    Abstract: An example method of collecting liquid carrier from a vapour in a printing system includes: heating a vapour carrying a liquid carrier and passing the heated vapour carrying liquid carrier through a volume of liquid carrier. Liquid carrier carried in the heated vapour condenses into the volume of liquid carrier as it passes through the volume of liquid carrier.

    Abstract: In one example of the disclosure, a first transfer of ink is made from a photoconductor to a blanket in contact with the photoconductor. The blanket is to cycle along a path. The first transfer occurs at a first arc of the blanket path. A second transfer of the ink is made from the blanket to a media in contact with the blanket. The second transfer occurs at a second arc of the blanket path. A heat source located adjacent to a third arc of the blanket path is utilized to heat an external surface of the blanket. The heating is to occur following the second transfer of the ink.

    Abstract: In an example, an apparatus is described that includes a photosensitive imaging plate, an intermediate transfer member, and a heating unit. The photosensitive imaging plate attracts a layer of printing fluid. The intermediate transfer member contacts the photosensitive imaging plate and receives the layer of printing fluid from the photosensitive imaging plate. The heating unit includes an array of individually addressable heating elements and heats the intermediate transfer member in a manner that is spatially selective along two axes: a first axis in a direction of a width of the intermediate transfer member and a second axis in a direction of a rotation of the intermediate transfer member.

    Abstract: In one example, a system for transferring an ink image from a photoconductor to a print substrate includes a transfer member having a light absorbing exterior surface to receive a liquid LEP ink image from the photoconductor and to release a molten toner layer to a print substrate and a light source to expose a width of the surface carrying the liquid ink image to a light beam delivering enough power to transform the liquid ink image into a molten toner layer.

    Abstract: A method of operating an electrophotographic printer (100) to control the optical density of a printed image is described. The method comprises providing a printing substance on a transfer member (104); emitting a pulse of heat to heat the printing substance on the transfer member to increase flowability of the printing substance on the transfer member; and transferring, from the transfer member to a substrate (108), the printing substance heated by the pulse of heat so as to provide the printed image on the substrate.

    Abstract: In one example, a system for transferring an image from a photoconductor to a print substrate includes a transfer member having a removable blanket wrapped around a rotatable drum and a laser. The blanket has a light absorbing exterior surface to receive a liquid LEP ink image from the photoconductor and to release a layer of molten toner to a print substrate. As the drum rotates, the laser exposes a width of the exterior surface of the blanket carrying a liquid LEP ink image to a beam of coherent light that delivers enough power to transform the liquid LEP ink image into molten toner.
