Combining smart printing technology and the TW PLC Printer software, RACO’s Smart Printing Solution is a sophisticated product labeling system that is designed to eliminate mislabeling of parts and containers. This is accomplished by allowing you to print directly from a Programmable Logic Controller (PLC) to the label printer without the need to maintain a PC in the middle of the chain.

Instead of relying on pre-printing of shipping labels, the PLC will direct your smart printer to produce up to 255 different predetermined labels for parts or containers. In short, the PLC always knows which part is being made and sends the corresponding signals to your printer, effectively automating and error-proofing your label printing process.

A Smart Printing solution from RACO eliminates mislabeling caused by human error on even the most commonly mislabeled parts, including left-hand/right-hand, multi-colored, similar, and sequenced parts. Additionally, serialized part label data is stored in a database, which provides an audit trail and streamlines recalls and warranty claims. Because the printers receive their data from the PLC and do not require their own programming, they are effectively interchangeable, allowing you to avoid excessive downtime or reprogramming if a printer requires maintenance.


Using TW PLC software, RACO’s Smart Printing solution allows you to exchange data between PC databases and the printer through either wired Ethernet or wireless connectivity. Variable data such as shift codes and employee IDs can be managed through a portable terminal, which can be supplemented with optional real-time date and time stamping for enhanced traceability. The system can also be combined with a label applicator accessory for automated part and container labeling.
