I am using Deco M5

I am also interested in this topic,
with the twist that my printer is connected to my main network(cable), and i would like to share it with my guests (guest wifi)

is this a possibility, so that i dont have to change the network preferences on my printer. (Canon I-Sensys MF633Cdw) every time a guest wants to print. ?

@Rooterguy

No,  the whole concept of the guest WiFi is to allow your guests access to the Internet, while locking them out of your personal network.  Either buy another cheap printer and connect it to the Guest WiFI (wow you would be the absolute best host!), or allow them into your personal LAN to print, there by opening all of your connected devices to what ever crapware is installed on your guest's device!

Other vendors (eg: google) offer you a way to share resources on your main network with guest network and vice versa.
