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: 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: 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.
