Where is the WPS Pin? On a Dell E525W

Where is the WPS Pin? On a Dell E525W

I’m trying to open the Dell Document Hub .

In the Hub it says “No printer Installed { I have the printer working and printing

Connected via USB

Just want to get the Hub working

I get the message = “unable to use the Dell Document Hub .”

“for windows 10 Add a printer under Devices ”

1^st I see the Dell E525W under Printer & Scanners and see that the is a App available for this device

So I click on that next I click on manage it opens

2^nd I click on “Open printer app“ That takes me back to “unable to use the Dell Document Hub .”

3^rd I try to add a printer under Add Printer and Scanner

It finds the Dell E525W-2242D6

I the get the popup asking to enter the WPS Pin for you printer .

I tried to put the WPS Pin from my Comcast router into the space , but I get “That Did Not Work”

FYI =Comcast router Security: WPA2PSK-AES

Where is the WPS Pin? On a Dell E525W

Thank You
