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM - An image processing device specifies the number of pixels m for securing a delay time for preventing an error diffusion process from being performed at pixels of the (N+1)-th line in which diffusion of errors from a pixel of N-th line (N is a natural number) of image data is not completed, performs a control of starting an error diffusion process of the (N+1)-th line of the image data after the error diffusion process of the m-th pixel for the N-th line of the image data, and performs the error diffusion process for each line of the image data. | 06-28-2012 |
20120200627 | PRINT DATA GENERATION DEVICE, PRINT DATA GENERATION METHOD, AND PRINT DATA GENERATION PROGRAM - To suppress misalignment of a line formation position resulting from main scans being performed with different timings. A printer is made to perform a printing action of acquiring image data, printing a line during an N | 08-09-2012 |
20120229539 | PRINTER AND CONTROL METHOD THEREOF - A printing head in which a plurality of nozzles is formed is moved in a predetermined direction, and is caused to execute main scanning in which the ink is ejected from the plurality of nozzles, in which the printing head performs printing another line in Nth main scanning between lines which are printed in the N-1th main scanning or prior thereto, performs printing a unit of printing which is configured by a plurality of lines in Nmax main scannings, and controls an amount of ink which is ejected from the printing head so that the ejecting amount of ink may be controlled so that the amount of ink ejected in Nmax-th main scanning is larger than that in the main scanning of Nmax-1th time or prior thereto, even if data items denoting the amount of ink for each pixel are the same as each other. | 09-13-2012 |
20120229864 | PRINTING DATA GENERATING APPARATUS, PRINTING DATA GENERATING METHOD, AND PRINTING DATA GENERATING PROGRAM - A printing data generating apparatus acquires image data; classifies, upon causing a printer to execute a printing process for printing a line in an N-th main scanning operation between lines printed in (N−1)-th or earlier main scanning operations and printing a print unit formed with a plurality of lines by performing Nmax main scanning operations, pixels on the plurality of lines into groups based on the image data such that each group includes the pixels that are to be printed in the same main scanning operation; identifies, among the groups, the group with the highest ink usage for printing the pixels of the group based on the image data; and generates, based on the image data, printing data for causing the printer to print an image represented by the image data by printing the pixels of the group with the highest ink usage in the Nmax-th main scanning operation. | 09-13-2012 |
20130100492 | PRINTING SYSTEM AND DATA TRANSFER METHOD - A printing system provided with a printer and a host computer which transfers image data to the printer includes a data transfer unit configured to transfer the image data as image data of a first data format in the case where a connection between the printer and the host computer is first connection means, and transfer the image data as image data of a second data format in the case where a connection between the printer and the host computer is second connection means, wherein the second connection means has less data communication amount per unit time than the first connection means, and when given image data is transferred, image data of the second data format, corresponding to the given image data, has less data amount than image data of the first data format, corresponding to the given image data. | 04-25-2013 |
20130128307 | PRINTING DEVICE AND PRINTING METHOD OF PRINTING DEVICE - The printing device has a data generating section (controller section) which conducts image processing with a plurality of processors to generate dot data for printing from image data; and a printing section that conducts printing to a printing medium based on the dot data sent from the data generating section. The data generating section has a first processing mode that conducts processing to first image data that is a part of image data using N processors, and a second processing mode that conducts processing to second image data that is a part of image data using M processors, with N and M representing the number of the processors. N and M are natural numbers which are different from each other. The first processing mode and the second processing mode are determined depending on complexity of the image data. | 05-23-2013 |
