Abstract: The present disclosure describes fluid-wicking membranes, methods of making fluid-wicking membranes, and flow assay membranes. In one example, a fluid-wicking membrane can include a substrate and a porous coating layer over the substrate. The porous coating layer can include silica particles bound together by a polymeric binder. The silica particles can have an average particle size from greater than 1 pm to 50 pm. The porous coating layer can also include a surface-activating agent activating surfaces of the silica particles. The surface-activating agent can include aluminum chloride hydrate, a trivalent metal oxide, a tetravalent metal oxide, or a combination thereof.

Abstract: In an example implementation, an image transfer method includes inkjet printing a latex ink image onto a propylene-ethylene copolymer film extruded onto a single-layer image transfer sheet. The method includes putting the latex ink image and the single-layer image transfer sheet in contact with a substrate, and using heat and pressure to exclusively transfer the latex ink image onto the substrate, after which the single-layer transfer sheet is removed from the substrate.

Abstract: A media feed appliance can include a media pull guide to guide a print medium through a path while the print medium is manually pulled through the media feed appliance. The media feed appliance can also include a drive gear that is manually driven using frictional contact with the print medium while the print medium is pulled over a surface of the drive gear. The media feed appliance can also include a printer positioning port to position a manually actuatable printer to print on the print medium, wherein the drive gear of the media feed appliance is positioned to mechanically engage with a printer gear when the manually actuatable printer is docked at the port.

Abstract: There is provided a print apparatus and a media roll for the print apparatus, comprising a media identifier located on an end of a core section of the media roll. A type of media loaded into the print apparatus is determined by sensing the media identifier on the media roll using a non-contact sensor to scan the end of the core section.
