Recording apparatus for carrying out high-density dot printing |
摘要 |
A recording apparatus has an array of recording elements arranged in a main scanning direction and having a predetermined dot pattern, and forms a dot image on a recording medium located opposite to the recording elements. Reception circuit receives image data of a predetermined dot density. A plurality of line buffers store one dot line of data of interest as a printing target among the image data and aligned in the main scanning direction, and plural dot lines of data preceding and following the one dot line with respect to a sub-scanning direction. A compensation data generating circuit converts the one dot line of data of interest as the printing target into N lines of compensation data, divided by N with respect to the sub-scanning direction, based on the plural dot lines of data preceding and following the one dot line. A control circuit controls the time for activating the recording elements based on the compensation data. Recording will therefore be accomplished with a dot recording density in the sub-scanning direction different from the dot density of the image data.
