Print Media Bottom Portion Printing

US Patent:
8641160, Feb 4, 2014
Filed:
Oct 28, 2011
Appl. No.:
13/284410
Inventors:
Erick Blane Kinas - Camas WA, US
Alvin Marion Post - Vancouver WA, US
Assignee:
Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
B41J 29/38, B41J 2/04, B41J 2/01
US Classification:
347 14, 347 54, 347102
Abstract:
A method of printing includes ejecting ink drops onto a bottom portion of a print media from ink orifices of a first portion of a printhead; after ejecting ink drops from the first portion of the printhead, advancing the print media; and after advancing the print media, ejecting ink drops onto the bottom portion of the print media from ink orifices of a second portion of the printhead. The second portion of the printhead is smaller than the first portion of the printhead and excludes ink orifices toward an end of the printhead opposite a direction of the advancing of the print media.
