Special requirements apply to printing systems that are integrated in a labeling system. Here the printers must be easy to change and made for 3-shift continuous operation. An interface to connect to control systems via signal exchange to start printing and return error messages is an important requirement for using these printing systems
In order to ensure easy replacement, uniform dimensions for installing the print module have been independently adopted by manufacturers. The interfaces for connection to the PLC of the system differ from manufacturer, but generally the basic functions are always supported
