Method and apparatus of operating a printer

摘要

An incremental printer comprising a plurality of printing elements grouped into redundant groups, each group being arranged to print substantially different portions of a given page of a printjob, the printer being adapted, when commencing a printjob, to control at least one redundant group of printing elements such that only a subset of the printing elements in that group are used to print, the printer being further arranged to subsequently increase the number of printing elements in that group which are used to print.
