1. A printing apparatus that performs image-printing by thermally transferring inks of multiple colors applied to an ink ribbon onto a printing medium in a superimposed manner, the printing apparatus comprising:
an image-printing unit that transfers at least one color of the inks of multiple colors applied to the ink ribbon onto a printing medium;
an interface that supplies power from an outside to the printing apparatus;
a battery;
a conveyance unit that conveys a printing medium to an image-printing start position, at which the image-printing unit starts transferring at least one color of the inks of multiple colors onto the printing medium, using power from the battery or the interface; and
a control unit that
performs, before conveyance of a printing medium is started by the conveyance unit, a first determination to determine whether a remaining battery level of the battery is equal to or more than a first threshold,
in a case where the remaining battery level is equal to or more than the first threshold as a result of the first determination, causes the conveyance unit to convey the printing medium by power from the battery,
in a case where the remaining battery level is less than the first threshold as a result of the first determination and the printing apparatus is supplied with power from the interface, charges the battery with power from the interface, causes the conveyance unit to convey the printing medium, and performs, after the printing medium reaches a predetermined position, a second determination to determine whether a remaining battery level of the battery is equal to or more than a second threshold, and
in a case where the remaining battery level is equal to or more than the second threshold as a result of the second determination, starts image-printing processing to cause the image-printing unit to transfer the inks of multiple colors onto the printing medium.
