Alternative Setup: mC-Print3 SteadyLAN

If you experience issues with your Wifi signal, and you are currently using a McPrint3 setup, you can provide an internet connection to your tablet plugged into the printer with a USB-Lightning (Apple devices) or USB-C (Android and Windows devices) cable.

Note: You should only connect an Ethernet cable if using SteadyLAN. SteadyLAN should only be used if your Wi-Fi signal is inconsistent or poor. If you have a good Wi-Fi signal, use the recommended set-up. When not using SteadyLAN, the printer should not have the Ethernet cable plugged in.

Limitations: The SteadyLAN function wired LAN connection via USB-A (2.4A) provides stable communication, however the communication speed is approximately 1 Mbps and may be slower than the wireless LAN.

Connect an Ethernet cable

1. Connect an Ethernet cable to the LAN port on the printer.
2. Connect the other end of the Ethernet cable to an available port on the TrendNet network switch included with your Greenbits hardware kit, or connect directly to your router.

Using the integrated scale and printer at the same time

When using the printer at the same time as the integrated scale while using SteadyLAN setup, ensure that:

• The mC-Print3 is connected to the network via ethernet cable.
• The integrated scale is connected to your network via ethernet cable.
• And validate that the iPad and the integrated scale are on the same network.
