Patent number: 11958306Abstract: In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.Type: GrantFiled: September 30, 2019Date of Patent: April 16, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Chen Zigdon, Mirit Shitrit, Liora Braun
