Printing processes are often triggered from production processes and converted into print jobs for printers via management systems (ERP, MES). With this type of process, it is not uncommon for synchronisation to be lost and the printer spoolers, which work asynchronously to production, can cause an offset between the printout and the actual goods produced. This problem can be solved with the Windows printer plug-in. Via interfaces such as REST, SQL, SOAP, SAP-RFC or similar, the OPC Router can obtain print data directly from the management systems, store it and then print it directly on request of the PLC synchronously with the produced product. Without spooler problems and absolutely validated by handshake between PLC and OPC Router.
