An example method comprises identifying a plurality of supply levels corresponding to a set of print supplies of a print device. The example method further comprises coordinating depletion of the set of print supplies by selecting between black print and process black print for a print job of the print device based on the plurality of supply levels.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to and detachable from the discharge port member and to be capable of opening and closing the discharge port; a liquid stop valve provided inside the discharge port member; and a protrusion provided inside the cover portion and configured to open the liquid stop valve in closing the cover portion. In the liquid storage container, the storage portion is sealable by at least one of a first sealing portion formed of a contact portion between the cover portion and the discharge port member and a second sealing portion formed of the liquid stop valve, and the first sealing portion and the second sealing portion are configured to be simultaneously unsealed.

In one example in accordance with the present disclosure, a refill container is described. The refill container includes a reservoir to house a volume of print compound and a chamber to house a pressurized fluid. A wall separates the reservoir from the chamber. A pressure release device of the refill container creates a fluid path between the chamber and the reservoir such that the pressurized fluid flows into the reservoir to mix with the volume of print compound. A trigger of the refill container activates the pressure release device.

A liquid jetting apparatus includes a casing, a tank formed with a liquid storage chamber which stores liquid, an inlet which allows the liquid to be poured into the liquid storage chamber, and a liquid outflow channel which allows the liquid to flow out from the liquid storage chamber, a conveying mechanism which conveys a recording medium along a conveying path extending in a front-rear direction, a carriage which moves in a left-right direction, and a head mounted on the carriage and having a nozzle which jets the liquid onto the recording medium conveyed by the conveying mechanism. The tank, the conveying path, and the carriage are arranged inside the casing, the tank is arranged outside the conveying path in the left-right direction, and at least a part of the tank is arranged inside both ends of a movement area of the carriage in the left-right direction.

A device to supply printing material to a printing material container of a printing apparatus may includes a chamber to store the printing material, a printing material outlet portion through which the printing material stored in the chamber is to be discharged, a plunger head to move in the chamber to discharge the printing material stored in the chamber through the printing material outlet portion, and a plunger handle disengaged from the plunger head and to engage the plunger head to move the plunger head to discharge the printing material.

Examples of a print particle replenishment device are described herein. Some examples of the print particle replenishment device may include an interfacing portion. Some examples of the interfacing portion may include a ramp to actuate a hinging door. In some examples, the hinging door may be on a host device receptacle.

A printing apparatus and an ink refill method thereof are provided. The printing apparatus may comprise a printing unit performing printing, and an ink filling unit filling ink in the printing unit in an upward manner, wherein the printing unit includes a printing ink receptor accommodating ink, a spray head spraying the ink, and a pressure controller controlling a pressure of a fluid for operation of the ink, and the ink filling unit includes a supply ink receptor filled with ink for supply to the printing unit, and an ink supply unit mounted on the spray head to supply the ink supplied from the supply ink receptor to the spray head.

An ink cartridge includes a main body, a head part, a first hole, a label, and a second hole. The main body stores ink. The head part is provided on the main body and has a plurality of nozzles for ejecting ink. The first hole has a tapered shape which narrows from an outer side toward an inner side of the main body, and a needle for supplying ink to the main body is inserted into the first hole. The label in a film shape is attached to the main body. The second hole is provided at the label and overlaps the first hole in a plan view of the label. The second hole guides the needle to the first hole when the needle is inserted.

A system for printing an imprint on a flat material includes a cartridge holding a consumable (e.g. ink) and at least one material processing device (MPD) (e.g. franking machine) having a printer and a data processor connected to the printer to control use of the cartridge to produce the imprint. The MPD is configured to detect insertion of the cartridge into the printer and generate current consumption information representing the use of the cartridge by the printer since insertion. The cartridge can include a first non-volatile memory that (unchangeably) stores a unique cartridge identification of the cartridge. The data processor is configured to: cause, based on a predeterminable usage-relevant event occurring, a current use-information, generated based on the current consumption information logically linked to the cartridge identification, to be stored in a second memory, and write to an irreversibly writable memory area of the first memory when the event occurs.

A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.
