  • Publication number: 20240061628
    Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a plurality of users that use the printer. The server determines whether an unused stock, which is a stock that remains unused for a first period or longer, is present in a stock of cartridges held by each of the plurality of users. In a case in which it is determined that an unused stock is present in the stock held by a first user of the plurality of users, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server specifies a second user, of the plurality of users, to be provided with the unused stock, based on user stock data in which the stock of cartridges held by the user is registered, and on usage amount data indicating a usage amount of the cartridge.

  • Publication number: 20240059073
    Abstract: A cartridge providing system includes a printer ejecting a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to users that use the printer. Based on user stock data of each of the users, the server determines whether an unused stock, which is a stock that remains unused for a first period or longer from a start of holding, is present in a stock of the cartridges held by each of the users. If it is determined that an unused stock is present in the stock held by a first user, when a period until a usage expiry date of the unused stock is less than a first threshold value, the server sets a collection recommendation flag to the unused stock in the user stock data of the first user, the collection recommendation flag indicating the cartridge recommended for collection.

  • Publication number: 20240062154
    Abstract: A cartridge providing system includes a printer ejecting, onto a printing medium, a liquid (recording material) supplied from a cartridge, and a server managing provision of the cartridge to a user that uses the printer. The server manages user stock data, which is data associating a stock of the cartridges held by the user with usage expiry dates thereof, and vendor stock data, which is data associating a stock of the cartridges held by a sales company providing the cartridge to the user with usage expiry dates thereof. When the sales company provides the cartridge to the user, the server determines, based on the vendor stock data and the user stock data, the cartridge of which usage expiry date is to be provided from among the stock of the cartridges held by the sales company.
