Use Wi-Fi printers when Ethernet cabling is not possible. Wi-Fi can work well, but the printer must stay on a strong, stable network. Use Wi-Fi for:
  1. Locations where Ethernet cables cannot be run.
  2. Temporary stations.
  3. Low-movement printers with strong signal.
Avoid Wi-Fi for printers that are far from the router, behind thick walls, or critical during peak service if Ethernet is available.

​
Supported Starter Models

Wi-Fi setup is supported for these starter printer families when the model supports Wi-Fi network printing and ESC/POS or raw TCP printing:

​
Network Requirements

  1. The printer must be connected to the same Wi-Fi network as the POS device.
  2. The Wi-Fi signal must be strong where the printer is placed.
  3. The printer must have a reachable IP address.
  4. The printer port must be known. Many receipt printers use 9100.
  5. The Wi-Fi name and password should not change without updating the printer.
  6. The printer IP should be reserved on the router when possible.

​
Plato Setup

In Plato, create a printer and set Connection Config to Network. Enter the printer IP address and port, then connect the printer to the POS device from Connected Devices. For the full flow, see Configure And Connect A Printer.

Quick Wi-Fi Checks

If the printer does not print:
  1. Confirm the printer is still connected to Wi-Fi.
  2. Confirm the POS device is on the same Wi-Fi network.
  3. Move the printer closer to the router if printing works sometimes and fails sometimes.
  4. Restart the printer after Wi-Fi or router changes.
  5. Confirm the IP address in Plato matches the printer self-test page.
