Abstract: An example of a device (100) may include a valve body (108). The device (100) may include a printing substance transfer aperture (122) through the valve body (108). The device (100) may include a hood (138), fixed to the valve body (108), encompassing the printing substance transfer aperture (122) within a cavity between an external face (137) of the valve body (108) and the hood (138). The device (100) may include a printing substance dispensing nozzle (110) movable between a first position with an orifice (126) of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second position with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer aperture (122). The device (100) may include a dispensing-side gasket material (132) slide-able through the printing substance transfer aperture (122) when moving the printing substance dispensing nozzle (110) between the first position and the second position.

Abstract: In various examples, biased print gaskets can include a non-transitory machine-readable medium storing instructions executable by a processing resource to charge a material included in a gasket with a first bias voltage to repel print particles from a surface of the gasket, cease charging the material with the first bias voltage and charge the material with a second bias to attract print particles to a surface of the gasket.

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 dispensable substance container may include a printing substance dispensing nozzle comprising a first material. The dispensable substance container an elongate body, comprising a wall, comprising a second material encompassing a cavity to contain a dispensable substance, and an attachment portion to attach the elongate body to the printing substance dispensing nozzle; and a structurally compromised portion of the elongate body extending along a length of the elongate body, wherein the elongate body and the attachment portion are to be severed along the structurally compromised portion by a pushrod moveable through the cavity to expel the dispensable substance out the dispensing nozzle.
