I'm deploying Windows 10 Kiosk Mode - Microsoft Edge with "As a public browser" manually by using Windows Settings (https://docs.microsoft.com/en-us/microsoft-edge/deploy/microsoft-edge-kiosk-mode-deploy
So that mean, Windows creates a normal local user is named "KioskUser0" by default and automatically login and start Microsoft Edge with defined websites.
It works fine with local printer (USB port) and problem happen with network printers. I don't know how to add network printer to this user (KioskUser0). I have been trying to Google without luck (these days).
