Abstract

A printing apparatus, having a printing unit, includes a first holding unit, a conveyance unit, a first cutting unit arranged between the printing unit and the first holding unit, a second cutting unit arranged between the printing unit and the first cutting unit, and a control unit. The first holding unit holds a sheet. The conveyance unit conveys the sheet to the printing unit. The first cutting unit cuts the sheet fed from the first holding unit. The second cutting unit cuts the sheet fed from the first holding unit. The control unit determines, in accordance with a length in a conveyance direction of a product to be printed on the sheet by the printing unit, whether to cut the sheet fed from the first holding unit by the first cutting unit or the second cutting unit.

First claim

What is claimed is:

1. A printing apparatus having a printing unit, the printing apparatus comprising:
a first holding unit configured to hold a sheet;
a conveyance unit configured to convey the sheet to the printing unit;
a first cutting unit arranged between the printing unit and the first holding unit and configured to cut the sheet fed from the first holding unit;
a second cutting unit arranged between the printing unit and the first cutting unit and configured to cut the sheet fed from the first holding unit; and
a control unit configured to determine, in accordance with a length in a conveyance direction of a product to be printed on the sheet by the printing unit, whether to cut the sheet fed from the first holding unit by the first cutting unit or the second cutting unit.

2. The printing apparatus according to claim 1 , further comprising a second holding unit configured to hold the sheet at a position different from the first holding unit,
wherein the control unit controls the second cutting unit so as to cut the sheet fed from the second holding unit.

3. The printing apparatus according to claim 2 , wherein the control unit controls the first cutting unit and the second cutting unit so that trimming of a leading edge of the sheet fed from the first holding unit will be performed by the first cutting unit and trimming of a leading edge of the sheet fed from the second holding unit will be performed by the second cutting unit.

4. The printing apparatus according to claim 2 , wherein, when accepting a printing instruction, the control unit determines whether to print on the sheet fed from the first holding unit, and controls the conveyance unit to feed the sheet fed from the first holding unit in accordance with the determination.

5. The printing apparatus according to claim 4 , further comprising a notification unit configured to perform notification to prompt a user to set a sheet to the first holding unit in a case in which the control unit has determined to print on the sheet fed from the first holding unit.

6. The printing apparatus according to claim 1 , wherein, in a case in which the length in the conveyance direction of the product is greater than a length of a conveyance path from the first cutting unit to the conveyance unit, the first cutting unit is controlled so that the first cutting unit will cut the sheet fed from the first holding unit.

7. The printing apparatus according to claim 6 ,
wherein the conveyance unit includes a plurality of conveyance rollers, and
wherein, in a case in which the length in the conveyance direction of the product is greater than a length of a conveyance path from the first cutting unit to a conveyance roller closest to the printing unit, the first cutting unit is controlled so that the first cutting unit will cut the sheet fed from the first holding unit.

8. The printing apparatus according to claim 7 , wherein the length of the conveyance path from the first cutting unit to the conveyance roller closest to the printing unit is a length of a conveyance path from the first cutting unit to the conveyance roller closest to the printing unit including a loop of the sheet formed between the conveyance roller and the first cutting unit.

9. The printing apparatus according to claim 1 , wherein, in a case in which the length in the conveyance direction of the product is greater than a dimension of one of a plurality of sheet sizes, the first cutting unit is controlled so that the first cutting unit will cut the sheet fed from the first holding unit.

10. A printing apparatus comprising:
a first storing unit;
a second storing unit;
a conveyance unit;
a control unit; and
a printing unit,
wherein the first storing unit includes a first holding unit configured to hold a sheet, and includes a first cutting unit, where the first cutting unit is arranged between the printing unit and the first holding unit and is configured to cut the sheet fed from the first holding unit,
wherein the second storing unit includes a second holding unit configured to hold a sheet, and includes a second cutting unit, where the second cutting unit is arranged between the printing unit and the first cutting unit and configured to cut the sheet fed from the first holding unit and the sheet fed from the second holding unit,
wherein the conveyance unit is configured to convey, to the printing unit, one sheet fed from the first holding unit and the sheet fed from the second holding unit, and
wherein, in a case in which the sheet is to be fed from the first holding unit, the control unit determines, in accordance with a length in a conveyance direction of a product, whether to cut the sheet fed from the first holding unit by the first cutting unit or the second cutting unit.
