First step: Connect your printer to your WIFI

A receipt is printed with some information on it and a QR code
Scan the QR code with your phone and connect to the printer network
Once you click on it wait a bit and another receipt will be printed and scan the QR code or you can reach the page by typing the information you see directly in your browser here in the example “http://172.16.10.1”

How to reset your printer to connect your printer to another WIFI ?
On the back of your printer you have a small button that you can press with a pen
Press it and the button “ON” of the printer at the same time until a receipt is printed
It is done, your printer is reset !
Any insights if this method would work with other epson printers for printing labels?
**edit** If in doubt, factory reset and start again. Seemed to sort it.
Thanks for this - It doesn't work for me, either on my Linux (ubuntu 22.04) PoS boxes, or my Windows laptop. I've tried both Chrome & Firefox. I still get certificate errors.
The rouite to the printer:
Robustel R5020 Router > TP Link Switch > TP Link Archer AC Router (in access point mode) > TM-M30iii connected via wi-fi, on a static IP on my intranet.
My PoS boxes are running Ubuntu 22.04, on static internal IPs via the R5020, and all accessible on those IPs via SSH etc. They are on various subnets (in different rooms). The Printer web interface is accessible via it's fixed intranet IP from any subnet, but always shows up as having certificate errors
Do I need to run a DNS server for the intranet and use FQDNs rather than IPs, Is there any other troubleshooting/methodology I can go through?
