Swathing parallel pipeline architecture

摘要

Disclosed is a method of processing a print job, the print job being received in a page description language format. The method identifies a number of print heads on a printer targeted for printing said print job. The method processes the print job in the page description language format to produce a plurality of intermediate jobs, in which a number of the intermediate jobs is determined by the number of print heads. The intermediate jobs have an intermediate format between the page description language format and a rasterized image format. The method renders each of a plurality of intermediate jobs to a rasterized image in a renderer associated with each of the print heads independently of one another and external input.

1. A method of rendering a print job using a plurality of print heads, said method comprising:
inputting the print job in a page description language format to render multiple pages in a row on a web; processing the print job to produce a plurality of intermediate jobs in an intermediate graphical format based on the plurality of print heads across the web, the intermediate jobs having the intermediate graphical format between the page description language format and a rasterized image format; and rendering, independently of one another, each of the plurality of intermediate jobs to a rasterized image in a renderer associated with each of the print heads to be printed by a corresponding one of the print heads.
