In general, the ink supply method for the printer is a method of directly mounting a factory pre-manufactured cartridge directly to the printer, and a method of directly or indirectly supplying ink separately from the outside without depending on the cartridge for the ink consumed in the printer. This is known.

It is a well-known and convenient way to mount the cartridge directly to the printer and supply it. However, when the ink is quickly exhausted, especially in the case of a color cartridge, when the ink of one color is used up, the entire cartridge is replaced even if the remaining ink remains. Because of this, the cost of using the ink is greatly increased.

In order to reduce the cost of using the ink, a method of indirectly supplying ink through a tube in a general container is used. This indirect method can drastically reduce the use cost of ink when the ink in the container is exhausted, by pouring the ink into the container and reusing the ink.
