Abstract
A method and system for simplifying required printer commands and facilitating print speed of both laser and inkjet printers is disclosed. When an operating system outputs a print page, a printer driving unit firstly estimates the time respectively consumed by applying the raster bitmap and high-level printer language approaches. Estimation of the printer driving unit is then routed into a print page processing unit for further processing. The print page is manipulated by using the raster bitmap approach in the print page processing unit when the time consumption of the print page estimated by using the raster bitmap approach is less than the other one. Otherwise, the print page is divided into a plurality of print bands for further processing. Complexity of the printer commands required for each print band is then estimated to judge whether the complexity is higher than a predetermined band threshold. All those print bands whose complexities are higher than the band threshold are processed to generate raster bitmap data firstly, and followed by encapsulating the data into printer commands before storing back to memory. All printer commands of the print bands are fetched from the m…
