摘要： An ink jet printing apparatus that can inhibit the possible degradation of image quality caused by variation in the conveyance amount of a print medium is provided. The ink jet printing apparatus includes a detection section detecting the conveyance amount of the print medium, and a print head position adjusting section slightly moving a print head in a conveyance direction of the print medium. The print head position adjusting section adjusts the position of the print head in the conveyance direction according to an error in the conveyance amount of the print medium detected by the detection section. Thus, printing can be performed at the head position adjusted with the error in conveyance amount taken into account. Therefore, the possible degradation of the image quality caused by a conveyance variation can be inhibited.

摘要： A recording apparatus having a plurality of interfaces capable of communicating with external devices performs recording based on recording data input through any one of the plurality of interfaces. The recording apparatus determines which interface is used for receiving the recording data from the plurality of interfaces, and performs conversion processing on the recording data by increasing the amount of data in accordance with the determination result of which interface is used for receiving the recording data. The conversion processing changes depending on whether or not the interface used for receiving the recording data is an interface having a relatively high transfer rate (high speed interface).

摘要： The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.

摘要： In a printing apparatus using a printhead having an array of printing elements in which a plurality of printing elements are arranged in a predetermined direction, the printing apparatus performing printing by scanning the printhead over a printing medium in a direction crossing to the predetermined direction on the basis of information transmitted from a host apparatus, print data transmitted from the host apparatus is stored in a buffer, printing by the scanning is started when the print data stored in the buffer reaches a first amount that is smaller than an amount of print data to be printed on the printing medium by the printhead by one scanning, the scanning is interrupted when storage of the print data in the buffer is delayed during the scanning, and when, after the interruption, subsequent print data stored in the buffer reaches a second amount, the interrupted scanning is executed to complete printing by one scanning. Accordingly, with an inexpensive arrangement having a memory whose capacity is smaller than the data amount to be printed by one main scanning, interruption of printing/scanning can be suppressed, and even when printing/scanning is interrupted halfway, high-quality printing can be performed.

摘要： Printing of a unit pixel (1/D=1/600) in 4-pass printing (64 nozzles, and a total sheet supply amount of 62/600 in four operations) is exemplified in an image printing apparatus capable of printing a uniform, high-quality image while avoiding printing of a visually nonuniform image in multipass printing of two or more passes. With an image printing apparatus as described herein, satellites can be uniformly printed on the right and left of a unit pixel.

摘要： The present invention provides an inkjet recording apparatus and a method of detecting a remaining amount of ink capable of detecting an amount of ink remaining in an ink tank without the need of a special mechanism and part in an inkjet recording apparatus for recording an image by mounting the ink tank and a recording head on a carriage and scanning the carriage. The position where the carriage stops is detected by an encoder by moving the carriage by driving a motor and stopping the drive of the motor after the carriage constantly moves at a predetermined speed. The amount of ink remaining in the ink tank mounted on the carriage is determined based on the moving distance of the carriage from the time the drive of the motor is stopped to the time the carriage moved by inertia stops.

摘要： A preliminary process for ejecting an ink after ejecting a processing liquid on a printing medium and a post-process for ejecting the processing liquid after ejecting the ink on the printing medium are distinguished. In one preferred mode, when a preliminarily process portion, in which an ink dot is formed after formation of a processing liquid dot, and a post-process portion, in which the processing liquid dot is formed after formation of the ink dot are present in admixing fashion, an ejection amount of the ink per unit area in the post-process portion is made smaller than the ejection amount of the ink per unit area in the preliminarily process portion. By this, a difference of printing quality in the preliminarily process portion and the post-process portion on the printing medium can be made smaller.
