Abstract: Minimum density pixels are always turned OFF. Maximum density pixels are always turned ON. The binary conversion errors obtained along the main scanning direction based on the maximum and minimum density pixels are subjected to modification processes with using the correction value “a”. Thus, binary conversion errors are gradually converted into the non-uniform value pattern IE[pos]. Accordingly, uniform conversion errors will not be distributed to pixels along each main scanning line. The leading edge S of the middle density region will not receive uniform conversion errors. Turned-On pixels will be generated properly non-uniformly, thereby preventing occurrence of any undesirable textures.

Abstract translation: 最小密度像素总是关闭。 最大密度像素总是打开。 基于最大和最小密度像素沿主扫描方向获得的二进制转换误差使用校正值“a”进行修改处理。 因此，二进制转换错误逐渐转换为非均匀值模式IE [pos]。 因此，不会将均匀的转换误差分配给沿着主扫描线的像素。 中密度区域的前缘S将不会得到均匀的转换误差。 开启的像素将被非常均匀地生成，从而防止出现任何不希望的纹理。

Abstract: When a subject pixel has been turned OFF, an accumulated error value is calculated based on binary conversion. Then, the sum of the accumulated error value and the binary conversion error for the subject pixel is compared with a predetermined value. When the sum is less than the predetermined value, the binary conversion error for the subject pixel is multiplied with a coefficient so that the absolute value of the binary conversion error is decreased. Then, the absolute-decreased error is distributed to unprocessed neighboring pixels according to an error distribution matrix. Then, the binary conversion error for the subject pixel is stored in a working memory as a binary conversion error for the s-th pixel to be used in the process of the next pixel.

Abstract: In the printer of the type in which the spacing between a print head and a sheet of paper supported on a platen can be adjusted depending upon the sheet used, the position in which the spacing is adjusted is freely selectable. When printing is effected on a sheet with tab labels, the position of the print head is specified so that the print head confronts the tab label, and then the spacing between the print head and the face of the print sheet is adjusted upon moving the print head to the specified position.

Abstract: A print controller is provided for generating dot data, which specifies a dot formation state and which is to be provided to a printing unit. The printing unit is configured to execute, based on the dot data, dot-forming operations to form dots in dot rows extending in a prescribed direction by moving a print head in the prescribed direction while ejecting ink droplets from nozzles in the print head and to print an image by repeatedly executing the dot-forming operation to form a plurality of dot rows juxtaposed in a direction orthogonal to the prescribed direction. The print controller includes: a printing width determining unit; a density data generating unit; and a dot data generating unit. The printing width determining unit determines a printing width value corresponding to a working distance of the print head in the prescribed direction. The density data generating unit generates density data specifying ink densities related to the quantity of ink for each pixel based on image data specifying a gradation value for each pixel and based on the printing width value, the density data generating unit generating the density data so that an upper limit on a tolerable ink density per pixel grows smaller as the working distance of the print head in the prescribed direction corresponding to the printing width value grows shorter. The dot data generating unit generates dot data by executing a halftone process on the density data generated by the density data generating unit.
