Abstract: A controller acquires image recording data for recording a plurality of passes; determines a first movement distance of a carriage for recording each of the plurality of passes; determines a non-usage ratio that is a ratio of a number of unused nozzles in a last pass of the plurality of passes to a total number of the plurality of nozzles arranged in a conveyance direction; determines a second movement distance in a particular pass which is recorded before the last pass, the second movement distance being a movement distance of the carriage assuming that the particular pass is recorded without using nozzles of a first ratio smaller than or equal to the non-usage ratio; and in response to determining that the second movement distance is shorter than the first movement distance, performs image recording of the particular pass without using the nozzles of the first ratio.

The controller carries out: acquiring a recording data, a front edge margin, and a tail edge margin, determining whether or not at least one of first and second reference values is less than a threshold value, and a positioning process. When at least one of the first and second reference values is less than the threshold value, then the controller carries out: a front edge detecting process, a first recording preparation process, and a recording process. When at least one of the first and second reference values is not less than the threshold value, then the controller carries out: a second recording preparation process, and the recording process.

Abstract: A printing apparatus includes a print execution section and a controller. The print execution section includes: a printing head having nozzles from which ink is discharged; a main-scan section configured to execute main-scan in which the printing head moves along a main-scan direction relative to a printing medium; and a sub-scan section configured to execute sub-scan in which the printing medium moves along a sub-scan direction relative to the printing head. The controller obtains object image data indicating an object image formed by pixels, generates pieces of partial printing data by processing the object image data in an order from a downstream side toward an upstream side in the sub-scan direction, and causes the print execution section to execute, a plurality of times, the sub-scan and partial printing in which ink is discharged from the printing head during the main-scan by use of the pieces of partial printing data.

Abstract: A printer includes a print head and a controller. The controller is configured to, using first print data containing a plurality of layers, select at least one, but not all, of the plurality of layers based on weight information regarding respective weights of the plurality of layers, generate second print data based on the selected at least one but not all of the plurality of layers, and control the print head to print at least one patch image on a printing medium based on the generated second print data.

Abstract: An image forming system, having a recording head, a sheet conveyer, an inverting mechanism, and a controller, is provided. The sheet conveyer conveys a sheet in a sheet-conveying direction. The sheet is nipped at nipping points located at positions upstream and downstream in the sheet-conveying direction with respect to a discharging position. The inverting mechanism inverts the sheet from a first side to the second side. The controller determines an initial arrangement of the sheet in the sheet conveyer where image-forming on the second side starts, and controls a length of a period between time, when image-forming on the first side of the sheet in the posture with the first side facing the recording sheet is completed, and time, when the image-forming on the second side of the sheet inverted and refed to the sheet conveyer starts, based on the determined initial arrangement of the sheet in the sheet conveyer.

Abstract: A printer includes a print engine and a controller configured to, when a particular condition is satisfied, control the print engine to perform first partial printing to form first dots corresponding to a first portion of a target image without forming second dots corresponding to a second portion of the target image, perform sub scanning over a first distance after the first partial printing and before second partial printing, and perform the second partial printing to form the second dots without forming the first dots, and when the particular condition is not satisfied, control the print engine to perform the first partial printing to form at least a part of the first dots, perform the sub scanning over a second distance different from the first distance after the first partial printing and before second partial printing, and perform the second partial printing to form the second dots.

Abstract: A control device is configured to: obtain target image data; generate dot data using the target image data; and control a print execution device to print a print image using the dot data by executing: a first partial printing of forming the dots in an overlapping area and a first non-overlapping area; and a second partial printing of forming the dots in the overlapping area and a second non-overlapping area. The control device generates data of the dot data corresponding to the overlapping area by executing an overlapping area processing including first processing for values of pixels within a first range and second processing for values of pixels within a second range, the first processing including lowering a density of an image to be printed in the overlapping area.
