Abstract: An example of a device (100) may include a valve body (108). The device may include a printing substance transfer window (122) through the valve body (108). The device (100) may include a printing substance dispensing nozzle (110) rotatable within the valve body (108) between a first orientation with an orifice of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second orientation with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer window (122). The device (100) may include a dispensing-side gasket material (132) slideable against the internal face of the valve body (108) when rotating the printing substance dispensing nozzle (110) between the first orientation and the second orientation.

Abstract: Examples described herein relate to a print substance container consistent with the disclosure. For instance, the print substance container may comprise a print substance disposed inside of the print substance container and a first electromagnet formed of a wire coil positioned around the print substance container and extending along a length of the print substance container.

Abstract: A seal removal structure can include a shell and a piercing member. The shell can have a first end section and a second end section. The first end section can be configured to receive a supply conduit of a supply fluid container and the second end section can be dimensioned to receive a receiving conduit of a container device. Additionally, the piercing member can be provided within the first end section to penetrate a seal of the supply conduit when the supply conduit is received by the first end section. Moreover, the piercing member can incise at least a portion of the seal from the supply conduit when the supply conduit or the piercing member rotates, while the supply conduit is received by the first end section.

Abstract: Example implementations relate to an apparatus to transfer a quantity of print material to a printing device through a transfer mechanism. In some examples, the apparatus includes a container including the quantity of print material, a transfer mechanism associated with the container, and a sensor associated with the transfer mechanism. In some examples, the sensor is to communicate to the printing device information about the transfer of the quantity of print material through the dispenser mechanism.

Abstract: A dispensable substance container may include an elongate body encompassing a lumen, wherein the lumen is to contain the dispensable substance; a dispensable; substance dispensing nozzle attached to a first end on the elongate body; a sealing material within the lumen, wherein the sealing material is moveable, by a pushrod, within the lumen to push the dispensable substance out the dispensing tip; and a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body is to be severed along the structurally compromised portion by the pushrod.

Abstract: In an example, a container includes a housing with a memory resource embedded therein, an electrical contact coupled to an exterior of the container, and an electrical lead coupled to the memory resource and the electrical contact. In another example, a toner cartridge includes a controller embedded within a material of a housing and an electrical contact on an exterior surface of the housing and electrically coupled to the controller. In an example method of manufacturing a container, a memory resource is placed in a mold, material is injected into the mold such that the memory resource is embedded in the material, and the material is allowed to solidify.

Abstract: A device may include a dispensable substance container to hold a dispensable substance; a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle; and a frangible obstruction encompassing the dispensing nozzle and obstructing the opening of the dispensing nozzle wherein the frangible obstruction is to slide along the dispensing nozzle to uncover the opening when broken free from the dispensing nozzle by a wall of a receiving container during an engagement between the dispensable substance container and the receiving container.

Abstract: An example device capable of predicting print substance end-of-life (EOL) comprises a container to hold a print substance, the container comprising a refill port through which print substance is to be introduced into the container. The example device also comprises a processor to receive signals indicative of an amount of print substance introduced via the refill port. The processor is also to predict a print substance end-of-life (EOL) based on the amount of print substance introduced.

Abstract: A system for adding value to a host device via a mobile communication device is described. The system includes: a host device configured for providing additional value to be utilized, wherein the additional value includes at least one printing device function and is provided in response to receiving an authentication code; a central system configured for providing the authentication code for inputting into the host device to authorize the at least one printing device function to be utilized; and a mobile communication device configured for negotiating the additional value to be applied to the host device.
