Abstract
A duplex printing system and a printing method which enables printing of the second side of substrate in any desired order is provided. The printing system includes a printing unit, a reader and a processing unit. In the first pass, the printing unit receives a digital representation of a first image and at least one machine readable code and prints the first image and the machine readable code on a first side of a printing substrate. In the second pass, the reader identifies the printed machine readable code, preferably a bar-code, and provides it to the processing unit. The processing unit provides the digital representation of a second image associated with the machine readable code to the printing unit for printing a second image on a second side of the printing substrate, preferably, but not necessarily, in an orientation which is generally similar to the orientation of the printed first image and in registration therebetween.
