Patent number: 9539829Abstract: According to an example, printing on a media web may include outputting a first instruction to print a first frame on the media web. A first encoder count of an encoder may be determined between a first alignment mark and an end of frame for the first frame. Additionally, a second encoder count of the encoder may be determined between the first alignment mark for the first frame and a second alignment mark for a second frame. A difference value may then be calculated between the first encoder count and the second encoder count. Based on the difference value, a scaling factor of the encoder may be determined. Accordingly, another instruction may be output to print another frame on the media web based on the scaling factor.Type: GrantFiled: October 31, 2013Date of Patent: January 10, 2017Assignee: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: Bruce A. Stephens, David C. Collins
