I need suggestions on how to print from a 1769-L32E PLC to an Ethernet-connected Zebra Printer. Any insights, examples, or code snippets you can provide would be highly valued. Share your setup tips to help me streamline this process effectively. Thank you!
Many individuals may not be acquainted with this particular printer. Could you provide a link to the manual? Additionally, I'm curious if it supports Ethernet CIP. Thanks, Stu.
Looking for a reliable desktop printer under $500? The Zebra G-Series GK420T is a great option that we have found to be dependable. While we are open to other printer options, this model has served us well in the past. Check out the detailed specs and manuals for the Zebra G-Series GK420T on their official website.
Wondering if this information is useful? Here is an example of how to send commands using VB/C# TCP/IP. In this code snippet, we are setting the IP address to "10.3.14.42" and the port to 9100. The ZPL command included in the code is: "^XA^FO50,50^A0N50,50^FDHello, World!^FS^XZ". This code snippet demonstrates how to send commands via TCP/IP using VB/C#.
Zebra printer interfacing is a common topic that often arises, yet it seems we lack samples in our archives. Zebra printers utilize their own protocol, whether through serial or TCP/IP. Unlike Modbus or CIP, they do not follow an industrial application protocol. The 1769-L30ER model can send generic string data over Ethernet using the Socket Object, whereas the 1769-L32E would require a converter or interface. A good starting point would be to test the Zebra printer's response to bytes sent over TCP/IP using a terminal program like RealTerm, before moving on to messaging with the Socket Object in the 1769-L30ER model.
For now, let's switch back to RS-232 communication at a baud rate of 9600, no parity, 1 stop bit. We have successfully utilized these types of printers with Micrologix and CompactLogix systems for many years. The printer is equipped with Ethernet connectivity for PC-based applications with a required driver installation. Additionally, it features an old-fashioned D-Sub 9 RS-232 port for direct connection. If you're looking for a cost-effective solution, utilize a port on your CompactLogix and utilize ASCII string output to communicate with the printer. Alternatively, if Ethernet is a must, consider implementing an RTA ASCII Gateway to convert Ethernet data from the CompactLogix into ASCII for the printer. The PLC programming strings typically include commands such as "^XA" to start a label, "~SD20" to adjust print darkness, "^FO110,50" to set the field origin, "^ADN" to select font type, "^FDYour Text Here" for field data, and "^XZ" to end the label. Zebra provides comprehensive resources on ZPL and EPL ASCII commands for creating labels with barcodes and text. Though it may be a slow start, once you successfully print your first label, the following projects will progress smoothly.
One method I've found to be effective when dealing with similar scenarios is to establish communication between your PLC and printer via the MSG instruction. You should set your 1769-L32E PLC as a client, and the Zebra printer as a server. You then need to format your message in ZPL (Zebra Programming Language) because that’s what the printer understands. About ZPL, you may need to manually enter it into a string in your PLC program, or as an easier approach you could probably keep it in a text file on your computer and read it in as needed. I used this method when I had to print labels from my PLC application and it streamlined the process significantly. Make sure to keep a good hold on the commands as ZPL is rather finicky. Good luck!
To print from a 1769-L32E PLC to an Ethernet-connected Zebra printer, you'll want to use Ethernet messaging (MSG) instructions. Start by ensuring your printer is configured with a static IP address on the same network as your PLC. In your PLC program, use the MSG instruction to send formatted print commands to the printer's IP address, typically using a command like the ZPL (Zebra Programming Language). You can also make use of the print buffer to prepare your data before sending it. Don’t forget to check the printer's manual for any specific communication settings! It might also help to set up a simple test to verify connection and data transmission before deploying it in a production environment. Good luck!
You might want to consider using the Ethernet/IP protocol since your 1769-L32E PLC supports it; many Zebra printers can handle this over their print server interface. Look into the ability to send commands via TCP/IP sockets—this can help you format the print jobs correctly. I recommend using a basic instruction set in your PLC program to open a socket connection to the printer’s IP address and then send your label data as raw text commands. Also, make sure to test with the Zebra Setup Utility to ensure your printer is correctly configured for network printing. If you need more specific code examples, I can share some snippets that I've used successfully in similar setups!
To print from a 1769-L32E PLC to an Ethernet-connected Zebra printer, you'll want to leverage the Ethernet capabilities of the PLC, using a communication protocol like TCP/IP. First, make sure your printer is properly configured and connected to the network. You can use Rockwell's Ethernet/IP library to format your print commands, then send the data using the `Send` instruction. Depending on your Zebra printer’s model, you might need to use ZPL (Zebra Programming Language) to format your print jobs. One example could be constructing a string for ZPL and sending it as a byte array. Also, check your printer's IP address and ensure any necessary firewall settings are adjusted. Good luck, and feel free to ask if you hit any snags!
