Abstract

In a printing system or method, two printing units apply printing ink onto a recording material, each printing unit having multiple apparatuses with a respective microprocessor controller. The microprocessor controllers are connected with one another via a respective data bus segment and each data bus segment has multiple data lines. The two data bus segments of the two printing units are connected with a bus switch. The bus switch has a data switch to connect a respective one of the lines of the one data bus segment with the corresponding line of the other data bus segment, a respective terminating resistor being provided for each data bus segment. The terminating resistors are connected with a respective terminating switch coupled with the data switches such that either all terminating switches are open and all data switches are closed, or all terminating switches are closed and all data switches are open.
