摘要： Provided is a print position control method whereby displacement of a print position in a wide range can be corrected very accurately, without reducing a printing speed or increasing a manufacturing cost. Thus, a printing apparatus includes: a first correction unit, for correcting a print position at accuracy equal to the resolution of the printing apparatus; and a second correction unit, for correcting the print position at accuracy higher than the resolution and in the range of an area that corresponds to one pixel of the resolution. With this arrangement, the print position displacement in a wide range equal to or greater than one pixel can be corrected by the first correction unit, and a print position displacement smaller than one pixel can be corrected by the second correction unit. Therefore, correction of a print position displacement in a wide range is enabled at a higher accuracy.

摘要： A print buffer for storing recording data is divided into a plurality of segments and the amount of recording data causing a recording head to perform a recording operation is counted on a segment-by-segment basis. A recording medium is compared to the print buffer with respect to a scanning direction of the recording head and segments not corresponding to the inside of the recording medium are selected from the plurality of segments. The amount of recording data included in the selected segments and causing a recording operation to occur is counted and added up to estimate the amount of ink ejected outside the recording medium.

摘要： Image deterioration is suppressed as much as possible which is complexly generated by variations of printing positions respectively of printing elements in a printing element row and by displacement of printing positions among printing element rows. To this end, a first adjustment value for adjusting printing positions among a plurality of printing elements included in a printing element row is obtained. Next, printing positions among a plurality of printing elements are adjusted based on the first adjustment value. Then a second adjustment value for adjusting printing positions among not less than two of the printing element rows is obtained. Thereby variations of printing positions in a discharge port row and displacement of printing positions among discharge port rows are properly adjusted in different phases, and adverse effects generated by two kinds of different causes are collectively suppressed.

摘要： A recording device drives a recording head mounted on a carriage while main-scanning by moving the carriage in a direction generally orthogonal to the sheet-feeding direction of a sheet. The recording device drives a first nozzle of the recording head at an upstream side in the sheet-feeding direction of the sheet to form a first dot pattern while scanning the carriage and drives a second nozzle at a downstream side in the sheet-feeding direction of the sheet to form a second dot pattern. The recording device feeds a region where the first dot pattern is recorded to a position facing the second nozzle. The second dot pattern is recorded in a region where the first dot pattern is not recorded.

摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

摘要： There is provided a printing apparatus capable of printing input data in proper adaptation to plural types of printing data input units and environments of use. For this purpose, the type of an input unit is first recognized. For example, when it is recognized that a personal computer capable of causing the printing apparatus to perform a setting process for registration is connected, it is judged that the process has already been performed, and a mode for printing at a high speed is adopted. When it is recognized that a digital camera is connected, since it is likely that the process has not been performed yet, a mode for printing at a low speed is adopted to prevent any reduction in image quality.
