Abstract

An embodiment of the present invention is directed to reducing problems in double-sided printing using roll paper. An apparatus in the embodiment includes a unit configured to cause a print unit to print on a roll-shaped print medium based on a received job for roll paper, a unit configured to control drive upon printing on the roll-shaped print medium, and a unit configured to cause a cutting unit to cut the roll-shaped print medium after printing the first surface of the roll-shaped print medium. The apparatus controls drive based on a first drive parameter for suppressing a first sheet-floating upon printing on the first surface of the roll-shaped print medium, and controls drive based on a second drive parameter for suppressing a second sheet-floating upon printing on the second surface of a cut print medium.

First claim

What is claimed is:

1. A print control apparatus comprising:
a reception unit configured to receive a job of printing for a roll-shaped print medium or a job of printing for a cut print medium;
a first feeding unit configured to feed the roll-shaped print medium if a job of printing for a roll-shaped print medium is received by said reception unit;
a second feeding unit configured to feed the cut print medium if a job of printing for a cut print medium is received by said reception unit;
a print control unit configured to cause a print unit to print an image on the roll-shaped print medium, a cut roll-shaped print medium or the cut print medium based on the job received by said reception unit; and
a drive control unit configured to control a predetermined drive, based on a drive parameter,
wherein after said print control unit causes the print unit to print an image on a first surface of the roll-shaped print medium, said print control unit causes the print unit to print an image on a second surface of the cut roll-shaped print medium, the cut roll-shaped print medium being obtained by cutting the roll-shaped print medium, and the second surface of the cut roll-shaped print medium being opposite to the first surface of the cut roll-shaped print medium on which the image has been printed, and
said drive control unit controls the predetermined drive based on a first drive parameter upon printing on the first surface of the roll-shaped print medium fed from said first feeding unit, controls the predetermined drive based on a second drive parameter different from the first drive parameter upon printing on the second surface of the cut roll-shaped print medium, and controls the predetermined drive, based on a third drive parameter different from the first drive parameter and the second drive parameter upon printing on the cut print medium fed from said second feeding unit.

2. The apparatus according to claim 1 , further comprising the print unit.

3. The apparatus according to claim 1 , further comprising a display unit configured to display an instruction for a user to place the cut roll-shaped print medium in the second feeding unit.

4. The apparatus according to claim 1 , wherein the drive control unit controls a suction of the print medium based on a first suction amount upon printing on the first surface of the roll-shaped print medium, controls the suction of the print medium based on a second suction amount larger than the first suction amount upon printing on the second surface of the cut roll-shaped print medium, and controls the suction of the print medium based on a third suction amount smaller than the second suction amount upon printing on the cut print medium.

5. The apparatus according to claim 1 , wherein the drive control unit controls a conveyance of the print medium
pulse upon printing on the first surface of the roll-shaped print medium, controls the conveyance of the print medium
based on a second conveyance pulse smaller than the first conveyance pulse upon printing on the second surface of the cut roll-shaped medium, and controls the conveyance of the print medium based on a third conveyance pulse smaller than the first conveyance pulse upon printing on the cut print medium.

6. The apparatus according to claim 1 , wherein the drive control unit controls at least one of a suction of the print medium, a conveyance of the print medium and a height of a printhead, based on the drive parameter.

7. The apparatus according to claim 1 , wherein the drive control unit controls the predetermined drive based on the first drive parameter that is changed in accordance with a type of the roll-shaped print medium upon printing on the first surface of the roll-shaped print medium, controls the predetermined drive based on the second drive parameter that is changed in accordance with a type of the cut roll-shaped print medium upon printing on the second surface of the cut roll-shaped print medium, and controls the predetermined drive based on the third drive parameter that is changed in accordance with a type of the cut print medium upon printing on the cut print medium.

8. A control method executed in a print control apparatus having a first feeding unit configured to feed a roll-shaped medium if a job of printing for the roll-shaped print medium is received by the print control apparatus and a second feeding unit configured to feed a cut print medium if a job of printing for the cut print medium is received by the print control apparatus, the method comprising:
receiving the job of printing for the roll-shaped print medium or the job of printing for the cut print medium;
causing a print unit to print an image on the roll-shaped print medium, a cut roll-shaped print medium, or the cut print medium based on the received job; and
controlling a predetermined drive, based on a drive parameter,
wherein in the printing by the print unit, after the print unit is caused to print an image on a first surface of the roll-shaped print medium, the print unit is caused to print an image on a second surface of the cut roll-shaped print medium, the cut roll-shaped print medium being obtained by cutting the roll-shaped print medium, and the second surface of the cut roll-shaped print medium being opposite to the first surface of the cut roll-shaped print medium on which the image has been printed, and
the predetermined drive is controlled based on a first drive parameter upon printing on the first surface of the roll-shaped print medium fed from the first feeding unit, the predetermined drive is controlled based on a second drive parameter different from the first drive parameter upon printing on the second surface of the cut roll-shaped print medium, and the predetermined drive is controlled based on a third parameter different from the first drive parameter and the second drive parameter upon printing on the cut print medium fed from the second feeding unit.

9. The method according to claim 8 , further comprising displaying an instruction for a user to place the cut roll-shaped print medium in the second feeding unit.

10. The method according to claim 8 , wherein a suction of the print medium is controlled based on a first suction amount upon printing on the first surface of the roll-shaped print medium,
the suction of the print medium is controlled based on a second suction amount larger than the first suction amount upon printing on the second surface of the cut roll-shaped print medium, and
the suction of the print medium is controlled based on a third suction amount smaller than the second suction amount upon printing on the cut print medium.

11. The method according to claim 8 , wherein a conveyance of the print medium is controlled based on a first conveyance pulse upon printing on the first surface of the roll-shaped print medium,
the conveyance of the print medium is controlled based on a second conveyance pulse smaller than the first conveyance pulse upon printing on the second surface of the cut roll-shaped medium, and
the conveyance of the print medium is controlled based on a third conveyance pulse smaller than the first conveyance pulse upon printing on the cut medium.

12. The method according to claim 8 , wherein at least one of a suction of the print medium, a conveyance of the print medium and a height of a printhead is controlled based on the drive parameter.

13. The method according to claim 8 , wherein the predetermined drive is controlled based on the first drive parameter that is changed in accordance with a type of the roll-shaped print medium upon printing on the first surface of the roll-shaped print medium,
the predetermined drive is co
