Raster image processing computer devices buffer pages of print-ready bitmaps waiting to be printed by a printing engine. A computer device monitors the printing speed of the printing engine and estimates the processing time for the raster image processing computer devices to produce the print-ready bitmaps, based on the complexity of the pages of the print job. The computer device compares the printing speed to the processing time to predict whether the number of pages of the print-ready bitmaps buffered by the raster image processing computer devices will increase or decrease. The computer device places one or more of the raster image processing computer devices in a reduced-power sleep mode when the number of pages of the print-ready bitmaps buffered is between a buffer minimum and a buffer maximum, and is predicted to not decrease.
