Why my PS driver generates color drawings but grayscale images?
When the driver generates PostScript stream for monochrome printer it often converts color images to grayscale for better transmission time, faster rendering, and lower resource usage. Conversion of vector objects to grayscale doesn’t save mush space or time. So the driver leaves it to the PostScript interpreter. This problem often happens when the job is printed to Generic PostScript printer driver. Generic driver is not the best one. It is limited to the common subset of PostScript language available on most printers. It is monochome, has small choice of media, fonts, no special features.The PostScript file from Generic driver will print on wide wariety of printers but many features will be missing. Although it appears like every printer uses a special driver it is the same driver configured for different printers. The driver takes configuration parameters from PPD file. When possible the native PPD file should be used. The Acrobat Distillir PPD is a good choice to generate a color P
