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.

摘要： A printer having storing means storing time information indicating the time at which cleaning operations were last performed, with the initial value of time information stored in the storing means being set to a time later than the shipment of the printer. Elapsed time between the time information stored in the storing means and the current time is calculated when a user gives the printer an instruction to start printing operations. The printer performs suitable cleaning operation for a case wherein the calculated value of the elapsed time is negative.

摘要： An inkjet printing apparatus is provided which minimizes the amount of inks consumed for preventing the sedimentation of ejected inks on the platen ink absorber and which can effectively prevent the sedimentation of inks. To this end, a comparison is made between the ejected volume of easily sedimenting inks and the ejected volume of sedimentation restraining inks in terms of ink components. If the ejected volume of the sedimentation restraining inks is found not enough, a required amount of sedimentation restraining ink is additionally ejected.

摘要： The inkjet printer can discharge a bubble in an ink flow path while suppressing ink consumption. Ink in an ink tank is supplied to a printing head through a flow path and filter. Bubbles in the flow path and printing head are discharged by applying a negative pressure to an ejection port of the printing head. At this time, after a first negative pressure has been applied to the ejection port with an on/off valve provided between the ink tank and the filter being closed, the on/off valve is opened to discharge the ink from the ejection port. Further, after that, a second negative pressure at a level that makes it difficult for a bubble to pass through the filter is applied to the ejection port to discharge a bubble present at a location, which is closer to the printing head than the filter is to printing head, from the ejection port together with the ink.

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.
