A printing apparatus comprising: a printing unit configured to execute printing on a medium; a heating unit configured to cause the medium on which printing has been executed to be heated; and a controller configured to control the heating unit, wherein the controller is configured to employ, as a heating mode in which the heating unit is caused to heat the medium, a steam-use heating mode in which heating is executed using steam and a steam-nonuse heating mode in which heating is executed without using steam, wherein the heating unit is configured to employ, as the steam-use heating mode, a steam heating mode in which the medium is caused to be heated using steam at a temperature lower than a boiling point of 100°C and a superheated-steam heating mode in which the medium is caused to be heated using steam at a temperature not lower than the boiling point of water, wherein the heating unit includes: a storing section configured to store water; a first heater configured to heat the water being stored in the storing section; characterised in that the heating unit further includes: an opening portion through which a fluid used for heating the medium is discharged; an opening/closing section provided between the storing section and the opening portion, the opening/closing section being configured to open and close a flow channel of the fluid; and a second heater provided between the opening/closing section and the opening portion, wherein the controller is configured to cause the opening/closing section to be in an open state and activate the first heater and inactivate the second heater, to thus control the heating unit as the steam heating mode, and to cause the opening/closing section to be in an open state and then activate both the first heater and the second heater, to thus control the heating unit as the superheated-steam heating mode. a printing unit configured to execute printing on a medium; a heating unit configured to cause the medium on which printing has been executed to be heated; and a controller configured to control the heating unit, wherein the controller is configured to employ, as a heating mode in which the heating unit is caused to heat the medium, a steam-use heating mode in which heating is executed using steam and a steam-nonuse heating mode in which heating is executed without using steam, wherein the heating unit is configured to employ, as the steam-use heating mode, a steam heating mode in which the medium is caused to be heated using steam at a temperature lower than a boiling point of 100°C and a superheated-steam heating mode in which the medium is caused to be heated using steam at a temperature not lower than the boiling point of water, wherein the heating unit includes: a storing section configured to store water; a first heater configured to heat the water being stored in the storing section; characterised in that the heating unit further includes: an opening portion through which a fluid used for heating the medium is discharged; an opening/closing section provided between the storing section and the opening portion, the opening/closing section being configured to open and close a flow channel of the fluid; and a second heater provided between the opening/closing section and the opening portion, wherein the controller is configured to cause the opening/closing section to be in an open state and activate the first heater and inactivate the second heater, to thus control the heating unit as the steam heating mode, and to cause the opening/closing section to be in an open state and then activate both the first heater and the second heater, to thus control the heating unit as the superheated-steam heating mode. a storing section configured to store water; a first heater configured to heat the water being stored in the storing section; characterised in that the heating unit further includes: an opening portion through which a fluid used for heating the medium is discharged; an opening/closing section provided between the storing section and the opening portion, the opening/closing section being configured to open and close a flow channel of the fluid; and a second heater provided between the opening/closing section and the opening portion, wherein an opening portion through which a fluid used for heating the medium is discharged;
