Abstract
A printer driver comprising a separate page driver for analyzing print data and storing analysis data into a journal file, a journal file processor for retrieving the analysis data from the journal file, and a separate render driver for variably processing the print data depending on the type of stored analysis information, rendering the variably processed print data into picture elements having a reduced pixel depth, storing the picture elements into a band buffer, and providing the picture elements to a printer to produce high-quality printed images.
