  • Patent number: 6069704
    Abstract: A method of scheduling a sequence of pages to be printed with a printer and a printer/photocopier incorporating this method are disclosed. The printer has a printing station and a duplex loop for returning duplex sheets, of which a first page has been printed on one side, to the printing station for printing the second page on the second side, the duplex loop accommodating a predetermined number N of sheets at a time, such that skips in the stream of pages are filled with first pages of duplex sheets or with simplex sheets, without changing the desired order in which the sheets are completed. When a new print command for printing a new job occurs, the pages of the new job are appended to the remainder of the previously scheduled sequence that has not yet been printed, with re-scheduling of the thus assembled sequence.
