Abstract

A printing apparatus includes a conveyance unit arranged on an upstream side of a printing unit with respect to a conveyance direction of a print medium and configured to convey the print medium to the printing unit, and a control unit configured to, after a start of printing of the print medium by the printing unit, regulate the printing by the printing unit during a time when a leading edge of the print medium conveyed by the conveyance unit is passing through a set section preset on a conveyance path of the print medium.

First claim

What is claimed is:

1 . A printing apparatus comprising:
a conveyance unit arranged on an upstream side of a printing unit with respect to a conveyance direction of a print medium and configured to convey the print medium to the printing unit; a support unit configured to support, from a lower side, the print medium conveyed by the conveyance unit, the support unit including a platen section facing the printing unit, and a guide section extended from the platen section to a downstream side in the conveyance direction; and a control unit configured to, after a start of printing of the print medium by the printing unit, regulate the printing by the printing unit during a time when a leading edge of the print medium conveyed by the conveyance unit is passing through a set section preset on a conveyance path of the print medium, wherein, the guide section includes an inclined section inclined in a direction of approaching a support height of the print medium in the platen section to the downstream side in the conveyance direction, and the set section is a section including at least a part of the inclined section.

2 . The apparatus according to claim 1 , further comprising:
a discharge unit arranged on the downstream side of the printing unit in the conveyance direction and configured to discharge the print medium conveyed by the conveyance unit, wherein the set section includes a first set section and a second set section, the first set section is a section including at least a part of the inclined section, and the second set section is a section including a conveyance start position by the discharge unit.

3 . The apparatus according to claim 1 , wherein
setting and non-setting of the set section are switchable and are switched based on a print condition.

4 . The apparatus according to claim 1 , wherein
setting and non-setting of the set section are switchable and are switched based on a type of the print medium.

5 . The apparatus according to claim 4 , wherein
the type of the print medium includes a roll sheet or a cut sheet.

6 . The apparatus according to claim 4 , wherein
the type of the print medium includes a size of the print medium.

7 . The apparatus according to claim 1 , wherein
the print medium is a roll sheet, and setting and non-setting of the set section are switchable and are switched based on a winding diameter of the roll sheet.

8 . The apparatus according to claim 1 , wherein
setting and non-setting of the set section are switchable and are switched based on a temperature and/or a humidity of an installation environment of the printing apparatus.

9 . A control method of a printing apparatus including a conveyance unit arranged on an upstream side of a printing unit with respect to a conveyance direction of a print medium and configured to convey the print medium to the printing unit; and a support unit configured to support, from a lower side, the print medium conveyed by the conveyance unit, the support unit including a platen section facing the printing unit and a guide section extended from the platen section to a downstream side in the conveyance direction, the guide section including an inclined section inclined in a direction of approaching a support height of the print medium in the platen section to the downstream side in the conveyance direction, the method comprising:
after a start of printing of the print medium by the printing unit, regulating the printing by the printing unit during a time when a leading edge of the print medium conveyed by the conveyance unit is passing through a set section preset on a conveyance path of the print medium, wherein the set section is a section including at least a part of the inclined section.

10 . A non-transitory computer-readable storage medium storing a program configured to cause a computer to execute a control method of a printing apparatus including a conveyance unit arranged on an upstream side of a printing unit with respect to a conveyance direction of a print medium and configured to convey the print medium to the printing unit; and a support unit configured to support, from a lower side, the print medium conveyed by the conveyance unit, the support unit including a platen section facing the printing unit and a guide section extended from the platen section to a downstream side in the conveyance direction, the guide section including an inclined section inclined in a direction of approaching a support height of the print medium in the platen section to the downstream side in the conveyance direction, the control method comprising:
after a start of printing of the print medium by the printing unit, regulating the printing by the printing unit during a time when a leading edge of the print medium conveyed by the conveyance unit is passing through a set section preset on a conveyance path of the print medium,
wherein the set section is a section including at least a part of the inclined section.
