a printing cassette mountable on the housing by insertion to the cassette mounting opening in a first direction, wherein:

the first surface has:

a first area adjacent to the cassette mounting opening; and

a second area adjacent to the cassette mounting opening, the second area being opposite to the first area with respect to the cassette mounting opening in a second direction orthogonal to the first direction,

the first area and the second area are located upstream from the print head in a direction in which the printing cassette is mounted to the housing, and

in a state where the printing cassette is mounted on the housing, a portion of the printing cassette adjacent to the first area is located outside the housing beyond the first area in the first direction and a portion of the printing cassette adjacent to the second area is located outside the housing beyond the second area in the first direction.

2. The printer according to claim 1 , wherein:

the printing cassette includes a first roll into which a printing tape is wound, and

in a state where the printing cassette is mounted on the housing, at least a portion of the first roll is located outside the housing beyond the first area and the second area.

3. The printer according to claim 2 , wherein:

the printing cassette includes a case accommodating the first roll, and

in a state where the printing cassette is mounted on the housing, the printing tape is conveyed in the case in a direction toward an inside of the housing with respect to the first area and the second area in the first direction.

4. The printer according to claim 1 , wherein:

the printing cassette includes a second roll into which an ink ribbon is wound, and

in a state where the printing cassette is mounted on the housing, the second roll is located within a range of the housing not beyond the first area and the second area in the first direction.

5. The printer according to claim 1 , wherein:

the printing cassette includes a gear configured to transmit a driving force, and

in a state where the printing cassette is mounted on the housing, the gear is located within a range of the housing not beyond the first area and the second area in the first direction.

6. The printer according to claim 1 , wherein:

the first surface further has a third area and a fourth area, both of which are adjacent to the cassette mounting opening, the third area and the fourth area being located between the first area and the second area in the second direction,

the fourth area located opposite to the third area with respect to the cassette mounting opening in a third direction orthogonal to the first direction and the second direction, and

in a state where the printing cassette is mounted on the housing, a portion of the printing cassette adjacent to the third area is located outside the housing beyond the third area in the first direction and a portion of the printing cassette adjacent to the fourth area is located outside the housing beyond the fourth area in the first direction.

7. The printer according to claim 1 , further comprising a cover being openable and closable with respect to the housing,

wherein the cover contacts the first surface when the cover is closed.

8. The printer according to claim 1 , wherein the print head and the platen roller face each other in the second direction.

9. The printer according to claim 1 , wherein the first area, the second area, and the print head are located at respective positions such that a virtual plane passes through the first area, the second area, and the print head, the virtual plane extending parallel to the first direction.

10. A printer comprising:

a housing having a first surface having a cassette mounting opening;

a print head disposed in the housing, the print head extending toward the cassette mounting opening from an inside of the housing;

a platen roller disposed in the housing, the platen roller facing the print head; and

a printing cassette mountable on the housing by insertion to the cassette mounting opening in a first direction, wherein:

the first surface has:

a first area adjacent to the cassette mounting opening;

a second area adjacent to the cassette mounting opening, the second area being opposite to the first area with respect to the cassette mounting opening in a second direction orthogonal to the first direction,

the first area and the second area are located upstream from the print head in a direction in which the printing cassette is mounted to the housing, and

in a state where the printing cassette is mounted on the housing, the printing cassette protrudes outside the housing beyond the first area and the second area in the first direction.

11. A printer comprising:

a housing having a first surface having a cassette mounting opening;

a print head disposed in the housing, the print head extending toward the cassette mounting opening from an inside of the housing;

a platen roller disposed in the housing, the platen roller facing the print head; and

a printing cassette mountable on the housing by insertion to the cassette mounting opening in a first direction, wherein:

the printing cassette has a first side-surface and a second side-surface overlapping each other in a second direction orthogonal to the first direction, and

in a state where the printing cassette is mounted on the housing, at least a portion of the first side-surface and at least a portion of the second side-surface do not overlap the housing in the second direction.
