Cannot print to wireless printer when Privacy is connected

[marmackco]

If I want to print something from my android cell phone or tablet  to my Canon wireless printer I have to turn Privacy off. Other wise I get a message that the printer is unavailable even tho' it is shown in the list of available printers. This is not a deal breaker, just a pain in the nether regions. BTW I have tried several printer apps (Mopria, Canon and the Samsung service) and they all do the same.

I have a Moto 7 cell running Android 10 and a Galaxy Tab with Android 12

That could be because when you use a VPN your Exit Node is somewhere on the Internet and the device redirects all communication to the Internet (WAN) while the Cannon WiFi address is on the Intranet (LAN).  Once you use a VPN the POV is on the outside looking in instead of the inside looking out.
