ABSTRACT:
A recording apparatus for recording images in the form of a multiplicity of dots, including a print head having a linear array of dot-forming elements for forming dots along a straight line, a supporting device for supporting a recording medium in facing relation with the print head, a feeding device for feeding the recording medium and the print head relative to each other in a feeding direction which intersects the straight line of dots, and a control device for controlling the dot-forming elements to effect a primary recording operation for recording a plurality of primary lines according to respective sets of primary line data, such that the primary lines are equally spaced from each other in the feeding direction. The control device controls the dot-forming elements to also effect a secondary or supplemental recording operation for recording at least one secondary line between adjacent two lines of the plurality of primary lines, according to secondary line data. The secondary line data is prepared based on at least one of the two sets of primary line data which represent the adjacent two primary lines, respectively, such that the secondary lines improve a quality of the images recorded on the recording medium.
