Abstract
A tape printer is presented to improve the print quality of a border portion between print areas. Dots, which are smaller in area than dots printed in a previous print area, are printed after being shifted by α (1.0 dot) in the X direction from dots printed in an overlap area. Accordingly, even if the dots are printed slightly out of position, high-density overlap portions, where dots overlap with each other, and/or paper surface-exposed portions, where dots are away from each other, are not produced greatly or distributed unevenly.
Claims24
A printing device, comprising:
- a print head having a plurality of printing elements which are aligned in a column direction, the print head being movable in a row direction relative to a medium;
- and
- a print controller that generates a print signal which drives the printing elements to form dots on the medium,
- wherein the print controller generates the print signal so that dots are formed over a predetermined area of a previous print area, the dots in the predetermined area being smaller than dots in the other portion of the previous print area, and the dots formed over the predetermined area being shifted by a predetermined amount in a predetermined direction from dots previously formed in the predetermined area, wherein the predetermined direction is the row direction.
A printing device, comprising:
- a print head having a plurality of printing elements which are aligned in a column direction, the print head being movable in a row direction relative to a medium;
- and
- a print controller that generates a print signal which drives the printing elements to form dots on the medium,
- wherein the print controller generates the print signal so that dots are formed over a predetermined area of a previous print area, the dots in the predetermined area being smaller than dots in the other portion of the previous print area, and the dots formed over the predetermined area being shifted by a predetermined amount in a predetermined direction from dots previously formed in the predetermined area, wherein the predetermined direction is the column direction, and wherein the predetermined amount by which the dots are shifted is 0.5 dot in the column direction from the dots previously formed in the predetermined area.
A storage medium for storing programs, the programs controlling a printing device that includes a print head having a plurality of printing elements which are aligned in a column direction, the print head being movable in a row direction relative to a medium;
- the programs further comprising:
- a program for generating a print signal which drives the printing elements so that dots are formed over a predetermined area of a previous print area, the dots in the predetermined area being smaller than dots in the other portion of the previous print area, and the dots formed over the predetermined area being shifted by a predetermined amount in a predetermined direction from dots previously formed in the predetermined area, wherein the predetermined direction is the row direction.
A storage medium for storing programs, the programs controlling a printing device that includes a print head having a plurality of printing elements which are aligned in a column direction, the print head being movable in a row direction relative to a medium;
- the programs further comprising:
- a program for generating a print signal which drives the printing elements so that dots are formed over a predetermined area of a previous print area, the dots in the predetermined area being smaller than dots in the other portion of the previous print area, and the dots formed over the predetermined area being shifted by a predetermined amount in a predetermined direction from dots previously formed in the predetermined area, wherein the predetermined direction is the column direction, and wherein the predetermined amount by which the dots are shifted is 0.5 dot in the column direction from the dots previously formed in the predetermined area.
A method for printing using a printing device that includes a print head having a plurality of printing elements which are aligned in a column direction, the print head being movable in a row direction relative to a medium, comprising:
- generating a print signal which drives the printing elements so that dots are formed over a predetermined area of a previous print area, the dots in the predetermined area being smaller than dots in the other portion of the previous print area, and the dots formed over the predetermined area being shifted by a predetermined amount in a predetermined direction from dots previously formed in the predetermined area, wherein the predetermined direction is the row direction.
