Abstract
A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.
