I mean that the extracted cert that's going around is from the client (Bambu Connect) side. Everything it would get used for is a function of the client and how it talks /to/ the printer.
Even if it is used to sign some communications, it doesn't matter if it's expired or not on the server side (the printer side), unless the server chooses not to accept it. And then updating it would be a matter of updating Connect; the client.
There's no reason -- other than hyperbole -- to infer that a certificate which expires on the client side will cause the printer to stop doing anything.
For a web-y example, think of how a website which needs a client cert for auth -- like lots of gov't stuff -- would handle a client cert expiring. It'd either accept it anyway, or reject it. But it wouldn't mean the website breaks. And thus claims of that client certificate's expiration being a killswitch for printers is simply wrong.
