First Claim
1. A printing apparatus comprising:
- a carry mechanism performing a carry operation of carrying a medium in a predetermined direction;
a print head performing, in alternation with said carry operation, a printing operation of printing an image by forming dots on said medium while moving in a direction intersecting said predetermined direction, said print head having a first dot formation section and a second dot formation section that are provided at positions that are offset from one another in said predetermined direction and that respectively form dots of different colors as said dots; and
a controller for printing said image with said print head in a first resolution and in a second resolution that is lower than said first resolution based on data of pixels constituting said image to be printed,wherein, when said image is to be printed in said second resolution, said controller causes said first dot formation section and said second dot formation section to form the respective dots, on different positions on said medium, based on data of the same pixel,wherein, when said image is to be printed in said first resolution, said controller causes said first dot formation section and said second dot formation section to form the respective dots, on a same position on said medium, based on data of the same pixel.
