Abstract
This invention provides a scheduling scheme that uses an estimated rasterization execution time (RET) to improve the productivity of printers, particularly color printers. Because print jobs have different levels of complexities, a longer RET may be require for some jobs than for others. For example, a print job which includes color graphics, color print, different font changes or a variety of style formats such as, italic, bold and other styles, will have a longer RET than a simple black and white print job. If a print job is pre-scanned to estimate the RET before the print job arrives at the printer, it is possible to schedule those print jobs with a shorter RET ahead of those print jobs with a longer RET, thus improving productivity of the printer.
