Abstract:
1. A printing device that prints an image on a recording sheet, comprising: a sheet feeding mechanism that feeds said recording sheet by a predetermined amount at a time; a carriage that is movable, substantially at a constant speed, in a direction substantially perpendicular to a sheet feeding direction; a print head mounted on said carriage, said print head capable of simultaneously forming a plurality of print lines when said carriage moves; a controller that controls operations of said sheet feeding mechanism, said carriage and said print head, wherein said controller controls said print head to print a first print pattern that is formed by a part of said plurality of print lines which are on an upstream side with respect to the sheet feed direction, wherein said controller controls said sheet feeding mechanism to feed said recording sheet after said first pattern is formed, wherein said controller controls said print head to print a second print pattern that is formed by a part of said plurality of print lines which are on a downstream side with respect to the sheet feed direction after the recording sheet is fed by said predetermined amount in such a manner that at least a part of the first print pattern overlaps a part of the second print pattern, having a predetermined positional relationship with the part of the second print pattern with respect to a direction perpendicular to the sheet feed direction, wherein the part of the second print pattern deviates from the predetermined positional relationship with respect to a direction perpendicular to the sheet feed direction when the print head is inclined with respect to the sheet feed direction.
