Disclosed is a method that allows complex data streams to be printed in a smaller number of continuous horizontal sweeps rather than a greater number of short sweeps. Serial line printers processing complex host data streams that perform such functions as justified text, multiple font changes on a line, or APA and text on the same line, often perform these at a much lower throughput than the standard texts used to measure throughput for marketing claims. This has led in the past to negative customer impressions and unusable systems for certain applications. The method described allows complex data streams to be processed prior to printing in a manner that allows most complex lines to be processed before the previous line is completed.
