1. A printing apparatus comprising:
a main body having an accommodation part configured to accommodate a printing medium;
an opening/closing cover supported by the main body so as to be swingable between a closed position and an opened position, the opening/closing cover covering the accommodation part in a case the opening/closing cover is in the closed position, the opening/closing cover opening the accommodation part in a case the opening/closing cover is in the opened position, the opening/closing cover including:
a guide wall being a part of the opening/closing cover, the guide wall having a first surface and a second surface, the first surface and the second surface being opposite,
the first surface being configured to guide the printing medium to be discharged from the printing apparatus,
the second surface facing an inside of the printing apparatus in the case the opening/closing cover is in the closed position, and
the second surface having an installation part,
the installation part being configured to respectively receive both, at respective times, one of a first unit and a second unit that are selectively installable, the second unit being different from the first unit,

the first unit including:
a first unit platen roller configured to discharge the printing medium from the printing apparatus; and
a partition wall configured to guide the printing medium to be discharged by the first unit platen roller,

the second unit including:
a second unit platen roller configured to discharge the printing medium from the printing apparatus; and

a print head configured such that:
in a case the installation part of the second surface of the guide wall receives the first unit,
in the case the opening/closing cover is in the opened position, the print head is configured to be disposed at a position not to face the first unit platen roller,
in the case the opening/closing cover is in the closed position,
the print head is configured to be disposed at a position facing the first unit platen roller of the first unit, and
the print head is configured to perform printing on the printing medium while nipping the printing medium together with the first unit platen roller; and

in a case the installation part of the second surface of the guide wall receives the second unit,
in the case the opening/closing cover is in the opened position, the print head is configured to be disposed at a position not to face the second unit platen roller,
in the case the opening/closing cover is in the closed position,
the print head is configured to be disposed at a position facing the second unit platen roller, and
the print head is configured to perform the printing on the printing medium while nipping the printing medium together with the second unit platen roller,

wherein the installation part is further configured such that:
in a case the installation part of the second surface of the guide wall receives the first unit,
the first surface of the guide wall is covered by the partition wall of the first unit, and
in the case the opening/closing cover is in the opened position, the partition wall is configured to guide the printed printing medium to be discharged from the printing apparatus; and

in a case the installation part of the second surface of the guide wall receives the second unit,
a part of the first surface of the guide wall is uncovered by the second unit, and
in the case the opening/closing cover is in the closed position, the uncovered part of the first surface of the guide wall is configured to guide the printed printing medium to be discharged from the printing apparatus.
