Ink container and system
An ink container includes a main body, a lower surface, and a guide wall. The main body includes a chamber configured to store ink. The main body has first and second sidewalls spaced apart from one another to define a first width. The supply port faces frontward in an attachment direction of the ink container and is configured to supply ink from the chamber. The lower surface is positioned above the supply port in an up-down direction, and forward of the supply port in the attachment direction of the ink container.

11 . The ink container of claim 1 , further comprising
an electrical interface positioned upward of the guide wall.
12 . The ink container of claim 1 , further comprising
a guide groove that extends in the attachment direction along one of the first sidewall or the second sidewall of the main, wherein
the guide groove is positioned upward of a lower end of the guide wall.
13 . The ink container of claim 1 , further comprising
a first wall that extends downward from the lower surface; and
a second wall that extends downward from the lower surface, wherein
the guide wall is positioned between the first wall and the second wall.
14 . The ink container of claim 1 , further comprising
a first member having the supply port;
a second member positioned frontward of the first member in the attachment direction and having the lower surface and the guide wall,
wherein the first member is movable relative to the second member.
15 . A printing system comprising:
an attachment unit; and
an ink container configured to be attached to the attachment unit, the ink container comprising:
a main body including a chamber configured to store ink, the main body having first and second sidewalls spaced apart from one another to define a first width;
a supply port facing frontward in an attachment direction of the ink container and configured to supply ink from the chamber;
a lower surface positioned above the supply port in an up-down direction, and forward of the supply port in the attachment direction of the ink container; and
a guide wall defining a second width smaller than the first width, wherein:
the guide wall has a front end positioned forward of the supply port and rearward of a front end of the ink container in the attachment direction,
the guide wall has a lower end positioned above of the supply port and below the lower surface in the up-down direction, and
the guide wall has a first guide surface positioned inward from the first sidewall of the main body and an opposing second guide surface positioned inward of the second sidewall of the main body such that the guide wall and each of the first and second guide surfaces is positioned within the first width defined by the first and second sidewalls.
16 . The printing system of claim 15 , wherein the attachment unit includes:
an attachment space configured to receive the ink container;
a receiving portion that defines an opening receiving the guide wall when the ink container is received in the attachment space.
17 . The printing system of claim 16 , wherein the attachment unit further includes
a second biasing member configured to apply an upward biasing force to the guide wall when the ink container is received in the attachment space.
18 . The printing system of claim 16 , wherein the receiving portion comprises a slot that receives the guide wall when the ink container is received in the attachment space.
19 . The printing system of claim 18 , wherein the attachment unit includes first and second protruding pieces protruding upwardly from a surface of the attachment unit, wherein the first and second protruding pieces are spaced apart from one another to form the slot that receives the guide wall when the ink container is received in the attachment space.
20 . An ink container comprising:
a main body including a chamber configured to store ink, the main body having first and second sidewalls spaced apart from one another to define a first width;
