bump for help

@James547 good look, tp link tech guy told me to buy a WPA2 compatible printer and it will work fine. New printer bought and no further forward as it still won't connect. Very disappointed as tp link view is it is a printer issue and nothing to do with the Deco P9 🤷🏻‍♂️🤷🏻‍♂️

@James547 Hi. I had a similar problem with by system on a Halo s12 mesh (support query went to tp-link).  I got my wireless printer via the wireless mesh by enabling DMZ for the printer IP (192.168.1.113) within the mesh.  When adding the printer from my PC LAN i added it manual using TCP/IP using the mesh's IP (192.168192.168.0.139). It find the printer and printing works both from lan and wireless devices. 

Support was of no help - how did you go with your problem ?  Cheers. 

My config is below 

The setup is –

Hard wired LAN

Optus network Modem/router

IP 192.168.0.1 Gateway  with DHCP.

PC via LAN 192.168.0.81    

Halo s12

Lan connected to Optus modem/router

Wan

IP Address:192.168.0.139

Subnet Mask:255.255.255.0

Gateway:192.168.0.1

LAN  

192.168.1.1

With DHCP

Printer connected wireless to Halo s12 (192.168.1.113)  with DMZ enabled.

@NenadMelb I have a couple of questions for you. What do you refere to hard wired LAN?

the Optus modem/router is the one provided by your Internet Provider?

What is DMZ and where is it enabled?

I understand that the correct order is to first add the printer to the wireless network and then add it manually on your PC/MAC viaTCP/IP?

Thank you.

@James547 I have a similar problem with one difference - my printer is an old Samsung SCX-4729FD and has no wireless and so is connected to the Lan network and I can't print ffrom my wireless devices

@rfrimark 

I have Deco WiFi mesh, I also have Xerox printer with no wireless, it is connected to the LAN and I can print on it from any wired and wireless device in my household. If you can share description of your home network, I may be able to offer you a solution to your problem.

@Alexandre.  Thanks for the offered help.

I have 2 comps who have Lan connection to the router ( ISP provided).

Next to one of the comps the printer sits and is connected to a switch, which connects to the router.

The router has a connection to 1 comp, the switch, a socket that leads to the second connected port and the Cable provider's VOD connection.

The switch is connected to the main Deco and the printer.

I have a Deco on the ground level as well and on the first floor.

I hope these are the details you are asking for.

@James547 

Thx, I think I will try that.

But if I remember correctly, the Deco recommendation was to form a new network.

@rfrimark 

Both are valid recommendations. I prefer to start with simpler solutions. To "form a new network" and keep PCs connected by LAN you may need to do some rewiring in your house, perhaps buy a new networking switch, while Access Point mode is just configuration setting.
