Abstract: The recording head is formed with ejection holes including first ejection holes and second ejection holes arranged in a first direction. A recording medium has invisible columns extending in the first direction and invisible rows extending in a second direction orthogonal to the first direction. The invisible columns have first invisible columns and second invisible columns alternately arranged in the second direction. The scanning unit performs a first scan and a second scan in the second direction. The controller prevents the recording head in the first scan from ejecting ink droplets from the first ejection holes onto the first invisible columns and from the second ejection holes onto the second invisible columns, and prevents the recording head in the second scan from ejecting ink droplets from the first ejection holes onto the second invisible columns and from the second ejection holes at the first invisible columns.

Abstract: In the control device, the generating portion generates control data to be used by the controlling portion to form a specific image. The generating portion generates the control data such that in a first case where the printing execution unit forms the end image, the head drive portion drives the print head to eject ink droplet only from nozzles classified into the downstream nozzle group toward the downstream end region, that in a second case where the printing execution unit forms the center image the head drive portion drives the print head to eject ink droplet from the plurality of nozzles including the upstream and downstream nozzle groups toward the center region, and that, in the first case, the first nozzle does not eject ink droplet toward the center region for forming a specific part, and such that in the second case, the second nozzle ejects ink droplet for forming the specific part.

The recording unit is disposed between the first feeding member and the second feeding member to eject a plurality of ink droplets onto the recording medium fed between the first feeding member and the second feeding member. A plurality of ink droplets ejected onto the recording medium forms a plurality of raster lines extending in a main-scanning direction orthogonal to the feeding direction.

Abstract: An image processing device to generate coded image data, which represents an image to be printed in a printing apparatus, is provided. The image processing device includes a data generator to downscale tone values of pixels included in the image, the tone values of pixels being included in a predetermined scale range, and assign a plurality of types of codes having different lengths to the downscaled tone values to generate image data, and a data transmitter configured to transmit the coded image data to the printing apparatus. The data generator downscales the tone values of pixels by classifying each tone value of pixels into one of segments, which are unevenly delimited by predetermined thresholds within the predetermined scale range and include a larger segment and a smaller segment, and assigning a code with a shorter bit length to the tone value classified into the larger segment.

Abstract: The recording head is formed with ejection holes including first ejection holes and second ejection holes arranged in a first direction. A recording medium has virtual columns extending in the first direction and virtual rows extending in a second direction orthogonal to the first direction. The virtual columns have first virtual columns and second virtual columns alternately arranged in the second direction. The scanning unit performs a first scan and a second scan in the second direction. The controller prevents the recording head in the first scan from ejecting ink droplets from the first ejection holes onto the first virtual columns and from the second ejection holes onto the second virtual columns, and prevents the recording head in the second scan from ejecting ink droplets from the first ejection holes onto the second virtual columns and from the second ejection holes at the first virtual columns.

Abstract: A data processing device is connected to a web data providing unit that provides web data via a network. The web data has at least one of first web data and second web data corresponding to the first web data. A screen reader can be installed on the data processing device. The displaying unit displays the web data. The screen reader voices the first web data displayed on the displaying unit and fails to voice the second web data displayed on the displaying unit. The acquiring unit acquires the web data from the web data providing unit. The determining unit determines, based on visually impaired information indicating that the user is a visually impaired, whether or not the acquiring unit should acquire the first web data from the web data providing unit even if the user instructs the acquiring unit to acquire the second web data from the web data providing unit.

Abstract: A data processing device includes a displaying unit, a receiving unit, a determining unit, and a controlling unit. The displaying unit displaying one of a first operation screen and a second operation screen. Input data is inputted into the receiving unit by a user. The determining unit determines, based on at least one of the input data and settings of an OS, which of the first operation screen and the second operation screen should be displayed on the displaying unit. The controlling unit controls the displaying unit to display the first operation screen if the determining unit determines that the first operation screen should be displayed on the displaying unit, and control the displaying unit to display the second operation screen if the determining unit determines that the second operation screen should be displayed on the displaying unit.

Abstract: A data processing device includes a displaying unit, a user type determining unit, and a display controlling unit. The display unit displays display data including first display data for visually impaired users and second display data for sighted users. The user type determining unit determines whether a user is visually impaired or sighted. The display controlling unit controls the displaying unit to display the first display data when the user type determining unit determines that the user is visually impaired, and to display the second display data when the user type determining unit determines that the user is sighted.

Abstract: A print method and apparatus for minimizing effects of error in repositioning during printing process may include generating successive scans of a recording head, wherein the scans may partially overlap to account for the error in repositioning. As an example, after the recording head makes one scan across the document being printed, the document (or the head) may be repositioned for the next scan so that several print elements of the recording head are aligned to lie between certain rows of dots printed in the previous scan, resulting in a higher number of rows in the overlapping portion of the scans. Additional features may include varying the row/column arrangement of dots in the overlap portion, or performing error diffusion and correction for different areas of resolution in the scans.

The image forming apparatus still further includes a auxiliary-scanning unit configured to scan the recording head, relative to the recording medium, in a main scanning direction perpendicular to the auxiliary-scanning direction.
