Girlfriend's parents are talking about an issue with their printer in the next room. How long before I'm asked to fix it?

Yeah, another one of the legendary printer stories.

So yesterday my dad phones me up, and says: "Hi son so they changed our wifi and now the printer doesn't connect, how can I connect the printer to the wifi, and the computer to the printer?"

And then seemed confused when I told him I couldn't do it over the phone, that I usually have to fiddle with it physically. It baffles me that they think I'm some kind of all knowing wizard... And that I have memorized all the menus and setups required to do all this stuff...
