A method of processing data in a printing system comprising a first plurality of printing devices and a second plurality of print-related devices, wherein data is transmitted over a common print line bus is provided. The printing devices and print-related devices are connected to the common print line bus by means of associated print line bus adapters to constitute a printshop environment. The method comprises identifying plural devices from the first plurality of printing devices and the second plurality of print-related devices required for performing a requested print processing, said identified devices constituting a print line segment of the first and second plurality of devices; assigning a segment identifier to the identified devices constituting said print line segment; and configuring the print line bus adapters of those devices that have been assigned said segment identifier in that each device of said segmented devices is able to filter out data that is destined to said respective device from the common print line bus.
