Abstract:
A method for producing a predetermined sheet sequence of single sheets printed monochromatically and/or multi-colored in a printer or copier system, comprising the steps of:a) printing a first sequence of recording media at a first speed on one side or both sides monochromatically or in two colors in a monochromatic or highlight printer unit with a first paper transport channel that is individually driven and is fashioned as an independent structural unit;b) printing a second sequence of recording media on one side or both sides in full color in a color printer unit with a second paper transport channel that is individually drivable and fashioned as an independent structural unit, said second printing step being performed at a second, lower speed compared to the first speed;c) feeding at least one of the first and the second sequence of recording media to a paper path coupling module connected to said first and second paper transport channels; andd) producing the predetermined sheet sequence of the recording media from the first and the second sequence of recording media and the predetermined sheet sequence to at least one of a shared sheet collecting means and post-processing means in the predetermined sheet sequence; ande) separating incoming print data into monochromatic and color print job data with a synchronous control and communicating the respective print job data to the corresponding printer units.
