I've a working BE25 setup with wired backhaul. Majority of the Wifi devices can connect with a stable link but I've an EPSON L3151 printer which is just unable to connect.
Sometimes it appears on the DHCP list but the connection just breaks up.
Here is the log from deco side (XX-XX-XX-XX-XX-XX MAC address is the printer):

I've tried many things without any success:
* Connect to IOT network with 2.Ghz only
* Beamforming off
* WPA/WPA2 only
Please help me because this makes the whole new net setup useless.
I see there might be a new firmware update for your deco
I would go into your deco app and see if you can download and install that version 1st.
If the new version isn't there or doesn't fix the issue let us know
You asked for this. 
It is possible your printer is unable to handle WiFi mesh, because it only expects single WiFi router in the house broadcasting SSID. That would explain why printer works with TP-Link Archer AX53 but not with TP-Link Deco mesh.
This is how I would suggest to test this theory:
1. Enable IoT network with its default settings. I know, you tried that already but please stay with me as it is only the first step;
2. Delete all Satellite Deco from Deco app. In Deco app, you should only see Main Deco after that. Power off all Satellite Deco.
3. Connect printer to IoT network, also move printer close to Main Deco to make sure WiFi signal is not too weak. This is just for testing, after it you can move printer back.
In that configuration- does printer app connect to printer and is printer connection to WiFi stable? If Yes and Yes, it is printer, sorry. I can provide workaround for you, but this is printer issue.
If with just Main Deco you can't make that work, undo all changes I asked you to do and wait for feedback from TP-Link Engineers.
