Hi,

If you are unable to connect to the Brother printer when the PC is connected via Ethernet cable, then this probably means the Ethernet cable is connected to a different network than the printer.

Can you explain a bit more detailled who is connected to the Deco network and how the Powerline adapters are connected?

As for you question about being connected via cable and Wi-Fi simultanously. What does actually happen when both are connected? Is the printer not accessible when the cable is also plugged into the PC?

I only have one network at home, a combination of mesh via Deco setup and powerline adapters. The wired connection is from the main Deco M4 (modem > Deco > PA8010P) which then I connect the satellite Deco throughout the house with (PA8010P > Deco).

The printer does not have a LAN port so it's either wifi or USB cable. The PC is connected with ethernet on this same network but right now if I want to print I need to connect to wifi and unplug the ethernet cable because, AFAIK, the wifi won't work if I have a live wired network. So, back to my question, is there any way both wifi and wired connection can work simultaneously so I don't need to plug and unplug my PC to print?

If the Ethernet cable and the Wi-Fi connect you to the same network, then you cannot have both connected at the same time, as this creates a network loop. (this is a general issue in networking, not just TP-Link hardware)

But if the Ethernet cable connects you to the same network as the Wi-Fi connection, then the printer should be accessible via the PC's Ethernet connection as well (even when the printer is connected via Wi-Fi), unless some restrictions have been set up. (like, printer connected to "Guest" network or device isolation is enabled, but I am not sure about the features available on the Deco M4)

Yes, you can have both the Ethernet connection and Wi-Fi connection active simultaneously on your PC. This allows you to print over Wi-Fi to your Brother printer while still utilizing the faster Ethernet connection for internet access. No need to constantly plug/unplug the cable.

  @RobertSterrett how do I do this? Because I have tried but it won't print. So initially while connected to Wifi I plugged in the LAN cable (by way of powerline) to the PC and the wifi icon changed to wired connection. Are there additional setting I have to apply?

I suggest we should first ascertain whether you are connecting to one and the same local area network two times or whether you are connecting to two separate local area networks. (when Ethernet and Wi-Fi are both connected)

I think the best way would be if you connect both Ethernet and Wi-Fi at the same time, then go to the "Network and Sharing Center" of Windows (link is within the Control Panel) and get us all the IPv4 addresses of the local network for each connection. Below are some screenshots to illustrate how to get there and what we need to see and what information you can black out.
