Abstract: A replaceable printing fluid supply carrier for a continuous ink supply system of a printer is described in some examples. The printing fluid supply carrier comprises a printing fluid container carrier and a cover part connected to the printing fluid container carrier. When the printing fluid supply carrier is installed to the printer with a supply door opening an opening to a printing fluid supply area the cover part covers the opening to the printing fluid supply area.

Abstract: Examples include printing devices configured for use with a plurality of replaceable supplies. A remaining amount of printing material may be monitored for each replaceable supply. A set of one or more replaceable supplies to be replaced may be determined based at least in part on the remaining amount of printing material for each replaceable supply and an amount of printing material corresponding to performing a service routine for supply replacement.

Abstract: In one example of the disclosure, environmental data indicative of an environmental factor measured at a printer is received via a network. The receipt of the environmental data is via an authorized non-anonymous data flow from the printer. Instructions for a service event to occur at the printer are determined based upon the environmental data. The service event instructions are sent, via the network, to the printer to cause the printer to perform the service event.

Abstract: A liquid permeable interconnect membrane for a liquid supply outlet, and a void between the interconnect membranes and an opposite void wall, the interconnect membrane being stiff enough to avoid unwanted pore deformation or contact with the opposite void wall.

Abstract: A fluid container ship cap seals a plurality of fluid interconnects of a fluid container during one or both of shipping and storage. The fluid container ship cap includes an elastomeric seal having a plurality of fluidic sealing members to seal a corresponding plurality of fluid interconnects. The fluid container ship cap further includes a rigid shell to rotate the fluid container ship cap about an axis of rotation at a fulcrum provided by a first fluidic sealing member of the plurality of fluidic sealing members. The elastomeric seal is affixed to the rigid shell.

Abstract: In one example, a fluid cartridge for an inkjet type liquid dispensing device includes a housing having a chamber therein for holding a liquid, a vent through which air may enter the chamber, and an outlet through which liquid may pass from the chamber out of the housing. A capillary material is disposed in the chamber between the vent and the outlet so that, when the capillary material is sufficiently depleted of liquid, the capillary material forms an airway from the vent to the outlet. The outlet configured to cause an abrupt break in a liquid connection in the outlet as air enters the outlet through the capillary material.

Abstract: An ink supply container includes a first portion and a second portion. The first portion is configured to hold a first volume of ink and is configured to be releasably connectable to a printhead. The second portion is configured to hold a second volume of ink and is in communication with the first portion. The second portion is configured to extend over a top of at least one other ink supply container upon releasable connection of the first portion of the container to a printhead assembly.

Abstract: A system for calculating a cost for printing is disclosed herein. A method for calculating the cost includes receiving a print job including print job characteristics and determining a printer classification for a printer. A controlled representative volume of ink to print the print job is determined, responsive to the print job characteristics and the printer classification. The controlled representative volume of ink is independent of a variation within the printer classification.

Abstract: In one embodiment, a cartridge includes: a housing having a chamber therein for holding a fluid; a vent at a first part of the chamber; a porous fluid holding material in the chamber; an outlet from the chamber; and a hole extending through the fluid holding material from the first part of the chamber to a second part of the chamber at a location away from the outlet such that the second part of the chamber is vented through the hole but the outlet is not vented through the hole.

Abstract: In one embodiment, a method for filling an ink pen having an ink holding chamber and an outlet from the chamber includes: covering the outlet with a first more dense ink holding material; adding ink to the first material; priming the pen; and adding a second less dense ink soaked ink holding material to the chamber.
