Abstract

A printing apparatus configured to perform printing on a sheet that is wound in a roll shape, the printing apparatus including: a feeding unit configured to feed a sheet that is drawn out of a roll sheet of a loaded sheet; a cut unit configured to cut the sheet fed by the feeding unit; and an operation unit configured to operate the feeding unit and the cut unit to function. The operation unit can operate the feeding unit and the cut unit to convey the sheet by an arbitrary amount and cut before the sheet is first printed.

First claim

What is claimed is:

1. A printing apparatus comprising:
a support unit configured to support a continuous sheet;
an operation unit configured to operate a conveyance unit to convey the continuous sheet in accordance with an operator's instruction;
a detection unit configured to detect that a continuous sheet has been loaded into the support unit;
a cut unit configured to cut the continuous sheet drawn from the support unit; and
a display control unit configured to cause a display unit to display an operation screen for prompting operations by the operation unit,
wherein in response to the detection by the detection unit that a continuous sheet has been loaded into the support unit, the display control unit causes the display unit to display the operation screen for prompting operations by the operation unit to selectively advance or reverse the continuous sheet before cutting the continuous sheet by the cut unit and before a printing on the continuous sheet is started.

2. The printing apparatus according to claim 1 , further comprising:
a reception unit configured to receive a print job; and
a printing unit configured to print the received print job, and
wherein the printing unit is configured to start printing the received print job, if the cut unit cuts the continuous sheet drawn from the support unit.

3. The printing apparatus according to claim 2 , wherein if the cut unit does not cut the continuous sheet during a predetermined time since the continuous sheet has drawn out, the printing unit prints the received print job.

4. The printing apparatus according to claim 1 , further comprising:
a reception unit configured to receive a print job; and
a printing unit configured to print the received print job,
wherein if the operation unit operates the conveyance unit in accordance with the operator's instruction, the printing unit does not print the received print job before the cut unit cuts the continuous sheet drawn from the support unit.

5. The printing apparatus according to claim 1 , wherein the continuous sheet is cut, if the operator presses a paper cut key to cut the continuous sheet at the cut position after conveying the continuous sheet in accordance with the operator's instruction.

6. The printing apparatus according to claim 1 , wherein the operation unit is configured to be capable of operating the conveyance unit so as to convey the continuous sheet to either advance or reverse for an arbitrary time.

7. The printing apparatus according to claim 1 , wherein the conveyance unit is configured to convey a leading edge of the continuous sheet drawn from the support unit to a predetermined position, and
wherein the operation unit is configured to operate the conveyance unit to convey the continuous sheet from the predetermined position by an arbitrary conveyance amount.

8. The printing apparatus according to claim 1 , wherein the continuous sheet is a roll sheet.

9. The printing apparatus according to claim 1 , wherein if the operation unit operates the conveyance unit in accordance with the operator's instruction, the cut unit automatically cuts the continuous sheet drawn from the support unit without any further instruction from an operator.

10. The printing apparatus according to claim 1 , wherein the operation unit operates at least one of the conveyance unit and the cut unit in accordance with the operator's instruction.

11. The printing apparatus according to claim 1 , wherein the operation screen includes a time to start printing.

12. The printing apparatus according to claim 1 , wherein after the continuous sheet being loaded into the support unit, the conveyance unit conveys a leading edge of the continuous sheet drawn from the support unit to a predetermined position, and then the operation unit causes the display unit to display the operation screen.

13. A printing apparatus comprising:
a support unit configured to support a continuous sheet;
an operation unit configured to operate a conveyance unit to convey the continuous sheet in accordance with an operator's instruction;
a detection unit configured to detect that of a continuous sheet has been loaded into the support unit;
a cut unit configured to cut the continuous sheet drawn from the support unit; and
a display control unit configured to cause a display unit to display an operation screen for prompting operations by the operation unit,
wherein in response to the detection by the detection unit that a continuous sheet has been loaded into the support unit, the display control unit causes the display unit to display, before cutting and printing the continuous sheet, the operation screen for prompting operations by the operation unit to input a conveyance distance for the sheet to be drawn from the support unit.

14. A printing apparatus comprising:
a support unit configured to support a continuous sheet;
an operation unit configured to operate a conveyance unit to convey the continuous sheet in accordance with an operator's instruction;
a detection unit configured to detect that a continuous sheet has been loaded into the support unit;
a cut unit configured to cut the continuous sheet drawn from the support unit; and
a display control unit configured to cause a display unit to display an operation screen for prompting operations by the operation unit,
wherein in response to the detection by the detection unit that a continuous sheet has been loaded into the support unit, the display control unit causes the display unit to display the operation screen for prompting operations by the operation unit to advance the continuous sheet by a conveyance amount, which is specified by the operator, before cutting the continuous sheet by the cut unit and before a printing on the continuous sheet is started,
wherein the operation unit is configured to have the conveyance amount input, and
wherein the conveyance unit is configured to perform conveyance from a predetermined position by the input conveyance amount.

15. A method of cutting a continuous sheet comprising:
detecting that a continuous sheet has been loaded into the support unit;
displaying an operation screen for prompting operations by the operation unit to selectively advance or reverse a continuous sheet before cutting the continuous sheet by a cut unit and before any printing on the continuous sheet is started in response to the detection that a continuous sheet has been loaded into a support unit;
conveying the continuous sheet by using the operation screen in accordance with the operator's instruction; and
cutting the continuous sheet drawn from the support unit with a cut unit.
