Patent number: 10377130Abstract: According to an example, in a method for mitigating damage to a plurality of drop generators in a printing system, data corresponding to an image to be printed on a media by the printing system may be accessed. In addition, the plurality of drop generators may be controlled to print the image on the media while mitigating damage to the plurality of drop generators and without shifting placement of the image on the media or shifting the plurality of drop generators in a direction perpendicular to a feed direction of the media.Type: GrantFiled: April 24, 2014Date of Patent: August 13, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Clayton L Holstun, Joshua A Mann, Lisa A Underwood

Patent number: 10160210Abstract: In an example, a non-transitory processor-readable medium stores code representing instructions that when executed by a processor cause a printing system to determine a text and line print mode or a graphics print mode to use for printing upcoming image content. The printing system selects a first nozzle column to print the image content when the text and line print mode is determined, and selects a second nozzle column to print the image content when the graphics print mode is determined.Type: GrantFiled: April 29, 2014Date of Patent: December 25, 2018Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Joshua A Mann, Clayton L Holstun, Lisa A Underwood
