1. A printing device configured to print an image over a plurality of pages on a first surface of a printing medium having a long belt shape, the printing device comprising:
a conveyance unit configured to convey the printing medium;
a printing unit configured to print an image by ejecting ink on the first surface of the printing medium conveyed by the conveyance unit;
a fixing unit configured to fix an image printed on the first surface of the printing medium by the printing unit to the printing medium; and
a control unit,
wherein the control unit includes:
a printing control unit configured to control operation of the printing unit; and
a conveyance control unit configured to control operation of the conveyance unit,
wherein the printing control unit includes a printing interruption control unit configured to control, when a printing interruption cause occurs, the printing unit to interrupt printing operation after completing printing of a printing-interruption-time last page being printed on the first surface of the printing medium, and further printing a position mark indicating a printing resumption position on a printing resumption page that is a next page of the printing-interruption-time last page,
wherein the conveyance control unit includes a conveyance speed control unit configured to control, after interruption of printing operation, the conveyance unit to start deceleration of a conveyance speed of the printing medium and stop a conveyance of the printing medium,
wherein the conveyance speed control unit controls the conveyance unit so that the printing-interruption-time last page is conveyed to the fixing unit when causing the conveyance unit to stop the conveyance of the printing medium,
wherein the conveyance control unit includes a rewinding control unit configured to control the conveyance unit so that the printing medium is rewound after fixing processing on the printing-interruption-time last page by the fixing unit is completed, and
wherein the rewinding control unit controls the conveyance unit so that the printing medium is rewound until a distance from the printing resumption position of the printing resumption page to the printing unit becomes equal to or longer than an acceleration distance required to obtain a conveyance speed that allows the printing resumption page to be printed, before the conveyance of the printing medium is resumed for printing resumption after printing operation is interrupted.
