Abstract
A simplified process for duplex printing on a simplex-only printing system in which plural page document duplex electronic print jobs generated with a duplex printing control signal are sent to be printed. If such duplex print jobs are sent to a duplex printer then they are printed normally without user interactive intervention. However, when such duplex print jobs are sent to a simplex printing system which does not have automatic duplex printing capability, then, the simplex printing system detects the duplex printing control and temporarily electronically stores the duplex print job until a duplex document printing command signal is entered, whereupon, the duplex print job is automatically split up into two different split simplex electronic print jobs, of alternate first and second side pages, and only the first side pages are initially printed and outputted, and then the simplex printing system automatically pauses to wait for these copy sheets printed on only their first sides to be reloaded into the copy sheets input of the simplex printing system, and for a second sides print command, whereupon the other, second, sides, are automatically printed on the copy sheets to produce a complete collated plural page duplex printed print job. The simplex printing system can automatically determine whether the first sides to be printed are printed with the odd pages or the even pages. The duplex document printing command signal is preferably entered into the interactive user interface of the simplex printing system by a user then present.
