1. A printing device comprising:
a first unit comprising a printing head configured to perform printing on a printing medium, the first unit having a plurality of outer surfaces; and
a second unit comprising a platen roller configured to nip the printing medium in cooperation with the printing head for printing and to convey the printing medium, the second unit having a plurality of outer surfaces,
wherein the first unit further has a first fixing member for fixing the first unit to an external housing, the first fixing member being provided at at least one of the plurality of outer surfaces of the first unit,
wherein the second unit further has a second fixing member for fixing the second unit to the external housing, the second fixing member being provided at at least one of the plurality of outer surfaces of the second unit,
wherein the first unit and the second unit can be assembled to each other and can be separated from each other,
wherein, in a state where the first unit and the second unit are assembled to each other, the printing head and the platen roller both extend in a first direction,
wherein the plurality of outer surfaces of the first unit comprises:
a first surface crossing the first direction;
a second surface crossing the first direction;
a third surface crossing a second direction crossing the first direction;
a fourth surface positioned opposite the third surface in the second direction;
a fifth surface crossing a third direction crossing both the first direction and the second direction; and
a sixth surface crossing the third direction,
wherein the plurality of outer surfaces of the second unit comprises:
a seventh surface crossing the first direction;
an eighth surface crossing the first direction;
a ninth surface; and
a tenth surface positioned on the same side as the sixth surface in the third direction in a state where the first unit and the second unit are assembled to each other,
wherein, in a state where the first unit and the second unit are assembled to each other, the first unit and the second unit form a discharge opening between the third surface and the ninth surface, the discharge opening allowing the printing medium to be discharged therethrough,
wherein the first fixing member is provided at each of the first surface, the second surface, the third surface, the fourth surface, the fifth surface, and the sixth surface, and
wherein the second fixing member is provided at each of the seventh surface, the eighth surface, the ninth surface, and the tenth surface.
