Abstract: A print head module for delivering ink to a print head comprising a module venting system comprising a one-time vent built into the interior of the print head module in which, when an amount of ink comes in contact with the one-time vent, air is prevented from passing through the one-time vent. A system for delivering ink to a print head comprising a print head, a external reservoir of ink, and a print head module comprising a one-time vent built into the interior of the print head module and fluidly coupling the print head to the external reservoir of ink, in which, when an amount of ink comes in contact with the one-time vent within the print head module, air is prevented from passing through the one-time vent.

Abstract: An inkjet printing system, fluid ejection system and method thereof are disclosed. The fluid ejection system includes a fluid ejection device and a determination module to determine a supply condition based on the count value output by the converter module. The fluid ejection device includes a fluid supply chamber to store fluid, an ejection chamber including a nozzle and a corresponding ejection member to selectively eject the fluid through the nozzle, a pressure sensor unit having a sensor plate to output a voltage value corresponding to a cross-sectional area of an amount of fluid in the ejection chamber. The fluid ejection system also includes a converter module to output a count value corresponding to the voltage value output by the pressure sensor unit.

Abstract: In one example of the disclosure, subscription data is received from a computer via a web application. The subscription data is indicative of a subscription for a printer that is, or is to be, connected to a supply of marking agent. The subscription authorizes the printer to consume a subscription amount of marking agent. A browser plug-in is sent to the computer, via the web application, to enable the computer to discover the printer via a wireless connection. Identification data obtained via the browser plug-in is received from the computer printer. The identification data is utilized to establish an operative connection with the printer. A credit is sent to the printer, via the operative connection, to authorize consumption of at least a portion of the subscription amount from the supply.

Abstract: A recording medium and a method for making the recording medium are disclosed. The recording medium includes a core substrate. The core substrate includes a base having two opposed surfaces. The base includes from about 40% to about 70% organic material and from about 30% to about 60% inorganic material. The core substrate also includes a mineral coating layer disposed on one or both of the two opposed surfaces of the base. The mineral coating layer has a water-soluble or water-dispersible binder and mineral materials. An adhesion layer is disposed on the mineral coating layer. A surface treatment layer is disposed on the adhesion layer, and the surface treatment layer includes organic fibrous material.

Abstract: An image forming apparatus includes a substrate receiving member, a fluid applicator unit, and an air recirculator assembly. The substrate receiving member may selectively receive a substrate. The fluid applicator unit may selectively eject a first set of drops to the substrate received by the substrate receiving member in a print mode and a second set of drops in a maintenance mode. The air recirculater assembly may direct air to form an air barrier across the print zone to redirect at least one of aerosol and particulates from crossing through the air barrier and onto the substrate, to filter the at least one of the aerosol and particulates to form filtered air, and to form the air barrier with the filtered air.

Abstract: The present disclosure provides non-Newtonian inkjet inks and related methods. In one example, a non-Newtonian inkjet ink can comprise a gelator in an amount ranging from 0.1% to 10% by weight based on the total weight of the non-Newtonian inkjet ink; a salt in an amount of 0.05% to 20% by weight based on the total weight of the non-Newtonian inkjet ink; a sugar alcohol in an amount of 1% to 25% by weight based on the total weight of the non-Newtonian inkjet ink; and an organic solvent. The gelator and the salt can form a structured network, where the inkjet ink has a first dynamic viscosity ranging from 25 cps to 10,000 cps at a first state and a second dynamic viscosity ranging from 1 cps to 50 cps at a second state.
