Method of printing with a personal computer and connected printer

摘要

A method of printing includes the steps of rendering continuous tone (“contone”) data to a pixel level and subsequently compressing the contone data in a personal computer. The bi-level data is rendered to a dot level and subsequently compressed in said personal computer. The method also includes the steps of transmitting the contone and bi-level data and decompressing the contone data and foreground bi-level data in parallel in a printer controller. The contone data is halftoned to bi-level color data. The foreground bi-level data is composited over the bi-level color data to create composited bi-level color image data. The steps of halftoning and compositing are performed in parallel. The method further includes the step of printing the composited bi-level color image data.
