摘要： A printing apparatus receives, from a host apparatus, main scanning/printing direction information representing the main scanning/printing direction of a printhead. The printing apparatus stores, in a print buffer, print data corresponding to the printing direction represented by the main scanning/printing direction information generated by the host apparatus. The CPU of the printing apparatus controls printing by the printhead on the basis of the main scanning/printing direction information and the print data stored in the print buffer.

摘要： A recording apparatus is provided with two or more kinds of sub-scanning amounts per main scan, and records a high quality image by reducing the bleeding between colors created characteristically by a multi-pass recording method. The number of times of main scanning to complete an image by a first discharge port array for black ink use and a second discharge port array for color ink use, respectively, are set to be m (m is a positive integer) and n (n is a positive integer) times. With respect to discharge ports to be used for recording in the first and second discharge port arrays, a distance between discharge ports which are positioned at upstream ends of the respective first and second discharge port arrays in the sub-scan direction is made equal to a length of a continuously conveying amount of (m+a) (a is a positive integer) times by combination of the at least two kinds of conveying amounts.

摘要： This invention reduces an unprinted stripe occurred by edge deviation of a printhead. An inkjet printing apparatus according to this invention can execute a first printing mode in which an image is printed by scanning the printhead in a first region on the printing medium N times and scanning the printhead in a second region adjacent to the first region (N+1) times, and a second mode in which an image is printed by scanning the printhead in the first region M times and scanning the printhead in the second region (M+1) times. The width, in the conveyance direction of the printing medium, of the second region printed in the second printing mode is narrower than the width, in the conveyance direction of the printing medium, of the second region printed in the first printing mode.

摘要： To achieve high-quality printing by controlling an ink-traveling direction by an electrostatic force so that the ink can be accurately applied on a printing medium, the ink ejected to areas outside edges of the printing medium is prevented from being attracted to the end portions in margin-less printing. This configuration includes: a platen, made of a conductive material, positioned immediately below the printing medium; an absorber positioned at a side of the edge; and a mesh conductive member disposed on the absorber. A first voltage is applied to the platen, causing polarization in the printing medium, and a second voltage higher than the first voltage is applied to the conductive member. Thereby, ink ejected outside the edges in the margin-less printing, travels straight-forwardly toward the conductive member without being attracted to the end portions, and is absorbed into the absorber via the conductive member.

摘要： A printing apparatus performs printing by scanning a printhead having an array of printing elements in which a plurality of printing elements are arranged in a predetermined direction, over a printing medium according to control information and image data transmitted from a host apparatus. Setting information designating some of the printing elements to be used for printing in the printing elements in the printhead according to a predetermined printing parameter is transmitted as control information from the host apparatus to the printing apparatus in the printing apparatus, the printing elements to be used are set according to the setting information. Data to be printed by the printing elements used for printing in correspondence with scanning is generated in the host apparatus and transmitted as image data from the host. The printing apparatus performs printing by driving the set printing elements according to the image data during scanning. Control relating settings of printing parameters in the printing apparatus is thus simplified to effectively reduce the capacity of a memory and the number of gates of a logic circuit provided in the printing apparatus. The manufacturing cost and the size of the printing apparatus are thereby reduced.

摘要： A high-quality image is printed with reduced bleeding in colors that may appear at a boundary between a black image and a color image. A head for ejecting black ink and a head for ejecting color ink perform three times of scanning while feeding is carried out therebetween for moving the printing medium by four pitches of ejection openings arranged on the heads, different ejection openings are caused to correspond to a scanning area, which corresponds to the four pitches, and multi-pass printing is performed to complete printing on the area. The black head completes printing of the black image, and then, the color head completes printing of the color image adjacent to the black image. The arrangement of ejection openings is determined so that between last scanning for completing printing of the black image and the first scanning for printing of the color image, scanning with no performing printing exists.

摘要： When completing an image in a predetermined area by an odd or even number of bidirectional printing scans, this invention makes it possible to suppress lines of image defects and density variations and thereby print a high-quality image at high speed. In completing an image by an odd number of bidirectional printing scans, the print data for small ink droplets and large ink droplets are thinned using the first and second thinning pattern. The first and second thinning pattern thin the print data for small ink droplets and large ink droplets so that a difference between the total print ratio of all forward printing scans of the odd number of scans and the total print ratio of all backward printing scans of the odd number of scans when the first thinning pattern is used differs from that when the second thinning pattern is used.
